* Revert r160254 temporarily.Chandler Carruth2012-07-161-10/+12
| | | | | | | | | | | | It turns out that ASan relied on the at-the-end block insertion order to (purely by happenstance) disable some LLVM optimizations, which in turn start firing when the ordering is made more "normal". These optimizations in turn merge many of the instrumentation reporting calls which breaks the return address based error reporting in ASan. We're looking at several different options for fixing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160256 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach AddressSanitizer to create basic blocks in a more natural order.Chandler Carruth2012-07-161-12/+10
| | | | | | | | | This is particularly useful to the backend code generators which try to process things in the incoming function order. Also, cleanup some uses of IRBuilder to be a bit simpler and more clear. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160254 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | functionality test. In general, unless the functionality is substantially separated, we should lump more basic testing into this file. The test running infrastructure likes having a few test files with more comprehensive testing within them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160253 91177308-0d34-0410-b5e6-96231b3b80d8

* [tsan] two more compile-time optimizations:Kostya Serebryany2012-04-101-0/+61
| | | | | | | | | | | | | | | | - don't isntrument reads from constant globals. Saves ~1.5% of instrumented instructions on CPU2006 (counting static instructions, not their execution). - don't insrument reads from vtable (which is a global constant too). Saves ~5%. I did not measure the run-time impact of this, but it is certainly non-negative. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154444 91177308-0d34-0410-b5e6-96231b3b80d8
