Paul Eggert ed253cd8 2014-11-05T11:41:57 obstack: do not reject malloc-style obstack_chunkfun, obstack_freefun Problem reported by Alan Modra in: http://lists.gnu.org/archive/html/bug-gnulib/2014-11/msg00007.html * lib/obstack.h (obstack_chunkfun, obstack_freefun): Always cast the function arg, reverting this part of the previous change.
Paul Eggert 127ed6a3 2014-11-04T00:31:31 obstack: avoid potentially-nonportable function casts * lib/obstack.c (CALL_CHUNKFUN, CALL_FREEFUN): Remove, replacing with ... (call_chunkfun, call_freefun): New static functions. All uses changed. Avoid potentially-nonportable casts. (chunkfun_type, freefun_type): Remove typedefs; no longer used. (_obstack_begin_worker): Omit last two args, since they rely on potentially-nonportable casts. All callers changed. * lib/obstack.h (_OBSTACK_CAST): New macro. Use it everywhere the old API used a potentially-nonportable cast. The new API doesn't cast. (struct obstack): Use unions rather than requiring potentially-nonportable casts. (obstack_chunkfun, obstack_freefun): Return void.
Alan Modra d15b2da0 2014-11-03T17:32:27 obstack: fix macro return values * lib/obstack.h (obstack_next_free): Return void *. (obstack_1grow_fast, obstack_blank_fast): Return void. For __GNUC__ macros: (obstack_1grow, obstack_blank): Remove now unnecessary (void) 0. For !__GNUC__ macros: (obstack_make_room, obstack_grow, obstack_grow0) (obstack_ptr_grow_fast, obstack_int_grow_fast): Return void.
Paul Eggert 6c34297a 2014-10-28T23:58:42 obstack: use size_t alignments and check for overflow * lib/obstack.c, lib/obstack.h (_obstack_begin, _obstack_begin_1): * lib/obstack.c (_obstack_begin_worker, _obstack_newchunk): * lib/obstack.h (struct obstack.alignment_mask): Use _OBSTACK_SIZE_T, not int, for alignments. * lib/obstack.c (_obstack_newchunk): Fail if the size calculation overflows, e.g., when adding the alignment.
Alan Modra 82a38a0d 2014-10-29T14:03:00 obstack: 64-bit obstack support, part 3 This finally enables full 64-bit obstack support. The glibc shared library specific code is removed from obstack.c too, and the error handling code conditionally compiled under control of another macro, _OBSTACK_NO_ERROR_HANDLER. * lib/obstack.h: Include string.h earlier. (_OBSTACK_INTERFACE_VERSION): Define. (_OBSTACK_SIZE_T, _CHUNK_SIZE_T): Define as size_t for version 2. * lib/obstack.c: Don't include shlib-compat.h. (OBSTACK_INTERFACE_VERSION): Delete. (_OBSTACK_ELIDE_CODE): Rename from ELIDE_CODE. Define when version 1 glibc code is compatible with version 2. Don't include stdio.h for __GNU_LIBRARY. (obstack_exit_failure, print_and_abort, obstack_alloc_failed_handler): Omit when _OBSTACK_NO_ERROR_HANDLER defined. Include stdio.h here. (_obstack_compat, _obstack, _obstack_newchunk, obstack_free): Delete glibc shared library specific source.
Alan Modra bb2ab7ec 2014-10-29T14:02:40 obstack: 64-bit obstack support, part 2 This gets us 4G obstack support, without changing ABI compatibility, apart from possibly introducing some signed/unsigned comparison warnings in code that uses obstack.h. a) Replace "int" size parameters, return values, and macro local vars with _OBSTACK_SIZE_T, an "unsigned int" for now. b) Make obstack.chunk_size a _CHUNK_SIZE_T, an "unsigned long" for now. c) Make all obstack macros checking available room use obstack_room. "next_free + desired > chunk_limit" may wrap the lhs for chunks allocated near the top of memory. d) Use unsigned comparisons, and macro locals to support >2G on 32-bit. * lib/obstack.h (_OBSTACK_SIZE_T): Define. Use throughout in place of "int" size parameters, return values and local vars. (_CHUNK_SIZE_T): Define. (struct obstack): Make chunk_size a _CHUNK_SIZE_T. Make temp union use an _OBSTACK_SIZE_T integer type. For __GNUC__ versions of the following macros... (obstack_room): Rename local var. (obstack_make_room): Use obstack_room. (obstack_grow, obstack_grow0, obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank): Likewise. (obstack_finish): Use unsigned comparison when comparing aligned next_free against chunk_limit. (obstack_free): Cast OBJ to remove possible const qualifier. For !__GNUC__ versions of the following macros... (obstack_make_room): Use obstack_room. (obstack_grow, obstack_grow0, obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank): Likewise. (obstack_finish): Use unsigned comparision when comparing aligned next_free against chunk_limit. (obstack_free): Use temp.p and same comparisons as __GNUC__ version. * lib/obstack.c (_obstack_begin_worker): Make "size" parameter _OBSTACK_SIZE_T. (_obstack_begin, _obstack_begin_1): Likewise. (_obstack_newchunk): Likewise for length parameter. Use size_t locals. (_obstack_memory_used): Return and use _OBSTACK_SIZE_T local.
Alan Modra 266ac1b9 2014-10-29T14:02:31 obstack: 64-bit obstack support, part 1 a) Correct calls to alloc function, to use a size_t arg. "long" is just wrong on targets like x86_64-mingw64 where "long" is 32 bits and "size_t" 64 bits. b) Consolidate _obstack_begin and _obstack_begin1 code. * lib/obstack.h (struct obstack <chunkfun>): Correct prototype to use "size_t" rather than "long". (_obstack_begin, _obstack_begin1): Likewise. (obstack_init, obstack_begin, obstack_specify_allocation_with_arg, obstack_chunkfun): Update alloc function casts. * lib/obstack.c (CALL_CHUNKFUN): Update chunkfun cast. (chunkfun_type, freefun_type): New typdefs. (_obstack_begin_worker): Split out from .. (_obstack_begin, _obstack_begin_1): ..here.
Alan Modra 8216dffc 2014-10-29T14:02:22 obstack: tidy part 2 a) Don't be concerned about "not polluting the namespace with stddef.h symbols" in obstack.h, since gnulib string.h includes stddef.h anyway, and it seems unlikely that anyone would care. b) Don't roll our own slow memcpy in _obstack_newchunk. c) Rename obstack_free to _obstack_free. This makes the naming consistent with other obstack functions and obviates the need for __obstack_free. Ancient obstack.c defined both obstack_free and _obstack_free. We continue to do that for _LIBC via an alias. d) Miscellaneous macro fixes. The expression used to test for gcc-2.8 is clever, but nowadays gcc warns on undefined macros. You'll get an undefined macro warning if simulating an old gcc with -U__GNUC__ -U__GNUC_MINOR__ -D__GNUC__=1. * lib/obstack.h: Include stddef.h unconditionally. Formatting fixes. (PTR_INT_TYPE): Delete, replace with ptrdiff_t. (__obstack_free): Delete, update refs. (_obstack_free): Rename from obstack_free. (__extension__): Avoid undefined macro warning for __GNUC_MINOR__. (obstack_object_size, obstack_room): Parenthesise !__GNUC__ versions. * lib/obstack.c: Don't include stddef.h. (COPYING_UNIT): Delete. (_obstack_begin): Formatting fix. (_obstack_newchunk): Use memcpy to move existing object to new chunk. (_obstack_free): Rename from __obstack_free, update alias. Move undef of obstack_free to where it is needed.
Alan Modra ec1a9f7b 2014-10-29T14:02:13 obstack: tidy part 1 a) Rename temp fields. temp.tempint and temp.tempptr just looks ugly to me, and result in overlong lines after later patches. b) Move error handling code, to avoid a forward declaration and to simplify later patches in this series. * lib/obstack.h (struct obstack <temp>): Rename fields of union and update all uses. * lib/obstack.c: Include stdlib.h earlier. (obstack_exit_failure, obstack_alloc_failed_handler): Move later in file. (print_and_abort): Remove now redundant forward declaration.
Paul Eggert 6421fd46 2014-03-27T13:38:41 obstack: Remove ancient NeXTSTEP gcc support conditional This change will ease merging with glibc. The "#if ... __NEXT__" causes a warning with -Wundef which glibc now enables by default. Problem reported by Will Newton in <http://lists.gnu.org/archive/html/bug-gnulib/2014-03/msg00032.html>. glibc <sys/cdefs.h> now uses __extension__ for GCC 2.8 or later, so go with that. * lib/obstack.h (__extension__):
Paul Eggert df9b7142 2014-03-27T12:55:07 obstack: merge with glibc changes * lib/obstack.c, lib/obstack.h: Merge from glibc. This is mostly indenting and commentary changes. Instances of 'register' have been removed.

Paul Eggert 9c5dea9a 2013-10-31T09:44:44 obstack: pacify HP C * lib/obstack.h (obstack_free) [!__GNUC__]: Rewrite to avoid warning "conversion from pointer to smaller integer" from HP C-ANSI-C - cc version B9007AA/B3910B A.06.26. It's safe to assume C89 or later nowadays, so cast to void instead of int. Privately reported by H.Merijn Brand. Also, change header to match glibc's, to make checking against glibc easier.
Jim Meyering c2b08ae2 2013-09-30T10:19:38 fpending, obstack, strerror-override: use pure+const function attrs * lib/fpending.h (__fpending): Declare with the "pure" attribute. * lib/obstack.c (_obstack_allocated_p): Likewise. * lib/obstack.h (_obstack_memory_used): Likewise. (_obstack_memory_used): Likewise. * lib/strerror-override.h (strerror_override): Declare with the "const" attribute.
Paul Eggert 45a46d96 2013-05-15T00:27:15 obstack: port --enable-gcc-warnings to clang * lib/obstack.h (obstack_ptr_grow_fast, obstack_int_grow_fast): Avoid casts from looser to stricter-aligned pointers.

Paul Eggert a4d796fb 2012-02-05T13:42:03 maint: spelling fixes
Paul Eggert c5230ae4 2012-01-25T11:08:01 obstack: remove __STDC__ conditionals * lib/obstack.h: Remove __STDC__ conditionals, as suggested by Joseph S. Myers in <http://cygwin.com/ml/libc-alpha/2012-01/msg00104.html>. This leaves lib/localcharset.c, m4/iconv.m4, and a confusing comment in m4/include_next.m4 as the only gnulib-maintained places that still refer to __STDC__.
