(hashtab_obstack_allocate, dummy_obstack_deallocate): Moved to... * utils.c (hashtab_obstack_allocate, dummy_obstack_deallocate): ...here. * gdbtypes.c: Include "hashtab.h". (build_gdbtypes): Remove extra prototype. (struct type_pair, type_pair_hash, type_pair_eq) (create_copied_types_hash, copy_type_recursive): New. * gdbtypes.h: Include "hashtab.h". (TYPE_ZALLOC): New. (create_copied_types_hash, copy_type_recursive): New prototypes. * objfiles.c (free_objfile): Call preserve_values. * symfile.c (reread_symbols): Likewise. (clear_symtab_users): Remove calls to clear_value_history and clear_internalvars. * value.c (clear_value_history, clear_internalvars): Removed. (preserve_one_value, preserve_values): New functions. * value.h (clear_value_history, clear_internalvars): Removed. (preserve_values): New prototype. * tracepoint.c (_initialize_tracepoint): Do not initialize convenience variables here. gdb/doc/ * gdb.texinfo (Files): Remove obsolete bits from the description of "symbol-file". --- gdb/utils.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'gdb/utils.c') diff --git a/gdb/utils.c b/gdb/utils.c index eb870ac..fdebbdc 100644 --- a/gdb/utils.c +++ b/gdb/utils.c @@ -53,6 +53,7 @@ #include "annotate.h" #include "filenames.h" #include "symfile.h" +#include "gdb_obstack.h" #include "inferior.h" /* for signed_pointer_to_address */ @@ -3124,3 +3125,26 @@ align_down (ULONGEST v, int n) gdb_assert (n && (n & (n-1)) == 0); return (v & -n); } + +/* Allocation function for the libiberty hash table which uses an + obstack.
