* [clang][IFS][test] Fixing lit test breakages on macOS due to r374798Puyan Lotfi2019-10-142-3/+3
| | | | | | | Adding the quotes breaks tests because on Darwin the name mangling is prefixed with an underscore. llvm-svn: 374805
* Fix test breakage caused by r374424Lawrence D'Anna2019-10-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The build directory name is based on the test method name, so having two test methods with the same name in the same test file is a problem, even if they're in different test classes. On linux and darwin this conflict can go unnoticed, but windows has different filesystem semantics and it will fail when one process tries to delete files still held open by another. The problem is fixed just by changing the name of one of the test methods.

* [clang][IFS] Escape mangled names so MS ABI doesn't break YAML parsing.Puyan Lotfi2019-10-144-5/+12
| | | | | | | | | | | Microsoft's ABI mangles names differently than Itanium and this breaks the LLVM yaml parser unless the name is escaped in quotes. Quotes are being added to the mangled names of the IFS file generation so that llvm-ifs doesn't break when Windows triples are passed to the driver.

* [llvm-profdata] Weaken "malformed-ptr-to-counter-array.test" to appease arm botsVedant Kumar2019-10-141-3/+1
| | | | | | | | | | | | | | There are a number arm bots failing after r374617 landed, and I'm not sure why. It looks a bit like the error message llvm-profdata is expected to print to stderr isn't flushed. Weaken the test in an attempt to appease the arm bots: if this doesn't work, that means that llvm-profdata is actually *not failing*, and that will be a clear indication that some logic error is actually happening. http://lab.llvm.org:8011/builders/clang-cmake-armv7-global-isel/builds/5604/ llvm-svn: 374792

* Reapply r374743 with a fix for the ocaml bindingJoerg Sonnenberger2019-10-1439-457/+402
| | | | | | | | | | | | | | | | | | | Add a pass to lower is.constant and objectsize intrinsics This pass lowers is.constant and objectsize intrinsics not simplified by earlier constant folding, i.e. if the object given is not constant or if not using the optimized pass chain. The result is recursively simplified and constant conditionals are pruned, so that dead blocks are removed even for -O0. This allows inline asm blocks with operand constraints to work all the time. The new pass replaces the existing lowering in the codegen-prepare pass and fallbacks in SDAG/GlobalISEL and FastISel. The latter now assert on the intrinsics.

* DWARFExpression: Fix/add support for (v4) debug_loc base address selection ↵Pavel Labath2019-10-142-12/+47
| | | | | | | | | | | | | | | | | | | | entries The DWARFExpression is parsing the location lists in about five places. Of those, only one actually had proper support for base address selection entries. Since r374600, llvm has started to produce location expressions with base address selection entries more aggresively, which caused some tests to fail. This patch adds support for these entries to the places which had it missing, fixing the failing tests. It also adds a targeted test for the two of the three fixes, which should continue testing this functionality even if the llvm output changes. I am not aware of a way to write a targeted test for the third fix (DWARFExpression::Evaluate). llvm-svn: 374769

| | | | | | | | | | | | | | | | | | | | | | | from the subtract directly during isel. This prevents isel from emitting a TEST instruction that optimizeCompareInstr will need to remove later. In some of the modified tests, the SUB gets duplicated due to the flags being needed in two places and being clobbered in between. optimizeCompareInstr was able to optimize away the TEST that was using the result of one of them, but optimizeCompareInstr doesn't know to turn SUB into CMP after removing the TEST. It only knows how to turn SUB into CMP if the result was already dead. With this change the TEST never exists, so optimizeCompareInstr doesn't have to remove it. Then it can just turn the SUB into CMP immediately. Fixes PR43649. llvm-svn: 374755
