Without this, loop rotate (among many other places) would suddenly stop working in the presence of debug info. I found this looking at loop rotate, and have augmented its tests with a reduction out of a very hot loop in yacr2 where failing to do this rotation costs sometimes more than 10% in runtime performance, perturbing numerous downstream optimizations. This should have no impact on performance without debug info, but the change in performance when debug info is enabled can be extreme. As a consequence (and this how I got to this yak) any profiling of performance problems should be treated with deep suspicion -- they may have been wildly innacurate of debug info was enabled for profiling. =/ Just a heads up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154263 91177308-0d34-0410-b5e6-96231b3b80d8 Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed. 2012-02-16T06:28:33Z Eli Bendersky eli.bendersky@intel.com 2012-02-16T06:28:33Z urn:sha1:0f0c411079cd21bb3a81a1b70bf8c67539a16c22 Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150664 91177308-0d34-0410-b5e6-96231b3b80d8 loop-rotate shouldn't hoist alloca instructions out of a loop.

It covers the common (in fortran) case of postincrement loops. It's a "free" way to expose this type of loop to downstream loop optimizations that bail out on non-canonical loops (getLoopLatch is a heavily used check). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150439 91177308-0d34-0410-b5e6-96231b3b80d8 remove asmparser support for the old getresult instruction, which has been subsumed by extractvalue. 2011-06-17T06:57:15Z Chris Lattner sabre@nondot.org 2011-06-17T06:57:15Z urn:sha1:424545e9509318e56be88021babec26cbfab8cc8 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133247 91177308-0d34-0410-b5e6-96231b3b80d8 Remove support for using "foo" as symbols instead of %"foo".
