* configure.in (AC_PREREQ): Bump to 2.13.
(AC_C_STRINGIZE): Call this instead of using a custom macro.
* gansidecl.h (HAVE_STRINGIZE): Define, if stage2 gcc && __STDC__.
* system.h (HAVE_STRINGIZE): Test this instead of HAVE_CPP_STRINGIFY.
* acconfig.h (HAVE_CPP_STRINGIFY): Delete.
* alpha/xm-vms.h (HAVE_CPP_STRINGIFY): Delete.
(HAVE_STRINGIZE): Define.
From-SVN: r29590
* aclocal.m4 (AC_GCC_C_LONG_DOUBLE): New macro.
* configure.in (AC_GCC_C_LONG_DOUBLE): Call it.
* gansidecl.h (HAVE_LONG_DOUBLE): Define if gcc for stage2.
* ggc-simple.c (HAVE_LONG_DOUBLE): Test before using long double.
From-SVN: r29432
* system.h (const, inline): Move the stage2 handling of these
keywords-as-macros from here...
* gansidecl.h (const, inline): ...to here.
(This became necessary after using `const' in config directory headers,
which get included before system.h does. If we're going to reset these
keywords, we must do so before absolutely any other header file.)
From-SVN: r25626
* gansidecl.h: Allow attribute unused on labels only when we are
version 2.93 or higher. Not all versions of 2.92 have this feature.
* version.c: Bump minor number to 93.
From-SVN: r24577
* c-common.c (decl_attributes): Allow applying attribute `unused'
on a LABEL_DECL.
* c-parse.in (label): Parse attributes after a label, and call
`decl_attributes' to handle them.
* gansidecl.h (ATTRIBUTE_UNUSED_LABEL): Define.
* genrecog.c (OUTPUT_LABEL, write_tree_1, write_tree): When
generating labels, mark them with ATTRIBUTE_UNUSED_LABEL.
* invoke.texi: Note that labels can be marked `unused'.
From-SVN: r24478
* Makefile.in (toplev.o): Depend on $(EXPR_H).
(insn-extract.o, insn-attrtab.o): Depend on toplev.h.
* gansidecl.h: Define ATTRIBUTE_NORETURN.
* genattrtab.c: Have insn-attrtab.c include toplev.h.
* genextract.c: Have insn-extract.c include toplev.h.
* rtl.h: Don't prototype `fatal_insn_not_found' and `fatal_insn'.
* toplev.c: Include expr.h.
(really_sorry, fancy_abort): Remove prototypes.
(set_target_switch): Add argument in prototype.
(vfatal): Mark prototype with ATTRIBUTE_NORETURN.
(v_really_sorry): Likewise.
(print_version, print_single_switch, print_switch_values): Make
static and add prototype arguments.
(decl_printable_name): Add prototype arguments.
(lang_expand_expr_t): New typedef.
(lang_expand_expr): Declare as a lang_expand_expr_t.
(incomplete_decl_finalize_hook): Add prototype argument.
(decl_name): Mark variable `verbosity' with ATTRIBUTE_UNUSED.
(botch): Likewise for variable `s'.
(rest_of_type_compilation): Mark variables `type' and `toplev'
with ATTRIBUTE_UNUSED if none of DBX_DEBUGGING_INFO,
XCOFF_DEBUGGING_INFO or SDB_DEBUGGING_INFO are defined.
(display_help): Make variable `i' an `unsigned long'.
(main): Remove unused parameter `envp'.
Cast assignment to `lang_expand_expr' to a `lang_expand_expr_t'.
Cast -1 when comparing it with a `size_t'.
* toplev.h (fatal, fatal_io_error, pfatal_with_name): Mark
prototype with ATTRIBUTE_NORETURN.
(fatal_insn_not_found, fatal_insn, really_sorry,
push_float_handler, pop_float_handler): Add prototypes.
(fancy_abort): Mark prototype with ATTRIBUTE_NORETURN.
(do_abort, botch): Add prototypes.
From-SVN: r22293
* gansidecl.h (ATTRIBUTE_UNUSED): Use __unused__ not `unused'.
Don't define NULL here. Also, remove all vestiges of autoconf
based checks for bcmp/bcopy/bzero/index/rindex.
* system.h: Immediately after including stdio.h, check for and if
necessary provide a default definition of NULL.
From-SVN: r20814
* gansidecl.h: Check if compiler supports __attribute__. Provide
definitions for ATTRIBUTE_UNUSED and ATTRIBUTE_PRINTF using
__attribute__ when its available. Also provide definitions for
ATTRIBUTE_PRINTF_1, ATTRIBUTE_PRINTF_2 and ATTRIBUTE_PRINTF_3 in
terms of ATTRIBUTE_PRINTF.
* genoutput.c (process_template): Use ATTRIBUTE_UNUSED in place
of __attribute__.
From-SVN: r19019
* aclocal.m4 (GCC_NEED_DECLARATION): Modify macro to accept a
shell variable argument instead of only hard coded functions.
(GCC_NEED_DECLARATIONS): New macro to accept multiple functions.
* configure.in: Collapse multiple calls to AC_CHECK_FUNCS into one
call. Collapse multiple calls to GCC_NEED_DECLARATION into one
call to GCC_NEED_DECLARATIONS (new macro.) Check if we need
declarations for bcopy, bcmp and bzero.
* acconfig.h: Add stubs for bcopy, bcmp and bzero declarations.
* gansidecl.h: If we have bcopy but don't declare it, then do so.
Likewise for bcmp and bzero. Only define macros for bcopy, bcmp,
bzero, index and rindex if they aren't already present.
