From 2428e76364be447d59086d06513aa58e3135c91e Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Sun, 7 Jul 2013 10:00:42 +0000 Subject: [PATCH] include/opcode/ * mips.h: Update documentation of "+s" and "+S". opcodes/ * mips-opc.c (mips_builtin_opcodes): Use "+s" for "cins32" and "+S" for "cins". * mips-dis.c (print_mips_arg): Update "+s" and "+S" comments. Combine cases. gas/ * config/tc-mips.c (mips_ip): Preserve the real bit number for "+p". Require the msb to be <= 31 for "+s". Check that the size is <= 31 for both "+s" and "+S". --- include/opcode/ChangeLog | 4 ++++ include/opcode/mips.h | 9 ++++----- 2 files changed, 8 insertions(+), 5 deletions(-) diff --git a/include/opcode/ChangeLog b/include/opcode/ChangeLog index b2b718cb4..b3bee6f36 100644 --- a/include/opcode/ChangeLog +++ b/include/opcode/ChangeLog @@ -1,3 +1,7 @@ +2013-07-07 Richard Sandiford + + * mips.h: Update documentation of "+s" and "+S". + 2013-07-07 Richard Sandiford * mips.h: Document "+i". diff --git a/include/opcode/mips.h b/include/opcode/mips.h index d25b13687..b583a51f4 100644 --- a/include/opcode/mips.h +++ b/include/opcode/mips.h @@ -508,11 +508,10 @@ struct mips_opcode "+P" Position field of cins/exts aliasing cins32/exts32.
