Move global FlagSfi variables to common module

2013-10-30T12:16:42Z

When built as nexe, llc is configured and built for one arch only. Variables FlagSfiData, FlagSfiLoad, FlagSfiStore, FlagSfiStack, and FlagSfiBranch have to availabe for MIPS as well, so this change moves them from ARM-only code to common code.

Cherry-pick r192124 from upstream. Original commit message: Author: Akira Hatanaka Date: Mon Oct 7 19:13:53 2013 +0000 [mips] Disable tail merging when long branch pass is enabled. Another bug-fix in LongBranchPass, exposed in llc when it is compiled with LLVM, and visible in NativeClient through llc.nexe. TBR= mseaborn@chromium.org, dschuff@chromium.org BUG= bug in llc.nexe for MIPS Review URL: https://codereview.chromium.org/26963003

Apply upstream: [mips] Define method MipsSubtarget::enableLongBranchPass.

Cherry-pick r192122 from upstream. Original commit message: Author: Akira Hatanaka Date: Mon Oct 7 19:06:57 2013 +0000 [mips] Define method MipsSubtarget::enableLongBranchPass. This is a helper function/change for a subsequent fix in LongBranchPass, so we need to cherrypick it to be able to pick the next change as is.

Apply upstream: [mips] Fix a bug in MipsLongBranch::replaceBranch

2013-10-11T01:35:47Z

Cherry-pick r191978 from upstream. Original commit message: Author: Akira Hatanaka Date: Fri Oct 4 20:51:40 2013 +0000 [mips] Fix a bug in MipsLongBranch::replaceBranch, which was erasing instructions in delay slots along with the original branch instructions This has to be cherrypicked, as it is a bug in backend. It was exposed in a long function inside of llc, which caused llc.nexe to work incorrectly.

Cherry-pick r187244 from upstream. Original commit message: Author: Akira Hatanaka 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

[MIPS] Define PnaclTargetArchitectureMips_32

LowerNaClTargetArch has to return const PnaclTargetArchitectureMips_32 for MIPS. The constant is later used in ResolvePNaClIntrinsics pass. BUG= https://code.google.com/p/nativeclient/issues/detail?id=3602 R=jfb@chromium.org Review URL: https://codereview.chromium.org/25887007

[MIPS] Fix LLVM merge issues

2013-07-24T00:42:25Z

Several parts of the already in-place code have been omitted in the previous merge. These are: - missing lowering of Intrinsic::nacl_read_tp; - checks for forbidden instructiosn in branch-delay slots; - lowering operation for ISD::NACL_TP_TLS_OFFSET and ISD::NACL_TP_TDB_OFFSET.
