From 11db99f84731d2c55bd7b055c52fc7168c365e96 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 9 Mar 2005 09:53:50 +0000 Subject: [PATCH] * config/tc-mips.c (MAX_VR4130_NOPS, MAX_DELAY_NOPS): New macros. (MAX_NOPS): Bump to 4. (mips_fix_vr4130): New variable. (nops_for_vr4130): New function. (nops_for_insn): Use MAX_DELAY_NOPS rather than MAX_NOPS. Use nops_for_vr4130 if working around VR4130 errata. (OPTION_FIX_VR4130, OPTION_NO_FIX_VR4130): New macros. (md_longopts): Add -mfix-vr4130 and -mno-fix-vr4130. (md_parse_option): Handle them. (md_show_usage): Print them. * doc/c-mips.texi: Document -mfix-vr4130 and -mno-fix-vr4130. --- gas/doc/c-mips.texi | 4 ++++ gas/testsuite/gas/mips/mips.exp | 1 + 2 files changed, 5 insertions(+) diff --git a/gas/doc/c-mips.texi b/gas/doc/c-mips.texi index b62b7eb2fc6..97469fe2449 100644 --- a/gas/doc/c-mips.texi +++ b/gas/doc/c-mips.texi @@ -129,6 +129,10 @@ Insert nops to work around certain VR4120 errata.
