* [sanitizers] Don't use Windows Trace Logging with Clang in MSVC mode eitherMartin Storsjo2019-03-051-1/+1
| | | | | | | | | | | | | | | The TraceLoggingProvider.h header does work with clang-cl in general these days with Win SDK 10.0.17763.0, but when compiled in 32 bit x86 mode, with the -Z7 flag, compilation fails with the following error: fatal error: error in backend: assembler label '' can not be undefined With older Win SDKs, there are other build failures (regardless of architecture or the -Z7 flag).

* [SCEV] Ensure that isHighCostExpansion takes into account what is being dividedDavid Green2019-03-053-59/+22
| | | | | | | | | | | | | A SCEV is not low-cost just because you can divide it by a power of 2. We need to also check what we are dividing to make sure it too is not a high-code expansion. This helps to not expand the exit value of certain loops, helping not to bloat the code. The change in no-iv-rewrite.ll is reverting back to what it was testing before rL194116, and looks a lot like the other tests in replace-loop-exit-folds.ll.

| | | | | | | | | | | | | | | | | | | Summary: Redecl chains of classes and class templates are not handled well currently. We want to handle them similarly to functions, i.e. try to keep the structure of the original AST as much as possible. The aim is to not squash a prototype with a definition, rather we create both and put them in a redecl chain.

* Make VCRuntime ABI configuration a first-class option.Eric Fiselier2019-03-058-24/+24
| | | | | | | | | | | | | | | | | | | | | | | Summary: On Windows we currently provide two separate ABI configurations. One which defers to `vcruntime` to provide the C++ runtime and another which doesn't. Using `vcruntime` allows interoperability which programs compiled against the MSVC STL, and should be preferred whenever possible. When deferring to `vcruntime` much of the ABI we provide changes. Including the layout of `<stdexcept>` types, their vtables, and how the linkage of their members. This patch introduces the `_LIBCPP_ABI_VCRUNTIME` macro to denote this configuration. It also cleans up the existing configuration for using `vcruntime`. This cleanup lays the groundwork for fixing a number of ABI and interoperability bugs in `<stdexcept>`.

* [X86] Reduce some patterns by using FP instructions for integer types even ↵Craig Topper2019-03-051-61/+9
| | | | | | | | | | | | when AVX2 is available and execution domain fixing will do the right thing We have quite a few cases of using FP instructions for integer operations when only AVX1 is available. Then we switch to integer instructions with AVX2. In a lot of these cases execution domain fixing will take care of turning FP instructions into integer if its profitable. With this patch we just keep on using the FP instructions even with AVX2. I've only handled some cases that don't require messing with patterns that are defined in the instruction definition. Those will require more subtle multiclass work possibly involving null_frag, hasSideEffects = 0, etc. Differential Revision: https://reviews.llvm.org/D58470 llvm-svn: 355361

* [NFC][Sanitizer] Cleanup ASan's GetStackTrace implementationJulian Lettner2019-03-052-19/+19
| | | | | | | | | | | | | | | | | | | | | Cleanup ASan's __sanitizer::BufferedStackTrace::UnwindImpl (formerly GetStackTrace) implementation. Start with ASan because it is the most complex implementation. GetStackTrace implementations seem to have started out as exact copies of the original implementation in ASan, but have diverged in subtle ways. My goal is to parameterize this algorithm (via templating or callbacks) so we can share the implementation and get rid of the inversed dependency (sanitizer_common depends on concrete implementations in asan, ubsan, etc.). This should also help us to avoid those pesky linker errors caused by undefined, duplicate, and weak symbols on Windows.
