2017-06-30[objc] Don't require null-check and don't emit memset when result is ignored ↵Kuba Mracek
for struct-returning method calls [compiler-rt part] This fixes an issue with the emission of lifetime markers for struct-returning Obj-C msgSend calls. When the result of a struct-returning call is ignored, the temporary storage is only marked with lifetime markers in one of the two branches of the nil-receiver-check. The check is, however, not required when the result is unused. If we still need to emit the check (due to consumer arguments), let's not emit the memset to zero out the result if it's unused. This fixes a use-after-scope false positive with AddressSanitizer.

2017-06-29[profile] Move __llvm_profile_filename into a separate objectVedant Kumar
Users can specify the path a raw profile is written to by passing -fprofile-instr-generate=<path>, but this functionality broke on Darwin after __llvm_profile_filename was made weak [1], resulting in profiles being written to "default.profraw" even when <path> is specified. The situation is that instrumented programs provide a weak definition of __llvm_profile_filename, which conflicts with a weak redefinition provided by the profiling runtime. The linker appears to pick the 'winning' definition arbitrarily: on Darwin, it usually prefers the larger definition, which is probably why the instrprof-override-filename.c test has been passing. The fix is to move the runtime's definition into a separate object file within the archive. This means that the linker won't "see" the runtime's definition unless the user program has not provided one. I couldn't think of a great way to test this other than to mimic the Darwin failure: use -fprofile-instr-generate=<some-small-path>. Testing: check-{clang,profile}, modified instrprof-override-filename.c.

2017-06-29[scudo] Change aligned alloc functions to be more compliant & perf changesKostya Kortchinsky
Summary: We were not following the `man` documented behaviors for invalid arguments to `memalign` and associated functions. Using `CHECK` for those was a bit extreme, so we relax the behavior to return null pointers as expected when this happens. Adapt the associated test. I am using this change also to change a few more minor performance improvements: - mark as `UNLIKELY` a bunch of unlikely conditions; - the current `CHECK` in `__sanitizer::RoundUpTo` is redundant for us in *all* calls. So I am introducing our own version without said `CHECK`. - change our combined allocator `GetActuallyAllocatedSize`. We already know if the pointer is from the Primary or Secondary, so the `PointerIsMine` check is redundant as well, and costly for the 32-bit Primary. So we get the size by directly using the available Primary functions. Finally, change a `int` to `uptr` to avoid a warning/error when compiling on Android.
