Author: coby Date: Wed Aug 9 14:50:22 2017 New Revision: 310529 URL: http://llvm.org/viewvc/llvm-project?rev=310529&view=rev Log: [X86][Asm] Allow negative immediate to appear before bracketed expression
Currently, only non-negative immediate is allowed prior to a brac expression (memory reference). MASM / GAS does not have any problem cope with the left side of the real line, so we should be able to as well. llvm: D36229 Differential Revision: https://reviews.llvm.org/D36230 Modified: cfe/trunk/test/CodeGen/ms-inline-asm.c Modified: cfe/trunk/test/CodeGen/ms-inline-asm.c URL: http://llvm.org/viewvc/llvm-project/cfe/trunk/test/CodeGen/ms-inline-asm.c?rev=310529&r1=310528&r2=310529&view=diff ============================================================================== --- cfe/trunk/test/CodeGen/ms-inline-asm.c (original) +++ cfe/trunk/test/CodeGen/ms-inline-asm.c Wed Aug 9 14:50:22 2017 @@ -484,13 +484,13 @@ void t37() { __asm mov eax, (4 + 4) * 16 // CHECK: mov eax, $$128 __asm mov eax, 4 + 8 * -16 -// CHECK: mov eax, $$4294967172 +// CHECK: mov eax, $$-124 __asm mov eax, 4 + 16 / -8 // CHECK: mov eax, $$2 __asm mov eax, (16 + 16) / -8 -// CHECK: mov eax, $$4294967292 +// CHECK: mov eax, $$-4 __asm mov eax, ~15 -// CHECK: mov eax, $$4294967280 +// CHECK: mov eax, $$-16 __asm mov eax, 6 ^ 3 // CHECK: mov eax, $$5 // CHECK: "~{eax},~{dirflag},~{fpsr},~{flags}"() @@ -655,6 +655,12 @@ void t45() { // CHECK: call void asm sideeffect inteldialect "mov dr0, eax\0A\09mov dr1, ebx\0A\09mov dr2, ebx\0A\09mov dr3, ecx\0A\09mov dr6, edx\0A\09mov dr7, ecx", "~{dr0},~{dr1},~{dr2},~{dr3},~{dr6},~{dr7},~{dirflag},~{fpsr},~{flags}"() } +void t46() { + // CHECK-LABEL: define void @t46 + __asm add eax, -128[eax] + // CHECK: call void asm sideeffect inteldialect "add eax, $$-128[eax]", "~{eax},~{flags},~{dirflag},~{fpsr},~{flags}"() +} + void dot_operator(){ // CHECK-LABEL: define void @dot_operator __asm { mov eax, 3[ebx]A.b} _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
