fron function value type to function type.
From-SVN: r5084
(init_decl_processing): When making SIZETYPE, start with name in
SIZE_TYPE. If -traditional, use a signed version of that type, if it
is unsigned.
From-SVN: r4752
(shadow_tag_warned): Let warned have three values, so that a mere
warning doesn't prevent a pedwarn. Don't skip the error call at the
end on accounted of warned.
From-SVN: r4203
(current_function_prototype_file,
current_function_prototype_line): New variables.
(start_function): Set them.
(store_parm_decls): Use them for error and warning messages.
From-SVN: r3782
(store_parm_decls,combine_parm_decls): Call layout_decl
for a parm declared float when it is changed to double under a
traditional compilation.
From-SVN: r3652
(grokdeclarator): Make `long long' work even with
-pedantic, despite the warning.
(declare_parm_level): Unconditionally store 1.
(pushdecl): Criterion for no warning is, next level up
is a parm level.
From-SVN: r3555
* c-decl.c (c_decode_option): Set WARN_UNINITIALIZED to 2 with
-Wall, being careful to preserve it if it's already set.
* cp-decl2.c (lang_decode_option): Likewise.
* toplev.c (main): Warn about using -Wuninitialized without -O.
From-SVN: r3250
not unsigned_char_..., as index type for ..._array_type_node.
(pushdecl): Avoid multiple extern decl mismatch warnings
when previous decl is built-in.
From-SVN: r3167
with previous prototype declaration.
(init_decl_processing): Don't use hardwired sizes for the modes when
making int{Q,H,S,D}I_type_mode and the unsigned versions of them; the
actual size depends on BITS_PER_UNIT.
From-SVN: r2836
(pushdecl): Internally generated vars can be
detected with DECL_SOURCE_LINE of zero, not DECL_IGNORED_P.
(start_enum): Push obstacks, switch to permanent if global.
(finish_enum): Pop obstacks.
(store_parm_decls): When clearing ->names, clear out the values
from the identifiers, restore shadowed values, and clear ->shadowed.
(grokdeclarator): Don't warn of const or volatile function
in a system header file.
(start_struct): Push the obstacks.
Switch to permanent if at top level.
(finish_struct): Pop them.
(store_parm_decls): If we have (erroneously) a prototype
and old-style parm decls, throw away the old-style parm decls.
(finish_decl): Do the pop_obstacks sooner, when it's
time to start allocating in the ambient context's obstack.
Don't call permanent_allocation unless got back to permanent obstack.
(explicit_flag_signed_bitfields): New variable.
(c_decode_option): Set that for -f[un]signed-bitfields.
(grokdeclarator): If that's set, and -fsigned-bitfields,
disregard -traditional when handling bitfield signedness.
From-SVN: r2332
(pushdecl): Check an extern decl against both previous global and
previous limbo declarations. For global declarations, clear limbo
value field. For block level extern declarations, set limbo field
if zero.
(grokdeclarator): If this is a block level extern, then allocate
it on the permanent obstack, not the temporary obstack.
From-SVN: r2128
(current_block): New function.
(struct binding_level): New field this_block.
(poplevel): Use this_block if nonzero, rather than making new BLOCK.
(insert_block, delete_block): New functions.
From-SVN: r1958
(finish_struct): If bit field is of an unsigned
type that promotes to int, promote it unsigned if traditional
or if it is the same size as int.
(start_function): Ditto for function return value.
(finish_function): Test only can_reach_end for the warning
about reaching the end of a non-void function.
(poplevel): If apparently nested inline function has
DECL_ABSTRACT_ORIGIN, don't output it; propagate TREE_ADDRESSABLE.
(pushdecl): When copying inline details into an extern decl,
copy DECL_RESULT, TREE_ASM_WRITTEN. Set DECL_ABSTRACT_ORIGIN.
From-SVN: r1781
But don't warn if function definition follows a declaration.
(pushdecl): Don't handle it here.
(grokparms): Don't warn about non-prototype decl in system header.
