* Thread the determination of branch prediction hit rates back through the ↵Owen Anderson2010-10-011-6/+9
| | | | | | | | | | if-conversion heuristic APIs. For now, stick with a constant estimate of 90% (branch predictors are good!), but we might find that we want to provide more nuanced estimates in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115364 91177308-0d34-0410-b5e6-96231b3b80d8
* Massive rewrite of MMX: Dale Johannesen2010-09-301-167/+143
| | | | | | | | | | | | | | | | | | | | | The x86_mmx type is used for MMX intrinsics, parameters and return values where these use MMX registers, and is also supported in load, store, and bitcast. Only the above operations generate MMX instructions, and optimizations do not operate on or produce MMX intrinsics. MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into smaller pieces. Optimizations may occur on these forms and the result casted back to x86_mmx, provided the result feeds into a previous existing x86_mmx operation. The point of all this is prevent optimizations from introducing MMX operations, which is unsafe due to the EMMS problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115243 91177308-0d34-0410-b5e6-96231b3b80d8
