From 31751d9d3ef22c725e7122b052ec29118f692ef8 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Tue, 31 Oct 1995 19:16:02 +0000 Subject: [PATCH] * config/tc-ppc.c (md_pseudo_table): Add "bc" and "ec". (ppc_stab_symbol): New static variable. (ppc_change_csect): Check that ppc_toc_csect is not NULL. (ppc_stabx): Set ppc_stab_symbol around call to symbol_make. Set sy_tc.real_name to the stab string. (ppc_bc, ppc_ec): New static functions. (ppc_canonicalize_symbol_name): If ppc_stab_symbol is set, don't do anything. (ppc_symbol_new_hook): If ppc_stab_symbol is set, don't look for a suffix. --- gas/ChangeLog | 11 ++++++++ gas/config/tc-ppc.c | 68 ++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 78 insertions(+), 1 deletion(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index 1924023c64e..79888c9aa3f 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,5 +1,16 @@ Tue Oct 31 13:29:08 1995 Ian Lance Taylor + * config/tc-ppc.c (md_pseudo_table): Add "bc" and "ec". + (ppc_stab_symbol): New static variable. + (ppc_change_csect): Check that ppc_toc_csect is not NULL. + (ppc_stabx): Set ppc_stab_symbol around call to symbol_make.
