From 1719a98cf0a0f8eb1167b7eac395db4d11c97a53 Mon Sep 17 00:00:00 2001 From: Simon Pilgrim Date: Thu, 11 Jan 2018 16:57:58 +0000 Subject: [PATCH] [X86][SSE] Drop old insertps stack folding test Broken test from old attempt for folding tables - we don't peek through extract_subvector spills at all (which is why it doesn't fold), and we already have foldMemoryOperandCustom to handle insertps immediate correction anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@322292 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/stack-folding-fp-avx1.ll | 14 -------------- 1 file changed, 14 deletions(-) diff --git a/test/CodeGen/X86/stack-folding-fp-avx1.ll b/test/CodeGen/X86/stack-folding-fp-avx1.ll index 481fb952462..6e2c5de158b 100644 --- a/test/CodeGen/X86/stack-folding-fp-avx1.ll +++ b/test/CodeGen/X86/stack-folding-fp-avx1.ll @@ -1934,19 +1934,5 @@ define <8 x float> @stack_fold_xorps_ymm(<8 x float> %a0, <8 x float> %a1) { ret <8 x float> %6 } -define <4 x float> @stack_nofold_insertps(<8 x float> %a0, <8 x float> %a1) { -; Cannot fold this without changing the immediate. -; CHECK-LABEL: stack_nofold_insertps -; CHECK: 32-byte Spill -; CHECK: nop -; CHECK: 32-byte Reload -; CHECK: vinsertps $179, {{%xmm., %xmm., %xmm.}} - %1 = tail call <2 x i64> asm sideeffect "nop", "=x,~{xmm2},~{xmm3},~{xmm4},~{xmm5},~{xmm6},~{xmm7},~{xmm8},~{xmm9},~{xmm10},~{xmm11},~{xmm12},~{xmm13},~{xmm14},~{xmm15},~{flags}"() - %v0 = shufflevector <8 x float> %a0, <8 x float> undef, <4 x i32> - %v1 = shufflevector <8 x float> %a1, <8 x float> undef, <4 x i32> - %res = call <4 x float> @llvm.x86.sse41.insertps(<4 x float> %v0, <4 x float> %v1, i8 179) - ret <4 x float> %res -} - attributes #0 = { "unsafe-fp-math"="false" } attributes #1 = { "unsafe-fp-math"="true" } -- 2.11.0
