* [llvm.py] Implement interface to enhanced disassemblerGregory Szorc2012-03-102-0/+626
| | | | | | | | | | | This requires a C++ change to EDDisassembler's ctor to function properly (the llvm::InitializeAll* functions aren't being called currently and there is no way to call them from Python). Code is partially tested and works well enough for initial commit. There are probably many small bugs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152506 91177308-0d34-0410-b5e6-96231b3b80d8

* Make this transformation slightly less agressive and more correct.Bill Wendling2012-03-102-8/+53
| | | | | | | | | | | | The 'CmpInst::isFalseWhenEqual' function returns 'false' for values other than simply equality. For instance, it returns 'false' for <= or >=. This isn't the correct behavior for this transformation, which is checking for strict equality and non-equality. It was causing the gcc.c-torture/execute/frame-address.c test to fail because it would completely (and incorrectly) optimize a whole function into a 'ret i32 0'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152497 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement a more intelligent way of spilling uses across an invoke boundary.Bill Wendling2012-03-101-32/+82
| | | | | | | | | | | | | | The old way of determine when and where to spill a value that was used inside of a landing pad resulted in spilling that value everywhere and not just at the invoke edge. This algorithm determines which values are used within a landing pad. It then spills those values before the invoke and reloads them before the uses. This should prevent excessive spilling in many cases, e.g. inside of loops. <rdar://problem/10609139> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152486 91177308-0d34-0410-b5e6-96231b3b80d8
