* instcombine: Migrate math library call simplificationsMeador Inge2012-11-131-1/+2
| | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167815 91177308-0d34-0410-b5e6-96231b3b80d8
* Add method for replacing instructions to LibCallSimplifierMeador Inge2012-11-111-1/+10
| | | | | | | | | | | | | | | In some cases the library call simplifier may need to replace instructions other than the library call being simplified. In those cases it may be necessary for clients of the simplifier to override how the replacements are actually done. As such, a new overrideable method for replacing instructions was added to LibCallSimplifier. A new subclass of LibCallSimplifier is also defined which overrides the instruction replacement method. This is because the instruction combiner defines its own replacement method which updates the worklist when instructions are replaced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167681 91177308-0d34-0410-b5e6-96231b3b80d8
* Implement new LibCallSimplifier classMeador Inge2012-10-131-0/+43
This patch implements the new LibCallSimplifier class as outlined in [1]. In addition to providing the new base library simplification infrastructure, all the fortified library call simplifications were moved over to the new infrastructure. The rest of the library simplification optimizations will be moved over with follow up patches. NOTE: The original fortified library call simplifier located in the SimplifyFortifiedLibCalls class was not removed because it is still used by CodeGenPrepare. This class will eventually go away too.
