* Add an OutPatFrag TableGen classHal Finkel2014-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, it is currently impossible to use a PatFrag as part of an output pattern (the part of the pattern that has instructions in it) in TableGen. Looking at the current implementation, this was clearly intended to work (there is already code in place to expand patterns in the output DAG), but is currently broken by the baked-in type-checking assumption and the order in which the pattern fragments are processed (output pattern fragments need to be processed after the instruction definitions are processed). Fixing this is fairly simple, but requires some way of differentiating output patterns from the existing input patterns. The simplest way to handle this seems to be to create a subclass of PatFrag, and so that's what I've done here. As a simple example, this allows us to write: def crnot : OutPatFrag<(ops node:$in), (CRNOR $in, $in)>; def : Pat<(not i1:$in), (crnot $in)>; which captures the core use case: handling of repeated subexpressions inside of complicated output patterns. This will be used by an upcoming commit to the PowerPC backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202450 91177308-0d34-0410-b5e6-96231b3b80d8

* [x86] Simplify disassembler code slightly.Craig Topper2014-02-26
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202233 91177308-0d34-0410-b5e6-96231b3b80d8
* Stackmaps are used for OSR exits, which is a custom kind of unwinding. ↵Filip Pizlo2014-02-20
| | | | | | | | | | | | | | | | | | | Hence, they should not be marked nounwind. Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind data for that matter), making deoptimization via stackmaps impossible. This changes the stackmap intrinsic to be may-throw, adds a test for exactly the sympton that WebKit saw, and fixes TableGen to handle un-attributed intrinsics. Thanks to atrick and philipreames for reviewing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201826 91177308-0d34-0410-b5e6-96231b3b80d8

* Recommit r201059 and r201060 with hopefully a fix for its original failure.Craig Topper2014-02-10

* LLVM-1163: AAPCS-VFP violation when CPRC allocated to stackOliver Stannard2014-02-07
| | | | | | | | | | | | | | According to the AAPCS, when a CPRC is allocated to the stack, all other VFP registers should be marked as unavailable. I have also modified the rules for allocating non-CPRCs to the stack, to make it more explicit that all GPRs must be made unavailable. I cannot think of a case where the old version would produce incorrect answers, so there is no test for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200970 91177308-0d34-0410-b5e6-96231b3b80d8
