From e5487fce5d85325403b87c13caee443369e6d9e8 Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Tue, 28 Jan 2014 05:32:58 +0000 Subject: Handle spilling the PPC GPRC_NOR0 register class GPRC_NOR0 is not a subclass of GPRC (because it also contains the ZERO pseudo register). As a result, we also need to check for it in the spilling code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200288 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/PowerPC/spill-nor0.ll | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 test/CodeGen/PowerPC/spill-nor0.ll (limited to 'test') diff --git a/test/CodeGen/PowerPC/spill-nor0.ll b/test/CodeGen/PowerPC/spill-nor0.ll new file mode 100644 index 0000000000..65bdc09143 --- /dev/null +++ b/test/CodeGen/PowerPC/spill-nor0.ll @@ -0,0 +1,23 @@ +; RUN: llc < %s -O0 -mcpu=ppc64 | FileCheck %s +target datalayout = "E-m:e-i64:64-n32:64" +target triple = "powerpc64-unknown-linux-gnu" + +; Function Attrs: nounwind +define void @_ZN4llvm3sys17RunningOnValgrindEv() #0 { +entry: + br i1 undef, label %if.then, label %if.end + +if.then: ; preds = %entry + ret void + +if.end: ; preds = %entry + %0 = call i64 asm sideeffect "mr 3,$1\0A\09mr 4,$2\0A\09rotldi 0,0,3 ; rotldi 0,0,13\0A\09rotldi 0,0,61 ; rotldi 0,0,51\0A\09or 1,1,1\0A\09mr $0,3", "=b,b,b,~{cc},~{memory},~{r3},~{r4}"(i32 0, i64* undef) #0 + unreachable + +; CHECK-LABEL: @_ZN4llvm3sys17RunningOnValgrindEv +; CHECK: stw +; CHECK: lwz +} + +attributes #0 = { nounwind } + -- cgit v1.2.3
