From 209f437303f75b11e84a791b288e786a6492e45e Mon Sep 17 00:00:00 2001 From: Jim Laskey Date: Tue, 13 Jun 2006 15:22:49 +0000 Subject: [PATCH] My original test case was bogus. Reverting to crasher case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28767 91177308-0d34-0410-b5e6-96231b3b80d8 --- .../2006-06-13-ComputeMaskedBitsCrash.ll | 79 ++++++++----------- 1 file changed, 33 insertions(+), 46 deletions(-) diff --git a/test/CodeGen/Generic/2006-06-13-ComputeMaskedBitsCrash.ll b/test/CodeGen/Generic/2006-06-13-ComputeMaskedBitsCrash.ll index 4b69386d887..5c5a1dc4e29 100644 --- a/test/CodeGen/Generic/2006-06-13-ComputeMaskedBitsCrash.ll +++ b/test/CodeGen/Generic/2006-06-13-ComputeMaskedBitsCrash.ll @@ -1,50 +1,37 @@ ; RUN: llvm-as < %s | llc -fast -uint %test1(uint %tmp1) { - %tmp2 = or uint %tmp1, 2147483648 - %tmp3 = shr uint %tmp2, ubyte 31 - %tmp4 = and uint %tmp3, 2147483648 - %tmp5 = seteq uint %tmp4, 0 - br bool %tmp5, label %cond_true, label %cond_false - -cond_true: - ret uint %tmp1 - -cond_false: + %struct.cl_perfunc_opts = type { ubyte, ubyte, ubyte, ubyte, ubyte, ubyte, ubyte, ubyte, ubyte, ubyte, ubyte, ubyte, int, int, int, int, int, int, int } +%cl_pf_opts = external global %struct.cl_perfunc_opts ; <%struct.cl_perfunc_opts*> [#uses=2] - ret uint %tmp2 -} - - -uint %test2(uint %tmp1) { - %tmp2 = or uint %tmp1, 2147483648 - %tmp3 = cast uint %tmp2 to int - %tmp4 = shr int %tmp3, ubyte 31 - %tmp5 = cast int %tmp4 to uint - %tmp6 = and uint %tmp5, 2147483648 - %tmp7 = seteq uint %tmp6, 0 - br bool %tmp7, label %cond_true, label %cond_false - -cond_true: - ret uint %tmp1 - -cond_false: - - ret uint %tmp2 -} - - -uint %test3(uint %tmp1) { - %tmp2 = or uint %tmp1, 1 - %tmp3 = shl uint %tmp2, ubyte 31 - %tmp4 = and uint %tmp3, 1 - %tmp5 = seteq uint %tmp4, 0 - br bool %tmp5, label %cond_true, label %cond_false - -cond_true: - ret uint %tmp1 - -cond_false: - - ret uint %tmp2 +implementation ; Functions: + +void %set_flags_from_O() { +entry: + %tmp22 = setgt int 0, 0 ; [#uses=1] + br bool %tmp22, label %cond_true23, label %cond_next159 + +cond_true23: ; preds = %entry + %tmp138 = getelementptr %struct.cl_perfunc_opts* %cl_pf_opts, int 0, uint 8 ; [#uses=1] + %tmp138 = cast ubyte* %tmp138 to uint* ; [#uses=2] + %tmp139 = load uint* %tmp138 ; [#uses=1] + %tmp140 = shl uint 1, ubyte 27 ; [#uses=1] + %tmp141 = and uint %tmp140, 134217728 ; [#uses=1] + %tmp142 = and uint %tmp139, 4160749567 ; [#uses=1] + %tmp143 = or uint %tmp142, %tmp141 ; [#uses=1] + store uint %tmp143, uint* %tmp138 + %tmp144 = getelementptr %struct.cl_perfunc_opts* %cl_pf_opts, int 0, uint 8 ; [#uses=1] + %tmp144 = cast ubyte* %tmp144 to uint* ; [#uses=1] + %tmp145 = load uint* %tmp144 ; [#uses=1] + %tmp146 = shl uint %tmp145, ubyte 22 ; [#uses=1] + %tmp147 = shr uint %tmp146, ubyte 31 ; [#uses=1] + %tmp147 = cast uint %tmp147 to ubyte ; [#uses=1] + %tmp148 = seteq ubyte %tmp147, 0 ; [#uses=1] + br bool %tmp148, label %cond_true149, label %cond_next159 + +cond_true149: ; preds = %cond_true23 + %tmp150 = cast ubyte* null to uint* ; [#uses=0] + ret void + +cond_next159: ; preds = %cond_true23, %entry + ret void }
