From a1917c755584d2e5490b191994316ea27414885d Mon Sep 17 00:00:00 2001 From: Kevin Enderby Date: Wed, 27 Oct 2010 02:32:19 +0000 Subject: Tweaks to X86 instructions to allow the 'w' suffix in places it makes sense, when the instruction takes the 16-bit ax register or m16 memory location. These changes to llvm-mc matches what the darwin assembler allows for these instructions. Done differently than in r117031 that caused a valgrind error which was later reverted. llvm-svn: 117433 --- llvm/test/MC/X86/x86-32.s | 48 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) (limited to 'llvm/test') diff --git a/llvm/test/MC/X86/x86-32.s b/llvm/test/MC/X86/x86-32.s index 9bce1a8da29..590f9681c3e 100644 --- a/llvm/test/MC/X86/x86-32.s +++ b/llvm/test/MC/X86/x86-32.s @@ -726,3 +726,51 @@ pshufw $90, %mm4, %mm0 // CHECK: fucomip %st(1), %st(0) // CHECK: encoding: [0xdf,0xe9] fucompi + +// CHECK: fldcw 32493 +// CHECK: encoding: [0xd9,0x2d,0xed,0x7e,0x00,0x00] + fldcww 0x7eed + +// CHECK: fldcw 32493 +// CHECK: encoding: [0xd9,0x2d,0xed,0x7e,0x00,0x00] + fldcw 0x7eed + +// CHECK: fnstcw 32493 +// CHECK: encoding: [0xd9,0x3d,0xed,0x7e,0x00,0x00] + fnstcww 0x7eed + +// CHECK: fnstcw 32493 +// CHECK: encoding: [0xd9,0x3d,0xed,0x7e,0x00,0x00] + fnstcw 0x7eed + +// CHECK: wait +// CHECK: encoding: [0x9b] + fstcww 0x7eed + +// CHECK: wait +// CHECK: encoding: [0x9b] + fstcw 0x7eed + +// CHECK: fnstsw 32493 +// CHECK: encoding: [0xdd,0x3d,0xed,0x7e,0x00,0x00] + fnstsww 0x7eed + +// CHECK: fnstsw 32493 +// CHECK: encoding: [0xdd,0x3d,0xed,0x7e,0x00,0x00] + fnstsw 0x7eed + +// CHECK: wait +// CHECK: encoding: [0x9b] + fstsww 0x7eed + +// CHECK: wait +// CHECK: encoding: [0x9b] + fstsw 0x7eed + +// CHECK: verr 32493 +// CHECK: encoding: [0x0f,0x00,0x25,0xed,0x7e,0x00,0x00] + verrw 0x7eed + +// CHECK: verr 32493 +// CHECK: encoding: [0x0f,0x00,0x25,0xed,0x7e,0x00,0x00] + verr 0x7eed -- cgit v1.2.3
