* [CMake] Use PRIVATE in target_link_libraries for executablesShoaib Meenai2017-12-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently use target_link_libraries without an explicit scope specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables. Dependencies added in this way apply to both the target and its dependencies, i.e. they become part of the executable's link interface and are transitive. Transitive dependencies generally don't make sense for executables, since you wouldn't normally be linking against an executable. This also causes issues for generating install export files when using LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM library dependencies, which are currently added as interface dependencies. If clang is in the distribution components but the LLVM libraries it depends on aren't (which is a perfectly legitimate use case if the LLVM libraries are being built static and there are therefore no run-time dependencies on them), CMake will complain about the LLVM libraries not being in export set when attempting to generate the install export file for clang. This is reasonable behavior on CMake's part, and the right thing is for LLVM's build system to explicitly use PRIVATE dependencies for executables. Unfortunately, CMake doesn't allow you to mix and match the keyword and non-keyword target_link_libraries signatures for a single target; i.e., if a single call to target_link_libraries for a particular target uses one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must also be updated to use those keywords. This means we must do this change in a single shot. I also fully expect to have missed some instances; I tested by enabling all the projects in the monorepo (except dragonegg), and configuring both with and without shared libraries, on both Darwin and Linux, but I'm planning to rely on the buildbots for other configurations (since it should be pretty easy to fix those). Even after this change, we still have a lot of target_link_libraries calls that don't specify a scope keyword, mostly for shared libraries. I'm thinking about addressing those in a follow-up, but that's a separate change IMO.

* Remove autoconf supportChris Bieneman2016-01-261-50/+0
| | | | | | | | | | | | | | | | | Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "This is the way [autoconf] ends Not with a bang but a whimper." -T.S.

| | | | | | | | | | | | | | | | | This is a necessary prerequisite for debugging with modules. The .pcm files become containers that hold the serialized AST which allows us to store debug information in the module file that can be shared by all object files that were built importing the module. This reapplies r230044 with a fixed configure+make build and updated dependencies and testcase requirements.

* Make clang's rewrite engine a core featureAlp Toker2014-07-161-1/+1
| | | | | | | | | | | | | | | The rewrite facility's footprint is small so it's not worth going to these lengths to support disabling at configure time, particularly since key compiler features now depend on it. Meanwhile the Objective-C rewriters have been moved under the ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still potentially worth excluding from lightweight builds. Tests are now passing with any combination of feature flags. The flags historically haven't been tested by LLVM's build servers so caveat emptor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@213171 91177308-0d34-0410-b5e6-96231b3b80d8

* Flush C stdio streams upon process terminationReid Kleckner2014-06-051-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to what can only be described as a CRT bug, stdout and amazingly even stderr are not always flushed upon process termination, especially when the system is under high threading pressure. I have found two repros for this: 1) In lib\Support\Threading.cpp, change sys::Mutex to an std::recursive_mutex and run check-clang. Usually between 30 and 40 tests will fail. 2) Add OutputDebugStrings in code that runs during static initialization and static shutdown. This will sometimes generate similar failures. After a substantial amount of troubleshooting and debugging, I found that I could reproduce this from the command line without running check-clang. Simply make the mutex change described in #1, then manually run the following command many times by running it once, then pressing Up -> Enter very quickly: D:\src\llvm\build\vs2013\Debug\bin\c-index-test.EXE -cursor-at=D:\src\llvm\tools\clang\test\Index\targeted-preamble.h:2:15 D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -include D:\src\llvm\build\vs2013\tools\clang\test\Index\Output\targeted-cursor.c.tmp.h -Xclang -error-on-deserialized-decl=NestedVar1 -Xclang -error-on-deserialized-decl=TopVar | D:\src\llvm\build\vs2013\Debug\bin\FileCheck.EXE D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -check-prefix=PREAMBLE-CURSOR1 Sporadically they will fail, and attaching a debugger to a failed instance indicates that stdin of FileCheck.exe is empty. Note that due to the repro in #2, we can rule out a bug in the STL's mutex implementation, and instead conclude that this is a real flake in the windows test harness. Test Plan: Without patch: Ran check-clang 10 times and saw over 30 Unexpected failures on every run. With patch: Ran check-clang 10 times and saw 0 unexpected failures across all runs.

This is a new mode of migration, where we avoid modifying the original files but we emit temporary files instead. <path> will be used to keep migration process metadata. Currently the temporary files that are produced are put in the system's temp directory but we can put them in the <path> if is necessary. Also introduce new ARC migration functions in libclang whose only purpose, currently, is to accept <path> and provide pairs of original file/transformed file to map from the originals to the files after transformations are applied. Finally introduce the c-arcmt-test utility that exercises the new libclang functions, update arcmt-test, and add tests for the whole process. rdar://9735086. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134844 91177308-0d34-0410-b5e6-96231b3b80d8
