Cherry-pick LLVM 187787 to prevent tail calls on x86-32 when not appropriate.

2013-10-11T22:27:57Z

See: http://llvm.org/viewvc/llvm-project?view=revision&revision=187787 The newer version of newlib tickles this x86-32 bug when building the exception handling tests, which don't strip the "tail" attribute. BUG=https://code.google.com/p/nativeclient/issues/detail?id=3702 Waiting on trybots, but it seems to have fixed the minimal reproducer I have: http://chromegw.corp.google.com/i/tryserver.nacl/builders/nacl-toolchain-linux-pnacl-x86_64/builds/922 http://chromegw.corp.google.com/i/tryserver.nacl/builders/nacl-toolchain-linux-pnacl-x86_32/builds/870 http://chromegw.corp.google.com/i/tryserver.nacl/builders/nacl-toolchain-mac-pnacl-x86_32/builds/875 R=jfb@chromium.org Review URL: https://codereview.chromium.org/26538008

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. TBR= mseaborn@chromium.org, dschuff@chromium.org BUG= bug in MIPS backend Review URL: https://codereview.chromium.org/26933005

Apply upstream: [mips] Implement llvm.trap intrinsic.

2013-10-11T01:30:21Z

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

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. TBR= mseaborn@chromium.org, dschuff@chromium.org BUG= crash for MIPS atomics Review URL: https://codereview.chromium.org/26958002

Apply upstream: [mips] Trap on integer division by zero.

2013-10-11T00:58:15Z

Cherry-pick r182306 from upstream. Original commit message: Author: Akira Hatanaka Date: Mon May 20 18:07:43 2013 +0000 [mips] Trap on integer division by zero. By default, a teq instruction is inserted after integer divide. No divide-by-zero checks are performed if option "-mnocheck-zero-division" is used. TBR= mseaborn@chromium.org, dschuff@chromium.org BUG= missing trap for MIPS Review URL: https://codereview.chromium.org/26846007

Work around a gcc 4.6.3 / 4.7 bug.

2013-09-16T19:26:09Z

GCC bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58416 causes the bf64-1.c test to fail in the GCC torture test suite. This provides an upstreamable workaround. Inspection of the LLVM code base showed no other instances of the pattern that triggers the gcc bug. This can also be upstreamed as soon as I can get a working x86-32 upstream build working to verify/test against. In the meantime, we can make one pnacl-fyi bot go green again.
