libsanitizer: mid-end: Introduce stack variable handling for HWASAN
Handling stack variables has three features.
1) Ensure HWASAN required alignment for stack variables
When tagging shadow memory, we need to ensure that each tag granule is
only used by one variable at a time.
This is done by ensuring that each tagged variable is aligned to the tag
granule representation size and also ensure that the end of each
object is aligned to ensure the start of any other data stored on the
stack is in a different granule.
This patch ensures the above by forcing the stack pointer to be aligned
before and after allocating any stack objects. Since we are forcing
alignment we also use `align_local_variable` to ensure this new alignment
is advertised properly through SET_DECL_ALIGN.
2) Put tags into each stack variable pointer
Make sure that every pointer to a stack variable includes a tag of some
sort on it.
The way tagging works is:
1) For every new stack frame, a random tag is generated.
2) A base register is formed from the stack pointer value and this
random tag.
3) References to stack variables are now formed with RTL describing an
offset from this base in both tag and value.
The random tag generation is handled by a backend hook. This hook
decides whether to introduce a random tag or use the stack background
based on the parameter hwasan-random-frame-tag. Using the stack
background is necessary for testing and bootstrap. It is necessary
during bootstrap to avoid breaking the `configure` test program for
determining stack direction.
Using the stack background means that every stack frame has the initial
tag of zero and variables are tagged with incrementing tags from 1,
which also makes debugging a bit easier.
Backend hooks define the size of a tag, the layout of the HWASAN shadow
memory, and handle emitting the code that inserts and extracts tags from a
pointer.
3) For each stack variable, tag and untag the shadow stack on function
prologue and epilogue.
On entry to each function we tag the relevant shadow stack region for
each stack variable. This stack region is tagged to match the tag added to
each pointer to that variable.
This is the first patch where we use the HWASAN shadow space, so we need
to add in the libhwasan initialisation code that creates this shadow
memory region into the binary we produce. This instrumentation is done
in `compile_file`.
When exiting a function we need to ensure the shadow stack for this
function has no remaining tags. Without clearing the shadow stack area
for this stack frame, later function calls could get false positives
when those later function calls check untagged areas (such as parameters
passed on the stack) against a shadow stack area with left-over tag.
Hence we ensure that the entire stack frame is cleared on function exit.

c++: Add __builtin_clear_padding builtin - C++20 P0528R3 compiler side [PR88101]
The following patch implements __builtin_clear_padding builtin that clears the padding bits in object representation (but preserves value representation). Inside of unions it clears only those padding bits that are padding for all the union members (so that it never alters value representation). It handles trailing padding, padding in the middle of structs including bitfields (PDP11 unhandled, I've never figured out how those bitfields work), VLAs (doesn't handle variable length structures, but I think almost nobody uses them and it isn't worth the extra complexity). For VLAs and sufficiently large arrays it uses runtime clearing loop instead of emitting straight-line code (unless arrays are inside of a union). The way I think this can be used for atomics is e.g. if the structures are power of two sized and small enough that we use the hw atomics for say compare_exchange __builtin_clear_padding could be called first on the address of expected and desired arguments (for desired only if we want to ensure that most of the time the atomic memory will have padding bits cleared), then perform the weak cmpxchg and if that fails, we got the value from the atomic memory; we can call __builtin_clear_padding on a copy of that and then compare it with expected, and if it is the same with the padding bits masked off, we can use the original with whatever random padding bits in it as the new expected for next cmpxchg. __builtin_clear_padding itself is not atomic and therefore it shouldn't be called on the atomic memory itself, but compare_exchange*'s expected argument is a reference and normally the implementation may store there the current value from memory, so padding bits can be cleared in that, and desired is passed by value rather than reference, so clearing is fine too. When using libatomic, we can use it either that way, or add new libatomic APIs that accept another argument, pointer to the padding bit bitmask, and construct that in the template as alignas (_T) unsigned char _mask[sizeof (_T)]; std::memset (_mask, ~0, sizeof (_mask)); __builtin_clear_padding ((_T *) _mask); which will have bits cleared for padding bits and set for bits taking part in the value representation. Then libatomic could internally instead of using memcmp compare for (i = 0; i < N; i++) if ((val1[i] & mask[i]) != (val2[i] & mask[i])) 2020-11-20 Jakub Jelinek <jakub@redhat.com> PR libstdc++/88101 gcc/ * builtins.def (BUILT_IN_CLEAR_PADDING): New built-in function. * gimplify.c (gimplify_call_expr): Rewrite single argument BUILT_IN_CLEAR_PADDING into two-argument variant. * gimple-fold.c (clear_padding_unit, clear_padding_buf_size): New const variables.

builtins: Add DFP signaling NaN built-in functions
Add built-in functions __builtin_nansd32, __builtin_nansd64 and __builtin_nansd128 to return signaling NaNs of decimal floating-point types, analogous to the functions already present for binary floating-point types. This patch, independent of <https://gcc.gnu.org/pipermail/gcc-patches/2020-October/557136.html> (pending review), is in preparation for adding the <float.h> macros for such signaling NaNs that are in C2x, analogous to the macros for other types that are in that patch. Bootstrapped with no regressions for x86_64-pc-linux-gnu. Also ran the new tests for powerpc64le-linux-gnu to confirm they do work in the case (hardware DFP) where floating-point exceptions are supported for DFP. gcc/ 2020-11-06 Joseph Myers <joseph@codesourcery.com> * builtins.def (BUILT_IN_NANSD32, BUILT_IN_NANSD64) (BUILT_IN_NANSD128): New built-in functions. * fold-const-call.c (fold_const_call): Handle the new built-in functions. * doc/extend.texi (__builtin_nansd32, __builtin_nansd64) (__builtin_nansd128): Document. * doc/sourcebuild.texi (Effective-Target Keywords): Document fenv_exceptions_dfp. gcc/testsuite/ 2020-11-06 Joseph Myers <joseph@codesourcery.com> * lib/target-supports.exp (check_effective_target_fenv_exceptions_dfp): New. * gcc.dg/dfp/builtin-snan-1.c, gcc.dg/dfp/builtin-snan-2.c: New tests. |

[nvptx] Add type arg to TARGET_LIBC_HAS_FUNCTION
GCC has a target hook TARGET_LIBC_HAS_FUNCTION, which tells the compiler
which functions it can expect to be present in libc.
The default target hook does not include the sincos functions.
The nvptx port of newlib does include sincos and sincosf, but not sincosl.
The target hook TARGET_LIBC_HAS_FUNCTION does not distinguish between sincos,
sincosf and sincosl, so if we enable it for the sincos functions, then for
test.c:
...
long double x, a, b;
int main (void) {
x = 0.5;
a = sinl (x);
b = cosl (x);
printf ("a: %f\n", (double)a);
printf ("b: %f\n", (double)b);
return 0;
}
...
we introduce a regression:
...
$ gcc test.c -lm -O2
unresolved symbol sincosl
collect2: error: ld returned 1 exit status
...
Add a type argument to target hook TARGET_LIBC_HAS_FUNCTION_TYPE, and use it
in nvptx_libc_has_function_type to enable sincos and sincosf, but not sincosl.
Build and reg-tested on x86_64-linux.

Removal of HSA offloading from gcc and libgomp
This patch removes the generation of HSAIL from the compiler, the HSA
offloading plugin from libgomp and the associated testsuite tests and
infrastructure bits from the respective testsuites.
Apart from removal of the obvious files, I removed bits that I found
by searching for HSA related terms and by re-tracing my steps and
looking at the patches that introduced HSA in the first place. I did
not remove everything these patches brought in, for example:
- the mechanism to pass offload-target specific info from the application to
the offloading plugin - but the same mechanism is also used to
communicate number of teams and the thread limit to all offload targets.
- run_func hook in gomp_device_descr stays too, although now it is
not used. If some future offload target would like the ability to
refuse to offload some functions, it can use it. It is easy to
remove as a follow-up if it is considered clutter, though.
- configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH
and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too.
- Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant
from gomp-constants.h) appears in the source of the amdgcn libgomp
plugin, although I tend to think that code path is not ever used
and this patch certainly removes it from the compiler.
Nevertheless, it seems it has potential value beyond HSAIL and so
I've kept it, it can of course always be easily removed in the
future of GCN folk abandon it too.
- I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA
need to stay indefinitely too just so that no future offload
target picks that number.
- I have kept dg-require-effective-target
offload_device_nonshared_as requirement of thests which have it.
It is quite probable I missed some small HSA artifacts but those
should be easy to remove later as we find them.

Add support for __builtin_bswap128
This patch introduces a new builtin named __builtin_bswap128 on targets where TImode is supported, i.e. 64-bit targets only in practice. The implementation simply reuses the existing double word path in optab, so no routine is added to libgcc (which means that you get two calls to _bswapdi2 in the worst case). gcc/ChangeLog: * builtin-types.def (BT_UINT128): New primitive type.

[C++ coroutines] Initial implementation.
This is the squashed version of the first 6 patches that were split to
facilitate review.
The changes to libiberty (7th patch) to support demangling the co_await
operator stand alone and are applied separately.
The patch series is an initial implementation of a coroutine feature,
expected to be standardised in C++20.
Standardisation status (and potential impact on this implementation)
--------------------------------------------------------------------
The facility was accepted into the working draft for C++20 by WG21 in
February 2019. During following WG21 meetings, design and national body
comments have been reviewed, with no significant change resulting.
The current GCC implementation is against n4835 [1].
At this stage, the remaining potential for change comes from:
* Areas of national body comments that were not resolved in the version we
have worked to:
(a) handling of the situation where aligned allocation is available.
(b) handling of the situation where a user wants coroutines, but does not
want exceptions (e.g. a GPU).
* Agreed changes that have not yet been worded in a draft standard that we
have worked to.
It is not expected that the resolution to these can produce any major
change at this phase of the standardisation process. Such changes should be
limited to the coroutine-specific code.
ABI
---
The various compiler developers 'vendors' have discussed a minimal ABI to
allow one implementation to call coroutines compiled by another.
This amounts to:
1. The layout of a public portion of the coroutine frame.
Coroutines need to preserve state across suspension points, the storage for
this is called a "coroutine frame".
The ABI mandates that pointers into the coroutine frame point to an area
begining with two function pointers (to the resume and destroy functions
described below); these are immediately followed by the "promise object"
described in the standard.
This is sufficient that the builtins can take a coroutine frame pointer and
determine the address of the promise (or call the resume/destroy functions).
2. A number of compiler builtins that the standard library might use.
These are implemented by this patch series.
3. This introduces a new operator 'co_await' the mangling for which is also
agreed between vendors (and has an issue filed for that against the upstream
c++abi). Demangling for this is added to libiberty in a separate patch.
The ABI has currently no target-specific content (a given psABI might elect
to mandate alignment, but the common ABI does not do this).
Standard Library impact
-----------------------
The current implementations require addition of only a single header to
the standard library (no change to the runtime). This header is part of
the patch.
GCC Implementation outline
--------------------------
The standard's design for coroutines does not decorate the definition of
a coroutine in any way, so that a function is only known to be a coroutine
when one of the keywords (co_await, co_yield, co_return) is encountered.
This means that we cannot special-case such functions from the outset, but
must process them differently when they are finalised - which we do from
"finish_function ()".
At a high level, this design of coroutine produces four pieces from the
original user's function:
1. A coroutine state frame (taking the logical place of the activation
record for a regular function). One item stored in that state is the
index of the current suspend point.
2. A "ramp" function
This is what the user calls to construct the coroutine frame and start
the coroutine execution. This will return some object representing the
coroutine's eventual return value (or means to continue it when it it
suspended).
3. A "resume" function.
This is what gets called when a the coroutine is resumed when suspended.
4. A "destroy" function.
This is what gets called when the coroutine state should be destroyed
and its memory released.
The standard's coroutines involve cooperation of the user's authored function
with a provided "promise" class, which includes mandatory methods for
handling the state transitions and providing output values. Most realistic
coroutines will also have one or more 'awaiter' classes that implement the
user's actions for each suspend point. As we parse (or during template
expansion) the types of the promise and awaiter classes become known, and can
then be verified against the signatures expected by the standard.
Once the function is parsed (and templates expanded) we are able to make the
transformation into the four pieces noted above.
The implementation here takes the approach of a series of AST transforms.
The state machine suspend points are encoded in three internal functions
(one of which represents an exit from scope without cleanups). These three
IFNs are lowered early in the middle end, such that the majority of GCC's
optimisers can be run on the resulting output.
As a design choice, we have carried out the outlining of the user's function
in the front end, and taken advantage of the existing middle end's abilities
to inline and DCE where that is profitable.
Since the state machine is actually common to both resumer and destroyer
functions, we make only a single function "actor" that contains both the
resume and destroy paths. The destroy function is represented by a small
stub that sets a value to signal the use of the destroy path and calls the
actor. The idea is that optimisation of the state machine need only be done
once - and then the resume and destroy paths can be identified allowing the
middle end's inline and DCE machinery to optimise as profitable as noted
above.
The middle end components for this implementation are:
A pass that:
1. Lowers the coroutine builtins that allow the standard library header to
interact with the coroutine frame (these fairly simple logical or
numerical substitution of values, given a coroutine frame pointer).
2. Lowers the IFN that represents the exit from state without cleanup.
Essentially, this becomes a gimple goto.
3. Sets the final size of the coroutine frame at this stage.
A second pass (that requires the revised CFG that results from the lowering
of the scope exit IFNs in the first).
1. Lower the IFNs that represent the state machine paths for the resume and
destroy cases.
Patches squashed into this commit:
[C++ coroutines 1] Common code and base definitions.
This part of the patch series provides the gating flag, the keywords,
cpp defines etc.
[C++ coroutines 2] Define builtins and internal functions.
This part of the patch series provides the builtin functions
used by the standard library code and the internal functions
used to implement lowering of the coroutine state machine.
[C++ coroutines 3] Front end parsing and transforms.
There are two parts to this.
1. Parsing, template instantiation and diagnostics for the standard-
mandated class entries.
The user authors a function that becomes a coroutine (lazily) by
making use of any of the co_await, co_yield or co_return keywords.
Unlike a regular function, where the activation record is placed on the
stack, and is destroyed on function exit, a coroutine has some state that
persists between calls - the 'coroutine frame' (thus analogous to a stack
frame).
We transform the user's function into three pieces:
1. A so-called ramp function, that establishes the coroutine frame and
begins execution of the coroutine.
2. An actor function that contains the state machine corresponding to the
user's suspend/resume structure.
3. A stub function that calls the actor function in 'destroy' mode.
The actor function is executed:
* from "resume point 0" by the ramp.
* from resume point N ( > 0 ) for handle.resume() calls.
* from the destroy stub for destroy point N for handle.destroy() calls.
The C++ coroutine design described in the standard makes use of some helper
methods that are authored in a so-called "promise" class provided by the
user.
At parse time (or post substitution) the type of the coroutine promise
will be determined. At that point, we can look up the required promise
class methods and issue diagnostics if they are missing or incorrect. To
avoid repeating these actions at code-gen time, we make use of temporary
'proxy' variables for the coroutine handle and the promise - which will
eventually be instantiated in the coroutine frame.
Each of the keywords will expand to a code sequence (although co_yield is
just syntactic sugar for a co_await).
We defer the analysis and transformatin until template expansion is
complete so that we have complete types at that time.
2. AST analysis and transformation which performs the code-gen for the
outlined state machine.
The entry point here is morph_fn_to_coro () which is called from
finish_function () when we have completed any template expansion.
This is preceded by helper functions that implement the phases below.
The process proceeds in four phases.
A Initial framing.
The user's function body is wrapped in the initial and final suspend
points and we begin building the coroutine frame.
We build empty decls for the actor and destroyer functions at this
time too.
When exceptions are enabled, the user's function body will also be
wrapped in a try-catch block with the catch invoking the promise
class 'unhandled_exception' method.
B Analysis.
The user's function body is analysed to determine the suspend points,
if any, and to capture local variables that might persist across such
suspensions. In most cases, it is not necessary to capture compiler
temporaries, since the tree-lowering nests the suspensions correctly.
However, in the case of a captured reference, there is a lifetime
extension to the end of the full expression - which can mean across a
suspend point in which case it must be promoted to a frame variable.
At the conclusion of analysis, we have a conservative frame layout and
maps of the local variables to their frame entry points.
C Build the ramp function.
Carry out the allocation for the coroutine frame (NOTE; the actual size
computation is deferred until late in the middle end to allow for future
optimisations that will be allowed to elide unused frame entries).
We build the return object.
D Build and expand the actor and destroyer function bodies.
The destroyer is a trivial shim that sets a bit to indicate that the
destroy dispatcher should be used and then calls into the actor.
The actor function is the implementation of the user's state machine.
The current suspend point is noted in an index.
Each suspend point is encoded as a pair of internal functions, one in
the relevant dispatcher, and one representing the suspend point.
During this process, the user's local variables and the proxies for the
self-handle and the promise class instanceare re-written to their
coroutine frame equivalents.
The complete bodies for the ramp, actor and destroy function are passed
back to finish_function for folding and gimplification.
[C++ coroutines 4] Middle end expanders and transforms.
The first part of this is a pass that provides:
* expansion of the library support builtins, these are simple boolean
or numerical substitutions.
* The functionality of implementing an exit from scope without cleanup
is performed here by lowering an IFN to a gimple goto.
This pass has to run for non-coroutine functions, since functions calling
the builtins are not necessarily coroutines (i.e. they are implementing the
library interfaces which may be called from anywhere).
The second part is the expansion of the coroutine IFNs that describe the
state machine connections to the dispatchers. This only has to be run
for functions that are coroutine components. The work done by this pass
is:
In the front end we construct a single actor function that contains
the coroutine state machine.
The actor function has three entry conditions:
1. from the ramp, resume point 0 - to initial-suspend.
2. when resume () is executed (resume point N).
3. from the destroy () shim when that is executed.
The actor function begins with two dispatchers; one for resume and
one for destroy (where the initial entry from the ramp is a special-
case of resume point 0).
Each suspend point and each dispatch entry is marked with an IFN such
that we can connect the relevant dispatchers to their target labels.
So, if we have:
CO_YIELD (NUM, FINAL, RES_LAB, DEST_LAB, FRAME_PTR)
This is await point NUM, and is the final await if FINAL is non-zero.
The resume point is RES_LAB, and the destroy point is DEST_LAB.
We expect to find a CO_ACTOR (NUM) in the resume dispatcher and a
CO_ACTOR (NUM+1) in the destroy dispatcher.
Initially, the intent of keeping the resume and destroy paths together
is that the conditionals controlling them are identical, and thus there
would be duplication of any optimisation of those paths if the split
were earlier.
Subsequent inlining of the actor (and DCE) is then able to extract the
resume and destroy paths as separate functions if that is found
profitable by the optimisers.
Once we have remade the connections to their correct postions, we elide
the labels that the front end inserted.
[C++ coroutines 5] Standard library header.
This provides the interfaces mandated by the standard and implements
the interaction with the coroutine frame by means of inline use of
builtins expanded at compile-time. There should be a 1:1 correspondence
with the standard sections which are cross-referenced.
There is no runtime content.
At this stage, we have the content in an inline namespace "__n4835" for
the CD we worked to.
[C++ coroutines 6] Testsuite.
There are two categories of test:
1. Checks for correctly formed source code and the error reporting.
2. Checks for transformation and code-gen.
The second set are run as 'torture' tests for the standard options
set, including LTO. These are also intentionally run with no options
provided (from the coroutines.exp script).

Mark C2x built-in functions as such.
Various built-in functions that GCC has as extensions are now standard functions in C2x. This patch adds DEF_C2X_BUILTIN and uses it to mark them as such. Some of the so-marked functions were previously DEF_EXT_LIB_BUILTIN, while some DFP ones were DEF_GCC_BUILTIN (i.e. __builtin_* only); both sets become DEF_C2X_BUILTIN. This in turn requires flag_isoc2x to be defined in various front ends using builtins.def. As the semantics of the built-in functions should already be tested, the tests added only verify that they are declared in C2x mode but not in C11 mode. The test of DFP built-in functions being declared for C2x goes in gcc.dg/dfp/, as while such built-in functions currently don't depend on whether DFP is supported, that looks like a bug to me (see bug 91985), so it seems best for the tests not to depend on exactly how that bug might be fixed. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * builtins.def (DEF_C2X_BUILTIN): New macro. (exp10, exp10f, exp10l, fabsd32, fabsd64, fabsd128, nand32) (nand64, nand128, roundeven, roundevenf, roundevenl, strdup) (strndup): Use DEF_C2X_BUILTIN. * coretypes.h (enum function_class): Add function_c2x_misc. gcc/ada: * gcc-interface/utils.c (flag_isoc2x): New variable. gcc/brig: * brig-lang.c (flag_isoc2x): New variable. gcc/lto: * lto-lang.c (flag_isoc2x): New variable. gcc/testsuite: * gcc.dg/c11-builtins-1.c, gcc.dg/c2x-builtins-1.c, gcc.dg/dfp/c2x-builtins-dfp-1.c: New tests.

Add __builtin_speculation_safe_value
This patch defines a new intrinsic function __builtin_speculation_safe_value. A generic default implementation is defined which will attempt to use the backend pattern "speculation_safe_barrier". If this pattern is not defined, or if it is not available, then the compiler will emit a warning, but compilation will continue. Note that the test spec-barrier-1.c will currently fail on all targets. This is deliberate, the failure will go away when appropriate action is taken for each target backend. gcc: * builtin-types.def (BT_FN_PTR_PTR_VAR): New function type.

2nd Patch for PR78009
Patch for PR83026 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78809 Inline strcmp with small constant strings https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83026 missing strlen optimization for strcmp of unequal strings The design doc for PR78809 is at: https://www.mail-archive.com/gcc@gcc.gnu.org/msg83822.html this patch is for the second part of change of PR78809 and PR83026: B. for strncmp (s1, s2, n) (!)= 0 or strcmp (s1, s2) (!)= 0 B.1. (PR83026) When the lengths of both arguments are constant and it's a strcmp: * if the lengths are NOT equal, we can safely fold the call to a non-zero value. * otherwise, do nothing now. B.2. (PR78809) When the length of one argument is constant, try to replace the call with a __builtin_str(n)cmp_eq call where possible, i.e: strncmp (s, STR, C) (!)= 0 in which, s is a pointer to a string, STR is a string with constant length, C is a constant. if (C <= strlen(STR) && sizeof_array(s) > C) { replace this call with __builtin_strncmp_eq (s, STR, C) (!)= 0 } if (C > strlen(STR) { it can be safely treated as a call to strcmp (s, STR) (!)= 0 can handled by the following strcmp. } strcmp (s, STR) (!)= 0 in which, s is a pointer to a string, STR is a string with constant length. if (sizeof_array(s) > strlen(STR)) { replace this call with __builtin_strcmp_eq (s, STR, strlen(STR)+1) (!)= 0 } later when expanding the new __builtin_str(n)cmp_eq calls, first expand them as __builtin_memcmp_eq, if the expansion does not succeed, change them back to call to __builtin_str(n)cmp. adding test case strcmpopt_2.c and strcmpopt_4.c into gcc.dg for part B of PR78809 adding test case strcmpopt_3.c into gcc.dg for PR83026 From-SVN: r261039 |

Add minimal _FloatN, _FloatNx built-in functions.
This patch adds a minimal set of built-in functions for the new _FloatN and _FloatNx types. The functions added are __builtin_fabs*, __builtin_copysign*, __builtin_huge_val*, __builtin_inf*, __builtin_nan* and __builtin_nans* (where * = fN or fNx). That is, 42 new entries are added to the enum of built-in functions and the associated array of decls, where not all of them are actually supported on any one target. These functions are believed to be sufficient for libgcc (complex multiplication and division use __builtin_huge_val*, __builtin_copysign* and __builtin_fabs*) and for glibc (which also depends on complex multiplication from libgcc, as well as using such functions itself). The basic target-independent support for folding / expanding calls to these built-in functions is wired up, so those for constants can be used in static initializers, and the fabs and copysign built-ins can always be expanded to bit-manipulation inline (for any format setting signbit_ro and signbit_rw, which covers all formats supported for _FloatN and _FloatNx), although insn patterns for fabs (abs<mode>2) and copysign (copysign<mode>3) will be used when available and may result in more optimal code. The complex multiplication and division functions in libgcc rely on predefined macros (defined with -fbuilding-libgcc) to say what the built-in function suffixes to use with a particular mode are. This patch updates that code accordingly, where previously it involved a hack supposing that machine-specific suffixes for constants were also suffixes for built-in functions. As with the main _FloatN / _FloatNx patch, this patch does not update code dealing only with optimizations that currently has cases only covering float, double and long double, though some such cases are straightforward and may be covered in a followup patch. The functions are defined with DEF_GCC_BUILTIN, so calls to the TS 18661-3 functions such as fabsf128 and copysignf128, without the __builtin_, will not be optimized. As noted in the original _FloatN / _FloatNx patch submission, in principle the bulk of the libm functions that have built-in versions should have those versions extended to cover the new types, but that would require more consideration of the effects of increasing the size of the enum and initializing many more functions at startup. I don't know whether target-specific built-in functions can readily be made into aliases for target-independent functions, but if they can, it would make sense to do so for the x86, ia64 and rs6000 *q functions corresponding to these, so that they can benefit from the architecture-independent folding logic and from any optimizations enabled for these functions in future, and so that less target-specific code is needed to support them.
