* [driver][macOS] Link libarclite from the default toolchain when clangAlex Lorenz2019-04-261-1/+30
| | | | | | | | | | | | | | | is running in a toolchain outside of xcode 'libarclite' usually lives in the same toolchain as 'clang'. However, the Swift open source toolchains for macOS distribute Clang without 'libarclite'. In that case, to allow the linker to find 'libarclite', we point to the 'libarclite' that should be in the XcodeDefault toolchain instead. The path to the toolchain is inferred from the SDK path if it's specified. https://bugs.swift.org/browse/SR-9972 rdar://49947573 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@359353 91177308-0d34-0410-b5e6-96231b3b80d8
* [LTO] Add plumbing to save stats during LTO on Darwin.Florian Hahn2019-04-191-0/+8
| | | | | | | | | | | | | | | | | | | | | Gold and ld on Linux already support saving stats, but the infrastructure is missing on Darwin. Unfortunately it seems like the configuration from lib/LTO/LTO.cpp is not used. This patch adds a new LTOStatsFile option and adds plumbing in Clang to use it on Darwin, similar to the way remarks are handled. Currnetly the handling of LTO flags seems quite spread out, with a bunch of duplication. But I am not sure if there is an easy way to improve that?

* Move detection of libc++ include dirs to Driver on MacOSIlya Biryukov2018-12-051-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The intention is to make the tools replaying compilations from 'compile_commands.json' (clang-tidy, clangd, etc.) find the same standard library as the original compiler specified in 'compile_commands.json'. Previously, the library detection logic was in the frontend (InitHeaderSearch.cpp) and relied on the value of resource dir as an approximation of the compiler install dir. The new logic uses the actual compiler install dir and is performed in the driver. This is consistent with the C++ standard library detection on other platforms and allows to override the resource dir in the tools using the compile_commands.json without altering the standard library detection mechanism. The tools have to override the resource dir to make sure they use a consistent version of the builtin headers. There is still logic in InitHeaderSearch that attemps to add the absolute includes for the the C++ standard library, so we keep passing the -stdlib=libc++ from the driver to the frontend via cc1 args to avoid breaking that. In the long run, we should move this logic to the driver too, but it could potentially break the library detection on other systems, so we don't tackle it in this patch to keep its scope manageable. This is a second attempt to fix the issue, first one was commited in r346652 and reverted in r346675. The original fix relied on an ad-hoc propagation (bypassing the cc1 flags) of the install dir from the driver to the frontend's HeaderSearchOptions. Unsurpisingly, the propagation was incomplete, it broke the libc++ detection in clang itself, which caused LLDB tests to break. The LLDB tests pass with new fix.

* Refactor Darwin driver to refer to runtimes by componentChris Bieneman2018-08-151-60/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In r335809, Petr Hosek lays out support for what he calls the multiarch runtimes layout. This new way of laying out the directories for runtime libraries is workable for all platforms. Petr did some of the common infrastructure and made it work for Linux and Fuscia. This patch is a cleanup to the Darwin and MachO drivers to serve as a step toward supporting it in Darwin. This patch does primarily two things: (1) Changes the APIs for how the Darwin driver refers to compiler-rt libraries to use the component names, similar to how Linux and Fuscia do (2) Removes some legacy functionality for supporting macOS versions before 10.6. This functionality is effectively dead code because in r339277, the support was removed from compiler-rt for generating the 10.4 runtime support library, and Xcode 10 (currently in beta) removes libgcc_s.10.4 and libgcc_s.10.5 from the macOS SDK. With this patch landed a subsequent patch can modify MachO::AddLinkRuntimeLib to support the multiarch runtimes layout. Worth noting: None of the removed functionality was actually covered in the test suite. So no test case updates are required.

* [Preprocessor] Allow libc++ to detect when aligned allocation is unavailable.Volodymyr Sapsai2018-08-031-1/+5

This patch implements the following changes: * The `__cpp_aligned_new` feature test macro to no longer be defined when aligned allocation is otherwise enabled but unavailable. * The Darwin driver no longer passes `-faligned-alloc-unavailable` when the user manually specifies `-faligned-allocation` or `-fno-aligned-allocation`. * Instead of a warning Clang now generates a hard error when an aligned allocation or deallocation function is referenced but unavailable.

| | | | | | | | | | | | | | | | | | The simulator variant of Darwin's platforms is removed in favor of a new environment field. The code that selects the platform and the version is split into 4 different functions instead of being all in one function. This is an NFC commit, although it slightly improves the "invalid version number" diagnostic by displaying the environment variable instead of -m<os>-version-min if the OS version was derived from the environment. rdar://35813850 Differential Revision: https://reviews.llvm.org/D41035 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@320235 91177308-0d34-0410-b5e6-96231b3b80d8

* [XRay][darwin] Initial XRay in Darwin SupportDean Michael Berris2017-11-101-0/+6
| | | | | | | | | | | | | | | | | | | | | | Summary: This change implements the changes required in both clang and compiler-rt to allow building XRay-instrumented binaries in Darwin. For now we limit this to x86_64. We also start building the XRay runtime library in compiler-rt for osx. A caveat to this is that we don't have the tests set up and running yet, which we'll do in a set of follow-on changes. This patch uses the monorepo layout for the coordinated change across multiple projects.
