* Revert "Temporarily Revert "Add basic loop fusion pass.""Eric Christopher2019-04-171-0/+99

* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-99/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* AMDGPU: mark ldexp LibCalls as unavailableNicolai Hahnle2015-12-151-10/+9
| | | | | | | | | | | | | | | | | | Summary: The LibCallSimplifier will turn llvm.exp2.* intrinsics into ldexp* libcalls which do not make sense with the AMDGPU backend. In the long run, we'll want an llvm.ldexp.* intrinsic to properly make use of this optimization, but this works around the problem for now. See also: http://reviews.llvm.org/D14327 (suggested llvm.ldexp.* implementation) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92709 Reviewers: arsenm, tstellarAMD Differential Revision: http://reviews.llvm.org/D14990 llvm-svn: 255658

* instcombine: Migrate math library call simplificationsMeador Inge2012-11-131-0/+76
This patch migrates the math library call simplifications from the simplify-libcalls pass into the instcombine library call simplifier. I have typically migrated just one simplifier at a time, but the math simplifiers are interdependent because: 1. CosOpt, PowOpt, and Exp2Opt all depend on UnaryDoubleFPOpt. 2. CosOpt, PowOpt, Exp2Opt, and UnaryDoubleFPOpt all depend on the option -enable-double-float-shrink. These two factors made migrating each of these simplifiers individually more of a pain than it would be worth. So, I migrated them all together. llvm-svn: 167815
