From 5e8b833707e6d59576d91b23a2c24e596eace60e Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Fri, 7 Jan 2011 04:59:04 +0000 Subject: Add ARM patterns to match EXTRACT_SUBVECTOR nodes. Also fix an off-by-one in SelectionDAGBuilder that was preventing shuffle vectors from being translated to EXTRACT_SUBVECTOR. Patch by Tim Northover. The test changes are needed to keep those spill-q tests from testing aligned spills and restores. If the only aligned stack objects are spill slots, we no longer realign the stack frame. Prior to this patch, an EXTRACT_SUBVECTOR was legalized by loading from the stack, which created an aligned frame index. Now, however, there is nothing except the spill slot in the stack frame, so I added an aligned alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122995 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/ARM/spill-q.ll | 5 ++++- test/CodeGen/Thumb2/thumb2-spill-q.ll | 5 ++++- 2 files changed, 8 insertions(+), 2 deletions(-) (limited to 'test/CodeGen') diff --git a/test/CodeGen/ARM/spill-q.ll b/test/CodeGen/ARM/spill-q.ll index dc83e25..bf4e55c 100644 --- a/test/CodeGen/ARM/spill-q.ll +++ b/test/CodeGen/ARM/spill-q.ll @@ -15,7 +15,10 @@ define void @aaa(%quuz* %this, i8* %block) { ; CHECK: vst1.64 {{.*}}sp, :128 ; CHECK: vld1.64 {{.*}}sp, :128 entry: - %0 = call <4 x float> @llvm.arm.neon.vld1.v4f32(i8* undef, i32 1) nounwind ; <<4 x float>> [#uses=1] + %aligned_vec = alloca <4 x float>, align 16 + %"alloca point" = bitcast i32 0 to i32 + %vecptr = bitcast <4 x float>* %aligned_vec to i8* + %0 = call <4 x float> @llvm.arm.neon.vld1.v4f32(i8* %vecptr, i32 1) nounwind ; <<4 x float>> [#uses=1] store float 6.300000e+01, float* undef, align 4 %1 = call <4 x float> @llvm.arm.neon.vld1.v4f32(i8* undef, i32 1) nounwind ; <<4 x float>> [#uses=1] store float 0.000000e+00, float* undef, align 4 diff --git a/test/CodeGen/Thumb2/thumb2-spill-q.ll b/test/CodeGen/Thumb2/thumb2-spill-q.ll index 0d73fba..d9a0617 100644 --- a/test/CodeGen/Thumb2/thumb2-spill-q.ll +++ b/test/CodeGen/Thumb2/thumb2-spill-q.ll @@ -15,7 +15,10 @@ define void @aaa(%quuz* %this, i8* %block) { ; CHECK: vst1.64 {{.*}}[{{.*}}, :128] ; CHECK: vld1.64 {{.*}}[{{.*}}, :128] entry: - %0 = call <4 x float> @llvm.arm.neon.vld1.v4f32(i8* undef, i32 1) nounwind ; <<4 x float>> [#uses=1] + %aligned_vec = alloca <4 x float>, align 16 + %"alloca point" = bitcast i32 0 to i32 + %vecptr = bitcast <4 x float>* %aligned_vec to i8* + %0 = call <4 x float> @llvm.arm.neon.vld1.v4f32(i8* %vecptr, i32 1) nounwind store float 6.300000e+01, float* undef, align 4 %1 = call <4 x float> @llvm.arm.neon.vld1.v4f32(i8* undef, i32 1) nounwind ; <<4 x float>> [#uses=1] store float 0.000000e+00, float* undef, align 4 -- cgit v1.1
