* Fix coding style error.Rui Ueyama2018-02-131-3/+3

* [InstCombine, InstSimplify] (re)move tests, regenerate checks; NFCSanjay Patel2018-02-133-236/+283
| | | | | | | | The InstCombine integer mul test file had tests that belong in InstSimplify (including fmul tests). Move things to where they belong and auto-generate complete checks for everything. llvm-svn: 325037
* [Debugify] Avoid verifier failure on non-definition subprogramsVedant Kumar2018-02-132-2/+8
| | | | | | | | | | If a function doesn't have an exact definition, don't apply debugify metadata as it triggers a DIVerifier failure. The issue is that it's invalid to have DILocations inside a DISubprogram which isn't a definition ("scope points into the type hierarchy!"). llvm-svn: 325036
* [DeadStoreElimination] Salvage debug info from dead instsVedant Kumar2018-02-132-0/+43
| | | | | | | | | | According to `llvm-dwarfdump --statistics` this salvages 43 additional unique source variables in a stage2 build of clang. It increases the size of the .debug_loc section by 0.002% (or 2864 bytes). Differential Revision: https://reviews.llvm.org/D43220 llvm-svn: 325035

| | | | | | | | Relative paths could be returned in some cases, e.g. when relative path is used in compilation arguments. This led to crash when trying to convert the path to URI. llvm-svn: 325029

* Check that Symbol types are trivially destructibleSam Clegg2018-02-132-0/+4
| | | | | | | | | | | | | | This adds an extra level of static safety to our use of placement new to allocate Symbol types. It prevents the accidental addition on a non-trivially-destructible member that could allocate and leak memory. From the spec: Storage occupied by trivially destructible objects may be reused without calling the destructor. Differential Revision: https://reviews.llvm.org/D43244 llvm-svn: 325025

| | | | | | | | | | | | | | | | | | Summary: Pretty straightforward, returning the `WorkingSetSize` of a `PROCESS_MEMORY_COUNTERS` structure. AFAIU, `GetProcessMemoryInfo` is in `kernel32.lib` for Windows 7 and above. Support for earlier Windows versions would require `psapi.lib`, but I don't think those are supported by ASan?

| | | | | | | | | | | | | | | | | | For basic blocks with instructions between the beginning of the block and a call we have to duplicate the instructions before the call in all split blocks and add PHI nodes for uses of the duplicated instructions after the call. Currently, the threshold for the number of instructions before a call is quite low, to keep the impact on binary size low.

* [clangd] Stop exposing Futures from ClangdServer operations.Sam McCall2018-02-139-111/+149
| | | | | | | | | | | | | | | | | | | | Summary: LSP has asynchronous semantics, being able to block on an async operation completing is unneccesary and leads to tighter coupling with the threading. In practice only tests depend on this, so we add a general-purpose "block until idle" function to the scheduler which will work for all operations. To get this working, fix a latent condition-variable bug in ASTWorker, and make AsyncTaskRunner const-correct.
