2013-02-19[asan] instrument memory accesses with unusual sizesKostya Serebryany
This patch makes asan instrument memory accesses with unusual sizes (e.g. 5 bytes or 10 bytes), e.g. long double or packed structures. Instrumentation is done with two 1-byte checks (first and last bytes) and if the error is found __asan_report_load_n(addr, real_size) or __asan_report_store_n(addr, real_size) is called. Also, call these two new functions in memset/memcpy instrumentation. asan-rt part will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175507 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-17BBVectorize: Fix an invalid reference bugHal Finkel
This fixes PR15289. This bug was introduced (recently) in r175215; collecting all std::vector references for candidate pairs to delete at once is invalid because subsequent lookups in the owning DenseMap could invalidate the references. bugpoint was able to reduce a useful test case. Unfortunately, because whether or not this asserts depends on memory layout, this test case will sometimes appear to produce valid output. Nevertheless, running under valgrind will reveal the error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175397 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-17Fix a conversion from a forward iterator to a reverse iterator inCameron Zwarich
MachineBasicBlock::SplitCriticalEdge.

Multiple successors can be present without any terminator instructions in the case of exception handling with a fallthrough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175383 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-17Add support for updating the LiveIntervals of registers used by 'exotic'Cameron Zwarich
terminators that actually have register uses when splitting critical edges. This commit also introduces a method repairIntervalsInRange() on LiveIntervals, which allows for repairing LiveIntervals in a small range after an arbitrary target hook modifies, inserts, and removes instructions. It's pretty limited right now, but I hope to extend it to support all of the things that are done by the convertToThreeAddress() target hooks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175382 91177308-0d34-0410-b5e6-96231b3b80d8
