Revert the test moves from 176733. Use "REQUIRES: asserts" instead. llvm-svn: 176873 2013-03-12 17:27:52 +01:00			`; REQUIRES: asserts`
Add new RegionInfo pass. The RegionInfo pass detects single entry single exit regions in a function, where a region is defined as any subgraph that is connected to the remaining graph at only two spots. Furthermore an hierarchical region tree is built. Use it by calling "opt -regions analyze" or "opt -view-regions". llvm-svn: 109089 2010-07-22 09:46:31 +02:00			`; RUN: opt -regions -analyze < %s`
Convert the uses of '\|&' to use '2>&1 \|' instead, which works on old versions of Bash. In addition, I can back out the change to the lit built-in shell test runner to support this. This should fix the majority of fallout on Darwin, but I suspect there will be a few straggling issues. llvm-svn: 159544 2012-07-02 20:37:59 +02:00			`; RUN: opt -regions -stats < %s 2>&1 \| FileCheck -check-prefix=STAT %s`
