From 39c0a33100862ba819871baddf47164c1db5e9bb Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Sat, 9 Jun 2001 05:24:39 +0000 Subject: [PATCH] 2001-06-08 H.J. Lu * config/tc-mips.c (warn_nops): New variable. Set to 0 to disable warning about all NOPS that the assembler generates. (macro): Warn NOPS generated only if warn_nops is not 0. (md_shortopts): Add `n'. (md_parse_option): Set warn_nops to 1 for `n'. --- gas/ChangeLog | 8 ++++++++ gas/config/tc-mips.c | 17 ++++++++++++++--- 2 files changed, 22 insertions(+), 3 deletions(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index ae2cd9c5508..6e2ad004c4e 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,11 @@ +2001-06-08 H.J.
