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.

Give up the inlining expansion for strcmp/strncmp/memcmp on a target where the type of the call has same or narrower presicion than unsigned char. Change char to unsigned char for strcmp/strncmp when expand them to a sequence of byte comparisons. Due to C standard section 7.24.4: The sign of a nonzero value returned by the comparison functions memcmp, strcmp, and strncmp is determined by the sign of the difference between the values of the first pair of characters (both interpreted as unsigned char) that differ in the objects being compared. bootstraped and tested on both X86 and Aarch64. no regression.

3nd Patch for PR78009
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78809 Inline strcmp with small constant strings The design doc for PR78809 is at: https://www.mail-archive.com/gcc@gcc.gnu.org/msg83822.html this patch is for the third part of change of PR78809. C. for strcmp (s1, s2), strncmp (s1, s2, n), and memcmp (s1, s2, n) if the result is NOT used to do simple equality test against zero, one of "s1" or "s2" is a small constant string, n is a constant, and the Min value of the length of the constant string and "n" is smaller than a predefined threshold T, inline the call by a byte-to-byte comparision sequence to avoid calling overhead. adding test case strcmpopt_5.c into gcc.dg for part C of PR78809. adding test case strcmpopt_6.c into gcc.dg to test the following case: When the specified length exceeds one of the arguments of the call to memcmp, the call to memcmp should NOT be inlined.

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 |

Replace FMA_EXPR with one internal fn per optab
There are four optabs for various forms of fused multiply-add: fma, fms, fnma and fnms. Of these, only fma had a direct gimple representation. For the other three we relied on special pattern- matching during expand, although tree-ssa-math-opts.c did have some code to try to second-guess what expand would do. This patch removes the old FMA_EXPR representation of fma and introduces four new internal functions, one for each optab. IFN_FMA is tied to BUILT_IN_FMA* while the other three are independent directly-mapped internal functions. It's then possible to do the pattern-matching in match.pd and tree-ssa-math-opts.c (via folding) can select the exact FMA-based operation. The BRIG & HSA parts are a best guess, but seem relatively simple. 2018-05-18 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * doc/sourcebuild.texi (scalar_all_fma): Document. * tree.def (FMA_EXPR): Delete. * internal-fn.def (FMA, FMS, FNMA, FNMS): New internal functions. * internal-fn.c (ternary_direct): New macro.

Add ability to remap file names in __FILE__, etc (PR other/70268)
This commit adds the -fmacro-prefix-map option that allows remapping of file
names in __FILE__, __BASE_FILE__, and __builtin_FILE(), similar to how
-fdebug-prefix-map allows to do the same for debug information.
Additionally, it adds -ffile-prefix-map which can be used to specify both
mappings with a single option (and, should we need to add more -f*-prefix-map
options in the future, those as well).

poly_int: REG_ARGS_SIZE
This patch adds new utility functions for manipulating REG_ARGS_SIZE notes and allows the notes to carry polynomial as well as constant sizes. The code was inconsistent about whether INT_MIN or HOST_WIDE_INT_MIN should be used to represent an unknown size.

Convert STARTING_FRAME_OFFSET to a hook
I took the documentation of the FRAME_GROWS_DOWNWARD behaviour from the version that was in most header files, since the one in the manual seemed less clear. The patch deliberately keeps FIRST_PARM_OFFSET(FNDECL) in microblaze_starting_frame_offset; this seems to be a port-local convention and takes advantage of the fact that FIRST_PARM_OFFSET doesn't read FNDECL. 2017-10-23 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (starting_frame_offset): New hook. * doc/tm.texi (STARTING_FRAME_OFFSET): Remove in favor of...

Turn CONSTANT_ALIGNMENT into a hook
The definition:
#define CONSTANT_ALIGNMENT(EXP, ALIGN) \
(TREE_CODE (EXP) == STRING_CST \
&& (ALIGN) < BITS_PER_WORD ? BITS_PER_WORD : (ALIGN))
was very common, so the patch adds a canned definition for that,
called constant_alignment_word_strings. Some ports had a variation
that used a port-local FASTEST_ALIGNMENT instead of BITS_PER_WORD;
the patch uses constant_alignment_word_strings if FASTEST_ALIGNMENT
was always BITS_PER_WORD and a port-local hook function otherwise.

Make more use of int_mode_for_size
This patch converts more places that could use int_mode_for_size instead
of mode_for_size. This is in preparation for an upcoming patch that
makes mode_for_size itself return an opt_mode.
require () seems like the right choice in expand_builtin_powi
because we have got past the point of backing out. We go on to do:
op1 = expand_expr (arg1, NULL_RTX, mode2, EXPAND_NORMAL);
if (GET_MODE (op1) != mode2)
op1 = convert_to_mode (mode2, op1, 0);
which would be invalid for (and have failed for) BLKmode.
In get_builtin_sync_mode and expand_ifn_atomic_compare_exchange,
the possible bitsizes are {8, 16, 32, 64, 128}, all of which give
target-independent integer modes (up to TImode). The comment above
the call in get_builtin_sync_mode makes clear that an integer mode
must be found.
We can use require () in expand_builtin_atomic_clear and
expand_builtin_atomic_test_and_set because there's always an integer
mode for the boolean type. The same goes for the POINTER_SIZE request
in layout_type. Similarly we can use require () in combine_instructions
and gen_lowpart_common because there's always an integer mode for
HOST_BITS_PER_WIDE_INT (DImode when BITS_PER_UNIT == 8), and
HOST_BITS_PER_DOUBLE_INT (TImode).
The calls in aarch64_function_value, arm_function_value,
aapcs_allocate_return_reg and mips_function_value_1 are handling
cases in which a big-endian target passes or returns values at
the most significant end of a register. In each case the ABI
constrains the size to a small amount and does not handle
non-power-of-2 sizes wider than a word.
The calls in c6x_expand_movmem, i386.c:emit_memset,
lm32_block_move_inline, microblaze_block_move_straight and
mips_block_move_straight are dealing with expansions of
block memory operations using register-wise operations,
and those registers must have non-BLK mode.
The reason for using require () in ix86_expand_sse_cmp,
mips_expand_ins_as_unaligned_store, spu.c:adjust_operand and
spu_emit_branch_and_set is that we go on to emit non-call
instructions that use registers of that mode, which wouldn't
be valid for BLKmode.

PR82045: Avoid passing machine modes through "..."
PR82045 is about a bootstrap failure on sparc-sun-solaris2.11. The problem was that we were passing the new machine_mode wrapper classes through "..." to emit_library_call(_value), which then read them back as ints instead. The simplest fix seemed to be replace "..." with an array of rtx_mode_ts, then provide wrappers for the common cases. This bulks out rtl.h a bit, but it does make things a bit more typesafe. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR bootstrap/82045 * rtl.h (emit_library_call_value_1): Declare.

[9/77] Add SCALAR_FLOAT_TYPE_MODE
This patch adds a macro that extracts the TYPE_MODE and forcibly converts it to a scalar_float_mode. The forcible conversion includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P. This becomes important as more static type checking is added by later patches. It has the additional benefit of bypassing the VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition in TYPE_MODE; in release builds the new macro is a simple field access. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree.h (SCALAR_FLOAT_TYPE_MODE): New macro. * builtins.c (expand_builtin_signbit): Use it instead of TYPE_MODE. * fold-const.c (fold_convert_const_real_from_fixed): Likewise.

[4/77] Add FOR_EACH iterators for modes
The new iterators are:
- FOR_EACH_MODE_IN_CLASS: iterate over all the modes in a mode class.
- FOR_EACH_MODE_FROM: iterate over all the modes in a class,
starting at a given mode.
- FOR_EACH_WIDER_MODE: iterate over all the modes in a class,
starting at the next widest mode after a given mode.
- FOR_EACH_2XWIDER_MODE: same, but considering only modes that
are two times wider than the previous mode.
- FOR_EACH_MODE_UNTIL: iterate over all the modes in a class until
a given mode is reached.
- FOR_EACH_MODE: iterate over all the modes in a class between
two given modes, inclusive of the first but not the second.
These help with the stronger type checking added by later patches,
since every new mode will be in the same class as the previous one.

Fix expand_builtin_atomic_fetch_op for pre-op (PR80902)
__atomic_add_fetch adds a value to some memory, and returns the result. If there is no direct support for this, expand_builtin_atomic_fetch_op is asked to implement this as __atomic_fetch_add (which returns the original value of the mem), followed by the addition. Now, the __atomic_add_fetch could have been a tail call, but we shouldn't perform the __atomic_fetch_add as a tail call: following code would not be executed, and in fact thrown away because there is a barrier after tail calls. This fixes it. PR middle-end/80902 * builtins.c (expand_builtin_atomic_fetch_op): If emitting code after a call, force the call to not be a tail call. From-SVN: r249603 |

Support __builtin_isinf_sign for new floating-point types (PR middle-end/77269).
The __builtin_isinf_sign folding uses a type-specific signbit built-in function, meaning it only works for the types float, double and long double, not for types such as _FloatN, _FloatNx, __float128. Since the signbit built-in function is now type-generic, that can be used unconditionally, much as the code uses the type-generic isinf built-in function unconditionally, and this patch makes it do so, thereby enabling __builtin_isinf_sign (which glibc uses to expand the isinf macro since that macro in glibc traditionally provided the stronger guarantees about the return value given by __builtin_isinf_sign) to work for all floating-point types. The test gcc.dg/torture/builtin-isinf_sign-1.c needs updating because it tests that comparisons of calls to __builtin_isinf_sign to conditional expressions involving __builtin_isinf and __builtin_signbit* get optimized away, and with a change of what particular built-in function for signbit is used, GCC doesn't notice the expressions with type-generic and non-type-generic built-in functions are equivalent at -O0 or -O1 (it does optimize away the original test at -O2). Bootstrapped with no regressions on x86_64-pc-linux-gnu.

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.

PR 68432: Add a target hook to control size/speed optab choices
The problem in the PR is that some i386 optabs FAIL when optimising for size rather than speed. The gimple level generally needs access to this information before calling the generator, so this patch adds a new hook to say whether an optab should be used when optimising for size or speed. It also has a "both" option for cases where we want code that is optimised for both size and speed. I've passed the optab to the target hook because I think in most cases that's more useful than the instruction code. We could pass both if there's a use for it though. At the moment the match-and-simplify code doesn't have direct access to the target block, so for now I've used "both" there.

Extend tree-call-cdce to calls whose result is used
For -fmath-errno, builtins.c currently expands calls to sqrt to:
y = sqrt_optab (x);
if (y != y)
[ sqrt (x); or errno = EDOM; ]
The drawbacks of this are:
- the call to sqrt is protected by the result of the optab rather
than the input. It would be better to check __builtin_isless (x, 0),
like tree-call-cdce.c does.
- the branch isn't exposed at the gimple level and so gets little
high-level optimisation.
- we do this for log too, but for log a zero input produces
-inf rather than a NaN, and sets errno to ERANGE rather than EDOM.
This patch moves the code to tree-call-cdce.c instead, with the optab
operation being represented as an internal function. This means that
we can use the existing argument-based range checks rather than the
result-based checks and that we get more gimple optimisation of
the branch.
Previously the pass was only enabled by default at -O2 or above,
but the old builtins.c code was enabled at -O. The patch therefore
enables the pass at -O as well.
The previous patch to cfgexpand.c handled cases where functions
don't (or are assumed not to) set errno, so this patch makes
the builtins.c code dead.
Tested on x86_64-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabi
and visium-elf (for the EDOM stuff).

Add internal math functions
This patch adds internal functions for simple FLT_FN built-in functions, in cases where an associated optab already exists. Unlike some of the built-in functions, these internal functions never set errno. LDEXP is an odd-one out in that its second operand is an integer. All the others operate on uniform types. The patch also adds a function to query the internal function associated with a built-in function (if any), and another to test whether a given gcall could be replaced by a call to an internal function on the current target (as long as the caller deals with errno appropriately).

Move #undef DEF_BUILTIN* to builtins.def
I was confused at first why tree-core.h was undefining DEF_BUILTIN_CHKP before defining it, then undefining it again after including builtins.def. This is because builtins.def provides a default definition of DEF_BUILTIN_CHKP, but leaves it up to the caller to undefine it where necessary. Similarly to the previous internal-fn.def patch, it seems more obvious for builtins.def to #undef things unconditionally. One argument might have been that keeping preprocessor stuff out of the .def files makes it easier for non-cpp parsers. In practice though we already have #ifs and multiline #defines, so single-line #undefs should be easy in comparison. Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ada/ * gcc-interface/utils.c: Don't undef DEF_BUILTIN. gcc/c-family/ * c-common.c: Don't undef DEF_BUILTIN. gcc/jit/ * jit-builtins.c: Don't undef DEF_BUILTIN. gcc/lto/ * lto-lang.c: Don't undef DEF_BUILTIN. gcc/ * builtins.def: #undef DEF_BUILTIN and DEF_BUILTIN_CHKP * builtins.c, genmatch.c, tree-core.h: Don't undef them here.

Move const char * -> int/fp folds to fold-const-call.c
This patch moves folds that deal with constant string arguments and
return a constant integer or floating-point value. For example, it
handles strcmp ("foo", "bar") but not strstr ("foobar", "bar"),
which wouldn't currently be accepted by the gimple folders.
The builtins.c folding for strlen (via c_strlen) is a bit more general
than what the fold-const-call.c code does (and more general than we need
for the gimple folders). I've therefore left it as-is, even though it
partially duplicates the new code.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

Move c_getstr to fold-const.c
Upcoming patches to fold-const-call.c want to use c_getstr, which is currently defined in builtins.c. The function doesn't really do anything related to built-ins, and I'd rather not make fold-const-call.c depend on builtins.c and builtins.c depend on fold-const-call.c, so this patch moves the function to fold-const.c instead.

Move constant folds for maths functions to new file
The new routines operate on the built-in enum rather than on tree decls. The idea is to extend this to handle internal functions too, with a combined enum for both. The patch also moves fold_fma too, with the same prototype. The long-term plan is to replace FMA_EXPR with an internal function, for consistency with the way that things like SQRT will be handled.

Allow real_format to be passed to more real.h functions
Most real.h routines used machine modes to specify the format of an operation and converted that to a float_format * internally. Some also had alternative versions that accepted a float_format *. In an upcoming patch it seemed more convenient for the callers I was adding to use float_format directly, since the callers need to examine the format themselves for other reasons. This patch therefore replaces the machine_mode arguments with a new class that allows both machine modes and float_format pointers to be used. Tested on x86_64-linux-gnu, arm-linux-gnueabi and aarch64-linux-gnu. gcc/ * real.h (format_helper): New.

Rename logb and significand folds
fold_builtin_logb and fold_builtin_significand now only handle constant arguments, so this patch renames them to fold_const..., to match fold_const_builtin_pow. The idea is to differentiate constant-only folds so that they can be moved to a const_binop-like function in future. The functions also had some unnecessary calls to STRIP_NOPS, which I think are left over from code that has already moved to match.pd. Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ * builtins.c (fold_builtin_logb): Rename to... (fold_const_builtin_logb): ...this and remove STRIP_NOPS call. (fold_builtin_significand): Rename to... (fold_const_builtin_significand): ...this and remove STRIP_NOPS call. (fold_builtin_1): Update accordingly. From-SVN: r229433 |

Remove constant handling from fold_builtin_{,f}abs
fold_builtin_fabs and fold_builtin_abs had code to handle constant arguments, but this simply duplicated what the following fold_build1_loc would do for ABS_EXPR. Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ * builtins.c (fold_builtin_fabs): Remove constant handling. (fold_builtin_abs): Likewise. From-SVN: r229427 |
