2018-04-20[DAGCombine] (float)((int) f) --> ftrunc (PR36617)Sanjay Patel
This was originally committed at rL328921 and reverted at rL329920 to investigate failures in Chrome. This time I've added to the ReleaseNotes to warn users of the potential of exposing UB and let me repeat that here for more exposure: Optimization of floating-point casts is improved. This may cause surprising results for code that is relying on undefined behavior. Code sanitizers can be used to detect affected patterns such as this: int main() { float x = 4294967296.0f; x = (float)((int)x); printf("junk in the ftrunc: %f\n", x); return 0; } $ clang -O1 ftrunc.c -fsanitize=undefined ; ./a.out ftrunc.c:5:15: runtime error: 4.29497e+09 is outside the range of representable values of type 'int' junk in the ftrunc: 0.000000 Original commit message: fptosi / fptoui round towards zero, and that's the same behavior as ISD::FTRUNC, so replace a pair of casts with the equivalent node. We don't have to account for special cases (NaN, INF) because out-of-range casts are undefined.

2018-03-16[IR] Avoid the need to prefix MS C++ symbols with '\01'Reid Kleckner
Now the Windows mangling modes ('w' and 'x') do not do any mangling for symbols starting with '?'. This means that clang can stop adding the hideous '\01' leading escape. This means LLVM debug logs are less likely to contain ASCII escape characters and it will be easier to copy and paste MS symbol names from IR. Finally. For non-Windows platforms, names starting with '?' still get IR mangling, so once clang stops escaping MS C++ names, we will get extra '_' prefixing on MachO. That's fine, since it is currently impossible to construct a triple that uses the MS C++ ABI in clang and emits macho object files.

2018-03-12Remove the LoopInstSimplify pass (-loop-instsimplify)Vedant Kumar
LoopInstSimplify is unused and untested. Reading through the commit history the pass also seems to have a high maintenance burden. It would be best to retire the pass for now. It should be easy to recover if we need something similar in the future.

Alignment is now conveyed by supplying the align parameter attribute on the destination and/or source of the cpy/move/set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@324265 91177308-0d34-0410-b5e6-96231b3b80d8

2017-12-08[Debugify] Add a pass to test debug info preservationVedant Kumar
The Debugify pass synthesizes debug info for IR. It's paired with a CheckDebugify pass which determines how much of the original debug info is preserved. These passes make it easier to create targeted tests for debug info preservation. Here is the Debugify algorithm: NextLine = 1 for (Instruction &I : M) attach DebugLoc(NextLine++) to I NextVar = 1 for (Instruction &I : M) if (canAttachDebugValue(I)) attach dbg.value(NextVar++) to I The CheckDebugify pass expects contiguous ranges of DILocations and DILocalVariables. If it fails to find all of the expected debug info, it prints a specific error to stderr which can be FileChecked. This was discussed on llvm-dev in the thread: "Passes to add/validate synthetic debug info" Differential Revision: https://reviews.llvm.org/D40512 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@320202 91177308-0d34-0410-b5e6-96231b3b80d8
