From ed44fb7a0ddefcc9c14ac81923e6ed43dd2acd60 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Sat, 6 Jun 1998 03:47:33 +0000 Subject: [PATCH] Fri Jun 5 23:42:43 1998 Alan Modra * i386.h (i386_regtab): Remove BaseIndex modifier from esp. * i386.h: Allow `l' suffix on fld, fst, fstp, fcom, fcomp with register operands, because this is a common idiom. Flag them with a warning. Allow illegal faddp, fsubp, fsubrp, fmulp, fdivp, fdivrp because gcc erroneously generates them. Also flag with a warning. * i386.h: Add suffix modifiers to most insns, and tighter operand checks in some cases. Fix a number of UnixWare compatibility issues with float insns. Merge some floating point opcodes, using new FloatMF modifier. (WORD_PREFIX_OPCODE): Rename to DATA_PREFIX_OPCODE for consistency. * i386.h: Change occurence of ShortformW to W|ShortForm. Add IgnoreDataSize where appropriate. --- include/opcode/ChangeLog | 20 + include/opcode/i386.h | 1454 +++++++++++++++++++------------------- 2 files changed, 738 insertions(+), 736 deletions(-) diff --git a/include/opcode/ChangeLog b/include/opcode/ChangeLog index 258f7fcae5b..942fe71e3ba 100644 --- a/include/opcode/ChangeLog +++ b/include/opcode/ChangeLog @@ -1,3 +1,23 @@ +Fri Jun 5 23:42:43 1998 Alan Modra + + * i386.h (i386_regtab): Remove BaseIndex modifier from esp. + + * i386.h: Allow `l' suffix on fld, fst, fstp, fcom, fcomp with + register operands, because this is a common idiom.
