From f5e771db37bb4c63f81f902a1d21269c4bd45236 Mon Sep 17 00:00:00 2001 From: Cameron Zwarich Date: Fri, 27 May 2011 22:26:04 +0000 Subject: Add a GR32_NOREX_NOSP register class and fix a bug where getMatchingSuperRegClass() was saying that the matching superregister class of GR32_NOREX in GR64_NOREX_NOSP is GR64_NOREX, which drops the NOSP constraint. This fixes PR10032. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132225 91177308-0d34-0410-b5e6-96231b3b80d8 --- .../CodeGen/X86/2011-05-27-CrossClassCoalescing.ll | 41 ++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 test/CodeGen/X86/2011-05-27-CrossClassCoalescing.ll (limited to 'test/CodeGen/X86/2011-05-27-CrossClassCoalescing.ll') diff --git a/test/CodeGen/X86/2011-05-27-CrossClassCoalescing.ll b/test/CodeGen/X86/2011-05-27-CrossClassCoalescing.ll new file mode 100644 index 0000000..c595bba --- /dev/null +++ b/test/CodeGen/X86/2011-05-27-CrossClassCoalescing.ll @@ -0,0 +1,41 @@ +; RUN: llc < %s -verify-coalescing +target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64" +target triple = "x86_64-apple-macosx10.6.0" + +@bit_count = external constant [256 x i32], align 16 + +define fastcc void @unate_intersect() nounwind uwtable ssp { +entry: + br label %for.body + +for.body: ; preds = %entry, %for.inc.i + br label %do.body.i + +do.body.i: ; preds = %do.body.i, %for.body + %exitcond149 = icmp eq i64 undef, undef + br i1 %exitcond149, label %land.lhs.true, label %do.body.i + +land.lhs.true: ; preds = %do.body.i + br label %for.body.i + +for.body.i: ; preds = %for.inc.i, %if.then + %tmp3524.i = phi i32 [ 0, %land.lhs.true ], [ %tmp351.i, %for.inc.i ] + %tmp6.i12 = load i32* undef, align 4 + br i1 undef, label %for.inc.i, label %if.then.i17 + +if.then.i17: ; preds = %for.body.i + %shr.i14 = lshr i32 %tmp6.i12, 8 + %and14.i = and i32 %shr.i14, 255 + %idxprom15.i = zext i32 %and14.i to i64 + %arrayidx16.i = getelementptr inbounds [256 x i32]* @bit_count, i64 0, i64 %idxprom15.i + %tmp17.i15 = load i32* %arrayidx16.i, align 4 + %add.i = add i32 0, %tmp3524.i + %add24.i = add i32 %add.i, %tmp17.i15 + %add31.i = add i32 %add24.i, 0 + %add33.i = add i32 %add31.i, 0 + br label %for.inc.i + +for.inc.i: ; preds = %if.then.i17, %for.body.i + %tmp351.i = phi i32 [ %add33.i, %if.then.i17 ], [ %tmp3524.i, %for.body.i ] + br label %for.body.i +} -- cgit v1.1
