From bd24b33e5782997dfa26b0debf934dd364756982 Mon Sep 17 00:00:00 2001 From: Tom Stellard Date: Wed, 30 Apr 2014 15:31:33 +0000 Subject: R600/SI: Use VALU instructions for copying i1 values We can't use SALU instructions for this since they ignore the EXEC mask and are always executed. This fixes several OpenCV tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207661 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/R600/valu-i1.ll | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 test/CodeGen/R600/valu-i1.ll (limited to 'test') diff --git a/test/CodeGen/R600/valu-i1.ll b/test/CodeGen/R600/valu-i1.ll new file mode 100644 index 0000000000..5d5e3ff63a --- /dev/null +++ b/test/CodeGen/R600/valu-i1.ll @@ -0,0 +1,39 @@ +; RUN: llc < %s -march=r600 -mcpu=SI | FileCheck --check-prefix=SI %s + +; Make sure the i1 values created by the cfg structurizer pass are +; moved using VALU instructions +; SI-NOT: S_MOV_B64 s[{{[0-9]:[0-9]}}], -1 +; SI: V_MOV_B32_e32 v{{[0-9]}}, -1 +define void @test_if(i32 %a, i32 %b, i32 addrspace(1)* %src, i32 addrspace(1)* %dst) { +entry: + switch i32 %a, label %default [ + i32 0, label %case0 + i32 1, label %case1 + ] + +case0: + %arrayidx1 = getelementptr i32 addrspace(1)* %dst, i32 %b + store i32 0, i32 addrspace(1)* %arrayidx1, align 4 + br label %end + +case1: + %arrayidx5 = getelementptr i32 addrspace(1)* %dst, i32 %b + store i32 1, i32 addrspace(1)* %arrayidx5, align 4 + br label %end + +default: + %cmp8 = icmp eq i32 %a, 2 + %arrayidx10 = getelementptr i32 addrspace(1)* %dst, i32 %b + br i1 %cmp8, label %if, label %else + +if: + store i32 2, i32 addrspace(1)* %arrayidx10, align 4 + br label %end + +else: + store i32 3, i32 addrspace(1)* %arrayidx10, align 4 + br label %end + +end: + ret void +} -- cgit v1.2.3
