From e959ac942ff3a56df111351b65c5a88b0ac2b5da Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 10 Mar 2023 11:06:43 +0100 Subject: x86-64: adjust REX-prefix part of SSE2AVX test Before altering how build_modrm_byte() works, arrange for this part of the testcase to actually use distinguishable source and destination register numbers, such that incorrect propagation of, in particular, the high bit encodings (from REX to VEX) can be noticed (in turn specifically assertions [not] triggering in the respective code). --- gas/testsuite/gas/i386/x86-64-sse2avx.d | 44 +++++++++++++++--------------- gas/testsuite/gas/i386/x86-64-sse2avx.s | 48 ++++++++++++++++----------------- 2 files changed, 46 insertions(+), 46 deletions(-) (limited to 'gas') diff --git a/gas/testsuite/gas/i386/x86-64-sse2avx.d b/gas/testsuite/gas/i386/x86-64-sse2avx.d index d0e50c5..ea68c7d 100644 --- a/gas/testsuite/gas/i386/x86-64-sse2avx.d +++ b/gas/testsuite/gas/i386/x86-64-sse2avx.d @@ -713,29 +713,29 @@ Disassembly of section .text: [ ]*[a-f0-9]+: c5 d9 73 d4 64 vpsrlq \$0x64,%xmm4,%xmm4 [ ]*[a-f0-9]+: c5 d9 71 d4 64 vpsrlw \$0x64,%xmm4,%xmm4 [ ]*[a-f0-9]+: c5 f9 c5 cc 64 vpextrw \$0x64,%xmm4,%ecx -[ ]*[a-f0-9]+: c5 f8 58 c0 vaddps %xmm0,%xmm0,%xmm0 -[ ]*[a-f0-9]+: c5 f8 58 04 00 vaddps \(%rax,%rax(,1)?\),%xmm0,%xmm0 -[ ]*[a-f0-9]+: c5 f8 58 c0 vaddps %xmm0,%xmm0,%xmm0 -[ ]*[a-f0-9]+: c5 f8 58 04 00 vaddps \(%rax,%rax(,1)?\),%xmm0,%xmm0 -[ ]*[a-f0-9]+: c5 38 58 c0 vaddps %xmm0,%xmm8,%xmm8 -[ ]*[a-f0-9]+: c5 38 58 04 00 vaddps \(%rax,%rax(,1)?\),%xmm8,%xmm8 -[ ]*[a-f0-9]+: c4 a1 78 58 c0 vaddps %xmm0,%xmm0,%xmm0 -[ ]*[a-f0-9]+: c4 a1 78 58 04 00 vaddps \(%rax,%r8(,1)?\),%xmm0,%xmm0 -[ ]*[a-f0-9]+: c4 c1 78 58 c0 vaddps %xmm8,%xmm0,%xmm0 -[ ]*[a-f0-9]+: c4 c1 78 58 04 00 vaddps \(%r8,%rax(,1)?\),%xmm0,%xmm0 -[ ]*[a-f0-9]+: c5 3a 10 c0 vmovss %xmm0,%xmm8,%xmm8 -[ ]*[a-f0-9]+: c4 c1 7a 10 c0 vmovss %xmm8,%xmm0,%xmm0 -[ ]*[a-f0-9]+: c5 7a 11 c0 vmovss %xmm8,%xmm0,%xmm0 -[ ]*[a-f0-9]+: c4 c1 3a 11 c0 vmovss %xmm0,%xmm8,%xmm8 +[ ]*[a-f0-9]+: c5 f0 58 c8 vaddps %xmm0,%xmm1,%xmm1 +[ ]*[a-f0-9]+: c5 f0 58 0c 00 vaddps \(%rax,%rax(,1)?\),%xmm1,%xmm1 +[ ]*[a-f0-9]+: c5 f0 58 c8 vaddps %xmm0,%xmm1,%xmm1 +[ ]*[a-f0-9]+: c5 f0 58 0c 00 vaddps \(%rax,%rax(,1)?\),%xmm1,%xmm1 +[ ]*[a-f0-9]+: c5 30 58 c8 vaddps %xmm0,%xmm9,%xmm9 +[ ]*[a-f0-9]+: c5 30 58 0c 00 vaddps \(%rax,%rax(,1)?\),%xmm9,%xmm9 +[ ]*[a-f0-9]+: c4 a1 70 58 c8 vaddps %xmm0,%xmm1,%xmm1 +[ ]*[a-f0-9]+: c4 a1 70 58 0c 00 vaddps \(%rax,%r8(,1)?\),%xmm1,%xmm1 +[ ]*[a-f0-9]+: c4 c1 70 58 c8 vaddps %xmm8,%xmm1,%xmm1 +[ ]*[a-f0-9]+: c4 c1 70 58 0c 00 vaddps \(%r8,%rax(,1)?\),%xmm1,%xmm1 +[ ]*[a-f0-9]+: c5 32 10 c8 vmovss %xmm0,%xmm9,%xmm9 +[ ]*[a-f0-9]+: c4 c1 72 10 c8 vmovss %xmm8,%xmm1,%xmm1 +[ ]*[a-f0-9]+: c5 72 11 c1 vmovss %xmm8,%xmm1,%xmm1 +[ ]*[a-f0-9]+: c4 c1 32 11 c1 vmovss %xmm0,%xmm9,%xmm9 [ ]*[a-f0-9]+: c4 c1 39 71 f0 00 vpsllw \$(0x)?0,%xmm8,%xmm8 -[ ]*[a-f0-9]+: c5 79 c5 c0 00 vpextrw \$(0x)?0,%xmm0,%r8d -[ ]*[a-f0-9]+: c4 c1 79 c5 c0 00 vpextrw \$(0x)?0,%xmm8,%eax -[ ]*[a-f0-9]+: c4 63 79 14 c0 00 vpextrb \$(0x)?0,%xmm8,%eax -[ ]*[a-f0-9]+: c4 c3 79 14 c0 00 vpextrb \$(0x)?0,%xmm0,%r8d -[ ]*[a-f0-9]+: c4 63 39 4a c0 00 vblendvps %xmm0,%xmm0,%xmm8,%xmm8 -[ ]*[a-f0-9]+: c4 c3 79 4a c0 00 vblendvps %xmm0,%xmm8,%xmm0,%xmm0 -[ ]*[a-f0-9]+: c4 63 39 4a c0 00 vblendvps %xmm0,%xmm0,%xmm8,%xmm8 -[ ]*[a-f0-9]+: c4 c3 79 4a c0 00 vblendvps %xmm0,%xmm8,%xmm0,%xmm0 +[ ]*[a-f0-9]+: c5 79 c5 c8 00 vpextrw \$(0x)?0,%xmm0,%r9d +[ ]*[a-f0-9]+: c4 c1 79 c5 c8 00 vpextrw \$(0x)?0,%xmm8,%ecx +[ ]*[a-f0-9]+: c4 63 79 14 c1 00 vpextrb \$(0x)?0,%xmm8,%ecx +[ ]*[a-f0-9]+: c4 c3 79 14 c1 00 vpextrb \$(0x)?0,%xmm0,%r9d +[ ]*[a-f0-9]+: c4 63 31 4a c8 00 vblendvps %xmm0,%xmm0,%xmm9,%xmm9 +[ ]*[a-f0-9]+: c4 c3 71 4a c8 00 vblendvps %xmm0,%xmm8,%xmm1,%xmm1 +[ ]*[a-f0-9]+: c4 63 31 4a c8 00 vblendvps %xmm0,%xmm0,%xmm9,%xmm9 +[ ]*[a-f0-9]+: c4 c3 71 4a c8 00 vblendvps %xmm0,%xmm8,%xmm1,%xmm1 [ ]*[a-f0-9]+: c4 e1 fb 2a 00 vcvtsi2sdq \(%rax\),%xmm0,%xmm0 [ ]*[a-f0-9]+: c4 e1 fa 2a 00 vcvtsi2ssq \(%rax\),%xmm0,%xmm0 [ ]*[a-f0-9]+: c4 e3 f9 61 c0 00 vpcmpestriq \$(0x)?0,%xmm0,%xmm0 diff --git a/gas/testsuite/gas/i386/x86-64-sse2avx.s b/gas/testsuite/gas/i386/x86-64-sse2avx.s index 8a45b1e..dda8b7e 100644 --- a/gas/testsuite/gas/i386/x86-64-sse2avx.s +++ b/gas/testsuite/gas/i386/x86-64-sse2avx.s @@ -805,36 +805,36 @@ _start: pextrw $100,%xmm4,%ecx # Tests for REX prefix conversion -
