From a86343512845c9c1fdbac865fea88aa5fce7142a Mon Sep 17 00:00:00 2001 From: Eric Christopher Date: Wed, 17 Apr 2019 02:12:23 +0000 Subject: Temporarily Revert "Add basic loop fusion pass." As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546 --- .../exit-block-dominates-rt-check-block.ll | 38 ---------------------- 1 file changed, 38 deletions(-) delete mode 100644 llvm/test/Transforms/LoopVersioning/exit-block-dominates-rt-check-block.ll (limited to 'llvm/test/Transforms/LoopVersioning/exit-block-dominates-rt-check-block.ll') diff --git a/llvm/test/Transforms/LoopVersioning/exit-block-dominates-rt-check-block.ll b/llvm/test/Transforms/LoopVersioning/exit-block-dominates-rt-check-block.ll deleted file mode 100644 index 960c890516c..00000000000 --- a/llvm/test/Transforms/LoopVersioning/exit-block-dominates-rt-check-block.ll +++ /dev/null @@ -1,38 +0,0 @@ -; This test ensures loop versioning does not produce an invalid dominator tree -; if the exit block of the loop (bb0) dominates the runtime check block -; (bb1 will become the runtime check block). - -; RUN: opt -loop-distribute -enable-loop-distribute -verify-dom-info -S -o - %s > %t -; RUN: opt -loop-simplify -loop-distribute -enable-loop-distribute -verify-dom-info -S -o - %s > %t -; RUN: FileCheck --check-prefix CHECK-VERSIONING -input-file %t %s - -; RUN: opt -loop-versioning -verify-dom-info -S -o - %s > %t -; RUN: opt -loop-simplify -loop-versioning -verify-dom-info -S -o - %s > %t -; RUN: FileCheck --check-prefix CHECK-VERSIONING -input-file %t %s - -@c1 = external global i16 - -define void @f(i16 %a) { - br label %bb0 - -bb0: - br label %bb1 - -bb1: - %tmp1 = load i16, i16* @c1 - br label %bb2 - -bb2: - %tmp2 = phi i16 [ %tmp1, %bb1 ], [ %tmp3, %bb2 ] - %tmp4 = getelementptr inbounds [1 x i32], [1 x i32]* undef, i32 0, i32 4 - store i32 1, i32* %tmp4 - %tmp5 = getelementptr inbounds [1 x i32], [1 x i32]* undef, i32 0, i32 9 - store i32 0, i32* %tmp5 - %tmp3 = add i16 %tmp2, 1 - store i16 %tmp2, i16* @c1 - %tmp6 = icmp sle i16 %tmp3, 0 - br i1 %tmp6, label %bb2, label %bb0 -} - -; Simple check to make sure loop versioning happened. -; CHECK-VERSIONING: bb2.lver.check: -- cgit v1.2.3
