From fc7233808a1d88db99a5181e1ee0f6865f8f5206 Mon Sep 17 00:00:00 2001 From: John Gilmore Date: Thu, 2 May 1991 04:11:40 +0000 Subject: Merge devo/bfd with GDB's bfd. Remove obstack.h to ../include and obstack.c to ../libiberty. Move COFF symbol swapping code to coffswap.c where GDB can call it but it won't be duplicated if we have N different COFF targets. Add support for traditional Unix core files (with a upage). This support is from an Ultrix port, but is probably slightly broken now. Improve bfd_release's of obstack'd items on error returns. gcc -Wall fixes. Handle section alignment slightly better in coff, and comment where it needs more work (on page-aligning virtual vs file addresses for DPAGED). Use set_tdata everywhere that tdata is set, to avoid "cast to the left of assignment" problems with some compilers. Move bfd_alloc, bfd_zalloc, bfd_realloc, and bfd_release into libbfd.h (from bfd.h) since they are internal routines. Remove the redundant suffix "_struct" from struct tags. Set symbol count early in file reading, before slurping in the syms, for GDB's use. --- bfd/cache.c | 27 ++++++++++++--------------- 1 file changed, 12 insertions(+), 15 deletions(-) (limited to 'bfd/cache.c') diff --git a/bfd/cache.c b/bfd/cache.c index d1172fb..c3418ea 100644 --- a/bfd/cache.c +++ b/bfd/cache.c @@ -23,13 +23,6 @@ the Free Software Foundation, 675 Mass Ave, Cambridge, MA 02139, USA. */ #include "bfd.h" #include "libbfd.h" -/* These declarations should not be needed; libbfd.h's inclusion should - have handled it. - int fclose(); - int fseek(); -*/ - - /* The maximum number of FDs opened by bfd */ #define BFD_CACHE_MAX_OPEN 10 @@ -38,10 +31,14 @@ static int open_files; static bfd *cache_sentinel; /* Chain of bfds with active fds we've opened */ -static void -bfd_cache_delete(); -bfd *bfd_last_cache; +bfd *bfd_last_cache; /* Zero, or a pointer to the topmost + bfd on the chain.
