* instcombine: Migrate memcmp optimizationsMeador Inge2012-11-111-35/+0
| | | | | | | This patch migrates the memcmp optimizations from the simplify-libcalls pass into the instcombine library call simplifier. llvm-svn: 167683
* Move "atomic" and "volatile" designations on instructions after the opcodeEli Friedman2011-08-121-11/+11
| | | | | | | | | | of the instruction. Note that this change affects the existing non-atomic load and store instructions; the parser now accepts both forms, and the change is noted in the release notes. llvm-svn: 137527
* Properly promote operands when optimizing a single-character memcmp.Benjamin Kramer2010-05-251-1/+13

* move an optimization for memcmp out of simplifylibcalls and into Chris Lattner2009-12-241-3/+0
| | | | | | | | | SDISel. This optimization was causing simplifylibcalls to introduce type-unsafe nastiness. This is the first step, I'll be expanding the memcmp optimizations shortly, covering things that we really really wouldn't want simplifylibcalls to do. llvm-svn: 92098
* Teach SimplifyLibCalls to fold memcmp calls with constant arguments.Benjamin Kramer2009-11-051-0/+4

* Change tests from "opt %s" to "opt < %s" so that opt doesn't see theDan Gohman2009-09-111-1/+1

* Use opt -S instead of piping bitcode output through llvm-dis.Dan Gohman2009-09-081-1/+1

* Change these tests to feed the assembly files to opt directly, insteadDan Gohman2009-09-081-1/+1

* remove redundant check.Chris Lattner2008-04-301-3/+1

* Remove llvm-upgrade and update tests.Tanya Lattner2008-03-101-18/+18

* For PR1319:Reid Spencer2007-04-161-1/+2
