Apply upstream: Add missing ATOMIC_CMP_SWAP case.

2013-10-11T01:20:45Z

Cherry-pick r185186 from upstream. Original commit message: Author: Lang Hames Date: Fri Jun 28 18:36:42 2013 +0000 Add missing case to switch statement - DAGTypeLegalizer::ExpandIntegerResult should expand ATOMIC_CMP_SWAP nodes the same way that it does for ATOMIC_SWAP. Since ATOMIC_LOADs on some targets (e.g. older ARM variants) get legalized to ATOMIC_CMP_SWAPs, the missing case had been causing i64 atomic loads to crash during isel. This has to be cherry-picked, as we have experienced the same bug described in the original message. Missing case caused MIPS 64 atomics to crash.

Add two passes that implement conversions from PNaCl's specific intrinsics

2013-05-28T18:23:28Z

to external function calls during the translation stage (llc). One of the passes is a ModulePass that adds the appropriate function declarations to the module. The other is a FunctionPass that performs the actual call replacement. This split exists because of bitcode streaming. Initially the passes handle the llvm.nacl.{set|long}jmp intrinsics. In the future they may handle additional intrinsics that are part of the PNaCl stable bitcode ABI. This CL also removes the previous approach to handling this conversion (in SelectionDAGBuilder.cpp). That ended up not working - more details in issue 3429. BUG=https://code.google.com/p/nativeclient/issues/detail?id=3429 R=mseaborn@chromium.org Review URL: https://codereview.chromium.org/16047002

Support @llvm.nacl.{set|long}jmp intrinsics by translating them to library calls

2013-05-09T22:16:09Z

This is similar to the way @llvm.{set|long}jmp are handled. The previously defined nacl-specific intrinsics are no longer used and are overridden. For the library call, call setjmp/longjmp without a preceding underscore as these symbols exist in our runtime support code (pnacl/support/setjmp_XXX.S) BUG=https://code.google.com/p/nativeclient/issues/detail?id=3429 R=mseaborn@chromium.org Review URL: https://codereview.chromium.org/14715018
