2012-09-13Introduce the __llvm_gcov_flush function.Bill Wendling
This function writes out the current values of the counters and then resets them. This can be used similarly to the __gcov_flush function to sync the counters when need be. For instance, in a situation where the application doesn't exit. <rdar://problem/12185886> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163757 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-02Rename ANDROIDEABI to Android.Logan Chien
Most of the code guarded with ANDROIDEABI are not ARM-specific, and having no relation with arm-eabi. Thus, it will be more natural to call this environment "Android" instead of "ANDROIDEABI". Note: We are not using ANDROID because several projects are using "-DANDROID" as the conditional compilation flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163087 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-29Make MemoryBuiltins aware of TargetLibraryInfo.Benjamin Kramer
This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162841 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-16Revert r160254 temporarily.Chandler Carruth
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
2012-07-16Teach AddressSanitizer to create basic blocks in a more natural order.Chandler Carruth
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
2012-07-15Move llvm/Support/TypeBuilder.h -> llvm/TypeBuilder.h. This completesChandler Carruth
the move of *Builder classes into the Core library. No uses of this builder in Clang or DragonEgg I could find. If there is a desire to have an IR-building-support library that contains all of these builders, that can be easily added, but currently it seems likely that these add no real overhead to VMCore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160243 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-29Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.hChandler Carruth
This was always part of the VMCore library out of necessity -- it deals entirely in the IR. The .cpp file in fact was already part of the VMCore library. This is just a mechanical move. I've tried to go through and re-apply the coding standard's preferred header sort, but at 40-ish files, I may have gotten some wrong. Please let me know if so. I'll be committing the corresponding updates to Clang and Polly, and Duncan has DragonEgg. Thanks to Bill and Eric for giving the green light for this bit of cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159421 91177308-0d34-0410-b5e6-96231b3b80d8
