From: Keith Seitz Date: Fri, 23 Jan 1998 20:54:35 +0000 (+0000) Subject: * symfile.c: Define two new hooks for symbol reading: "pre_add_symbol_hook" X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=11f91b2bbca1d68abb0f79a6ef6681daf06c4add;p=binutils-gdb.git * symfile.c: Define two new hooks for symbol reading: "pre_add_symbol_hook" and "post_add_symbol_hook". These hooks are called before we begin reading symbols, and after we finish. (generic_load): Use new symbol reading hooks and get rid of compiler warning. * gdbtk.c (gdbtk_init): Add hooks for pre- and post-symbol reading. (gdbtk_pre_add_symbol): New function: the pre-add-symbol hook. (gdbtk_post_add_symbol): New function: the post-add-symbol hook. (find_file_in_dir): New function. Moved the guts of gdb_find_file_command into here to allow its use by others. (gdb_loc): Use find_file_in_dir to return the real path to the file (or "N/A" if we can't find it). * configure.in (TIX_LIB_EXT): Define new variable for those special cases when TCL_SHLIB_SUFFIX is not enough to specify the dependency. * configure: Regenerate. --- diff --git a/gdb/ChangeLog-gdbtk b/gdb/ChangeLog-gdbtk index 55bdd34b1b6..152634d91ab 100644 --- a/gdb/ChangeLog-gdbtk +++ b/gdb/ChangeLog-gdbtk @@ -1,3 +1,23 @@ +Wed Jan 22 10:37:02 1998 Keith Seitz + + * symfile.c: Define two new hooks for symbol reading: "pre_add_symbol_hook" + and "post_add_symbol_hook".
