* fix unnamed fiefield issue and add tests for __builtin_preserve_access_index ↵Yonghong Song2019-07-152-2/+22
| | | | | | | | | | | | | | | | | | | | intrinsic This is a followup patch for https://reviews.llvm.org/D61809. Handle unnamed bitfield properly and add more test cases. Fixed the unnamed bitfield issue. The unnamed bitfield is ignored by debug info, so we need to ignore such a struct/union member when we try to get the member index in the debug info. D61809 contains two test cases but not enough as it does not checking generated IRs in the fine grain level, and also it does not have semantics checking tests. This patch added unit tests for both code gen and semantics checking for the new intrinsic. Signed-off-by: Yonghong Song <yhs@fb.com> llvm-svn: 366076

* [clang][Driver][ARM] Favor -mfpu over default CPU featuresAlexandros Lamprineas2019-07-141-1/+5
| | | | | | | | | | | | | | | | When processing the command line options march, mcpu and mfpu, we store the implied target features on a vector. The change D62998 introduced a temporary vector, where the processed features get accumulated. When calling DecodeARMFeaturesFromCPU, which sets the default features for the specified CPU, we certainly don't want to override the features that have been explicitly specified on the command line. Therefore, the default features should appear first in the final vector. This problem became evident once I added the missing (unhandled) target features in ARM::getExtensionFeatures.

* [CMake][Fuchsia] Define asan+noexcept multilibPetr Hosek2019-07-131-0/+5
| | | | | | | | | | | | | | | | | | Using noexcept multilib with -fno-exceptions can lead to significant space savings when statically linking libc++abi because we don't need all the unwinding and demangling code. When compiling with ASan, we already get a lot of overhead from the instrumentation itself, when statically linking libc++abi, that overhead is even larger. Having the noexcept variant for ASan can help significantly, we've seen more than 50% size reduction in our system image, which offsets the cost of having to build another multilib.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commands. Summary: It's common to use compiler wrappers by setting CC="gomacc clang++". This results in both args appearing in compile_commands.json, and clang's driver can't handle this. This patch attempts to recognize this pattern (by looking for well-known wrappers) and dropping argv0 in this case. It conservatively ignores other cases for now: - wrappers with unknown names - wrappers that accept -flags - wrappers where the compiler to use is implied (usually cc or gcc) This is done at the JSONCompilationDatabase level rather than somewhere more fundamental, as (hopefully) this isn't a general conceptual problem, but a messy aspect of the nature of the ecosystem around compile_commands.json. i.e. compilation databases more tightly tied to the build system should not have this problem.

This simplifies the logic and fixes PR9825: -fno-omit-frame-pointer doesn't imply -mno-omit-leaf-frame-pointer. and PR24003: /Oy- /O2 should not omit leaf frame pointer: this matches MSVC x86-32. (/Oy- is a no-op on MSVC x86-64.) and: when CC1 option -mdisable-fp-elim if absent, -momit-leaf-frame-pointer can also be omitted. The new behavior matches GCC: -fomit-frame-pointer wins over -mno-omit-leaf-frame-pointer -fno-omit-frame-pointer loses out to -momit-leaf-frame-pointer The behavior makes lots of sense. We have 4 states: - 00) leaf retained, non-leaf retained - 01) leaf retained, non-leaf omitted (this is invalid) - 10) leaf omitted, non-leaf retained (what -momit-leaf-frame-pointer was designed for) - 11) leaf omitted, non-leaf omitted "omit" options taking precedence over "no-omit" options is the only way to make 3 valid states representable with -f(no-)?omit-frame-pointer and -m(no-)?omit-leaf-pointer.
