Also make sure registers aren't erased twice if the dead def mentions the register twice. This fixes PR12911. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157254 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-22Fix PR12858, a crash due to GVN's PRE not fully removing an instruction from theDuncan Sands
leader table. That's because it wasn't expecting instructions to turn up as leader for a value number that is not its own, but equality propagation could create this situation. One solution is to have the leader table use a WeakVH but this slows down GVN by about 5%. Instead just have equality propagation not add instructions to the leader table, only constants and arguments. In theory this might cause GVN to run more (each time it changes something it runs again) but it doesn't seem to occur enough to cause a slow down. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157251 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-22This patch adds a predicate to existing mips32 and mips64 so that thoseAkira Hatanaka
instruction encodings can be excluded during mips16 processing. This revision fixes the issue raised by Jim Grosbach. bool hasStandardEncoding() const { return !inMips16Mode(); } When micromips is added it will be bool StandardEncoding() const { return !inMips16Mode()&& !inMicroMipsMode(); } No additional testing is needed other than to assure that there is no regression from this patch.

2012-05-21ARM: .end_data_region mismatch in Thumb2.Jim Grosbach
32-bit offset jump tables just use real branch instructions and so aren't marked as data regions. We were still emitting the .end_data_region marker though, which assert()ed. rdar://11499158 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157221 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-21Give a small negative bias to giant edge bundles.Jakob Stoklund Olesen
This helps compile time when the greedy register allocator splits live ranges in giant functions. Without the bias, we would try to grow regions through the giant edge bundles, usually to find out that the region became too big and expensive. If a live range has many uses in blocks near the giant bundle, the small negative bias doesn't make a big difference, and we still consider regions including the giant edge bundle. Giant edge bundles are usually connected to landing pads or indirect branches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157174 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-20Clear kill flags on the fly when joining intervals.Jakob Stoklund Olesen
With physreg joining out of the way, it is easy to recognize the instructions that need their kill flags cleared while testing for interference. This allows us to skip the final scan of all instructions for an 11% speedup of the coalescer pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157169 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-20Emit memcmp directly from the StringMatcherEmitter.Benjamin Kramer
There should be no difference in the resulting binary, given a sufficiently smart compiler. However we already had compiler timeouts on the generated code in Intrinsics.gen, this hopefully makes the lives of slow buildbots a little easier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157161 91177308-0d34-0410-b5e6-96231b3b80d8
