From: Ken Raeburn Date: Tue, 6 Jul 1993 20:20:31 +0000 (+0000) Subject: Stricter prototyping, to force type conversions between 64-bit target and X-Git-Tag: gdb-4_18~18483 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=70e009144e6781fe959c58dbea9e3803ca25cbe4;p=external%2Fbinutils.git Stricter prototyping, to force type conversions between 64-bit target and 32-bit host values. * libbfd.c (bfd_xmalloc_by_size_t): New function. * opncls.c (bfd_cache_init, bfd_open_file): Add prototypes to declarations. (obstack_chunk_alloc): Use bfd_xmalloc_by_size_t. (new_bfd): Prototype-style definition, using DEFUN. (bfd_alloc_grow, bfd_alloc, bfd_zalloc, bfd_realloc): Size argument is type size_t, not bfd_size_type. * ieee.c (obstack_chunk_alloc): Use bfd_xmalloc_by_size_t. * bfd.c (bfd_default_error_trap, bfd_error_trap, bfd_error_nonrepresentabltrap): Prototypes. * libbfd-in.h (bfd_alloc, bfd_zalloc, bfd_realloc, bfd_alloc_grow): Adjusted prototypes for arg type change. * archive.c (get_elt_at_filepos, do_slurp_bsd_armap, normalize, do_slurp_coff_armap, bfd_construct_extended_name_table): Prototypes. --- diff --git a/bfd/bfd.c b/bfd/bfd.c index 53dee5d..89d74f7 100644 --- a/bfd/bfd.c +++ b/bfd/bfd.c @@ -157,6 +157,7 @@ CODE_FRAGMENT . struct trad_core_struct *trad_core_data; . struct hppa_data_struct *hppa_data; . struct hppa_core_struct *hppa_core_data; +. struct sgi_core_struct *sgi_core_data; .
