2013-10-11Apply upstream: [mips] Implement llvm.trap intrinsic.Petar Jovanovic
Cherry-pick r187244 from upstream. Original commit message: Author: Akira Hatanaka <ahatanaka@mips.com> Date: Fri Jul 26 20:58:55 2013 +0000 [mips] Implement llvm.trap intrinsic. Patch by Sasa Stankovic. This has to be cherrypicked, as two tests fail due to missing llvm.trap intrinsic. The tests are: - run_sysbrk_test - run_abi_types_test TBR= mseaborn@chromium.org, dschuff@chromium.org BUG= sysbrk and abi_types tests fail for MIPS Review URL: https://codereview.chromium.org/26953003

Several parts of the already in-place code have been omitted in the previous merge.

2013-04-11[MIPS] Fix LLVM issues with recent LLVM trunk mergePetar Jovanovic
This change fixes some of the issues that came with recent merge with LLVM trunk, and it removes some workarounds that are not needed anymore in the code. In more details, it: - removes hack to set ELF::EF_MIPS_PIC flag; - checks whether __nacl_read_tp is defined in the module, as different relocation(s) is used to calculate the address; - marks Mips::JALRPseudo as indirect call in NaCl rewrite pass; - fixes incorrect merge in MipsAsmPrinter.cpp and MipsMCTargetDesc.cpp. BUG= https://code.google.com/p/nativeclient/issues/detail?id=2275 TEST= run smoke tests Review URL: https://codereview.chromium.org/13601014

The target has a native instruction that maps to ISD::FSINCOS node or the target provides a sincos library call. Implemented the generic optimization in sdisel and enabled it for Mac OSX.
