From ed874f87e037a1e30643c84c3b5bcaaf8caa0d8c Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 29 Mar 2005 19:30:46 +0000 Subject: [PATCH] gas/testsuite/ 2005-03-29 H.J. Lu * gas/i386/i386.exp: Run segment and inval-seg for i386. Run x86-64-segment and x86-64-inval-seg for x86-64. * gas/i386/intel.d: Expect movw for moving between memory and segment register. * gas/i386/naked.d: Likewise. * gas/i386/opcode.d: Likewise. * gas/i386/x86-64-opcode.d: Likewise. * gas/i386/opcode.s: Use movw for moving between memory and segment register. * gas/i386/x86-64-opcode.s: Likewise. * : Likewise. * gas/i386/inval-seg.l: New. * gas/i386/inval-seg.s: New. * gas/i386/segment.l: New. * gas/i386/segment.s: New. * gas/i386/x86-64-inval-seg.l: New. * gas/i386/x86-64-inval-seg.s: New. * gas/i386/x86-64-segment.l: New. * gas/i386/x86-64-segment.s: New. include/opcode/ 2005-03-29 H.J. Lu * i386.h (i386_optab): Don't allow the `l' suffix for moving moving between memory and segment register. Allow movq for moving between general-purpose register and segment register. opcodes/ 2005-03-29 H.J. Lu * i386-dis.c (SEG_Fixup): New. (Sv): New.
