* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-30/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* Fix the remaining TCL-style quotes found in the testsuite. This isChandler Carruth2012-07-021-1/+1
| | | | | | | | | | | | | | | | | another mechanical change accomplished though the power of terrible Perl scripts. I have manually switched some "s to 's to make escaping simpler. While I started this to fix tests that aren't run in all configurations, the massive number of tests is due to a really frustrating fragility of our testing infrastructure: things like 'grep -v', 'not grep', and 'expected failures' can mask broken tests all too easily. Essentially, I'm deeply disturbed that I can change the testsuite so radically without causing any change in results for most platforms. =/ llvm-svn: 159547

where a comparison has a phi input and that phi is a constant. For example, stuff like: Threading edge through bool from 'bb2149' to 'bb2231' with cost: 1, across block: bb2237: ; preds = %bb2231, %bb2149 %tmp2328.rle = phi i32 [ %tmp2232, %bb2231 ], [ %tmp2232439, %bb2149 ] ; <i32> [#uses=2] %done.0 = phi i32 [ %done.2, %bb2231 ], [ 0, %bb2149 ] ; <i32> [#uses=1] %tmp2239 = icmp eq i32 %done.0, 0 ; <i1> [#uses=1] br i1 %tmp2239, label %bb2231, label %bb2327 or bb38.i298: ; preds = %bb33.i295, %bb1693 %tmp39.i296.rle = phi %struct.ibox* [ null, %bb1693 ], [ %tmp39.i296.rle1109, %bb33.i295 ] ; <%struct.ibox*> [#uses=2] %minspan.1.i291.reg2mem.1 = phi i32 [ 32000, %bb1693 ], [ %minspan.0.i288, %bb33.i295 ] ; <i32> [#uses=1] %tmp40.i297 = icmp eq %struct.ibox* %tmp39.i296.rle, null ; <i1> [#uses=1] br i1 %tmp40.i297, label %implfeeds.exit311, label %bb43.i301 This triggers thousands of times in spec. llvm-svn: 50110
