From 2ad5709f00b91860c204e1556eb917d42984d40d Mon Sep 17 00:00:00 2001 From: Fred Fish Date: Fri, 16 Feb 1996 22:14:47 +0000 Subject: * bcache.c, bcache.h: New files to implement a byte cache. * Makefile.in (SFILES): Add bcache.c. (symtab_h): Add bcache.h. (HFILES_NO_SRCDIR): add bcache.h (COMMON_OBJS): Add bcache.o (bcache.o): New target. * dbxread.c (start_psymtab): Make global_syms & static_syms type "partial_symbol **". * hpread.c (hpread_start_symtab): Ditto. * os9kread.c (os9k_start_psymtab): Ditto. * stabsread.h (start_psymtab): Ditto. * {symfile.c, symfile.h} (start_psymtab_common): Ditto. * maint.c (maintenance_print_statistics): Call print_symbol_bcache_statistics. * objfiles.c (allocate_objfile): Initialize psymbol bcache malloc and free pointers. * solib.c (allocate_rt_common_objfile): Ditto. * symfile.c (reread_symbols): Ditto. (free_objfile): Free psymbol bcache when objfile is freed. (objfile_relocate): Use new indirect psymbol pointers. * objfiles.h (struct objfile): Add psymbol cache. * symfile.c (compare_psymbols): Now passed pointers to pointers to psymbols. (reread_symbols): Free psymbol bcache when freeing other objfile resources. (add_psymbol_to_list, add_psymbol_addr_to_list): Initialize new psymbol using the psymbol bcache. (init_psymbol_list): Psymbol lists now contain pointers rather than the actual psymbols. * symfile.h (psymbol_allocation_list): Psymbol lists now dynamically grown arrays of pointers. (ADD_PSYMBOL_VT_TO_LIST): Initialize new symbol using the psymbol bcache. * symmisc.c (print_partial_symbols): Now takes pointer to pointer to partial symbol. (print_symbol_bcache_statistics): New function to print per objfile bcache statistics. (print_partial_symbol, print_partial_symbols, maintenance_check_symtabs, extend_psymbol_list): Account for change to pointer to pointer to partial symbol. * symtab.c (find_pc_psymbol, lookup_partial_symbol, decode_line_2, make_symbol_completion_list): Account for change to pointer to pointer to partial symbol. * symtab.h (bcache.h): Include. * xcoffread.c (xcoff_start_psymtab): Make global_syms & static_syms type "partial_symbol **". --- gdb/objfiles.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) (limited to 'gdb/objfiles.c') diff --git a/gdb/objfiles.c b/gdb/objfiles.c index e486550..ed9f1cf 100644 --- a/gdb/objfiles.c +++ b/gdb/objfiles.c @@ -159,6 +159,8 @@ allocate_objfile (abfd, mapped) objfile -> md = md; objfile -> mmfd = fd; /* Update pointers to functions to *our* copies */ + obstack_chunkfun (&objfile -> psymbol_cache.cache, xmmalloc); + obstack_freefun (&objfile -> psymbol_cache.cache, mfree); obstack_chunkfun (&objfile -> psymbol_obstack, xmmalloc); obstack_freefun (&objfile -> psymbol_obstack, mfree); obstack_chunkfun (&objfile -> symbol_obstack, xmmalloc); @@ -186,6 +188,9 @@ allocate_objfile (abfd, mapped) objfile -> mmfd = fd; objfile -> flags |= OBJF_MAPPED; mmalloc_setkey (objfile -> md, 0, objfile); + obstack_specify_allocation_with_arg (&objfile -> psymbol_cache.cache, + 0, 0, xmmalloc, mfree, + objfile -> md); obstack_specify_allocation_with_arg (&objfile -> psymbol_obstack, 0, 0, xmmalloc, mfree, objfile -> md); @@ -228,6 +233,8 @@ allocate_objfile (abfd, mapped) objfile = (struct objfile *) xmalloc (sizeof (struct objfile)); memset (objfile, 0, sizeof (struct objfile)); objfile -> md = NULL; + obstack_specify_allocation (&objfile -> psymbol_cache.cache, 0, 0, + xmalloc, free); obstack_specify_allocation (&objfile -> psymbol_obstack, 0, 0, xmalloc, free); obstack_specify_allocation (&objfile -> symbol_obstack, 0, 0, xmalloc, @@ -433,6 +440,7 @@ free_objfile (objfile) if (objfile->static_psymbols.list) mfree (objfile->md, objfile->static_psymbols.list); /* Free the obstacks for non-reusable objfiles */ + obstack_free (&objfile -> psymbol_cache.cache, 0); obstack_free (&objfile -> psymbol_obstack, 0); obstack_free (&objfile -> symbol_obstack, 0); obstack_free (&objfile -> type_obstack, 0); @@ -552,18 +560,18 @@ objfile_relocate (objfile, new_offsets) } { - struct partial_symbol *psym; + struct partial_symbol **psym; for (psym = objfile->global_psymbols.list; psym < objfile->global_psymbols.next; psym++) - if (SYMBOL_SECTION (psym) >= 0) - SYMBOL_VALUE_ADDRESS (psym) += ANOFFSET (delta, SYMBOL_SECTION (psym)); + if (SYMBOL_SECTION (*psym) >= 0) + SYMBOL_VALUE_ADDRESS (*psym) += ANOFFSET (delta, SYMBOL_SECTION (*psym)); for (psym = objfile->static_psymbols.list; psym < objfile->static_psymbols.next; psym++) - if (SYMBOL_SECTION (psym) >= 0) - SYMBOL_VALUE_ADDRESS (psym) += ANOFFSET (delta, SYMBOL_SECTION (psym)); + if (SYMBOL_SECTION (*psym) >= 0) + SYMBOL_VALUE_ADDRESS (*psym) += ANOFFSET (delta, SYMBOL_SECTION (*psym)); } { -- cgit v1.1
