* clang-cl: With -fmsc-version=1900, use MSVS2015 diag formatting.Nico Weber2016-03-231-1/+9
| | | | | | | | | | | Remove tests that have neither a triple nor an explicit -fmsc-version flag, since in the absence of an -fmsc-version flag, the implicit value of the flag is 17 (MSVC2013) with MSVC triples but 0 (not set) for other triples, and the default triple is platform dependent. This relands r263974 with a test fix. llvm-svn: 264210
* [CUDA] Don't define __NVCC__.Justin Lebar2016-03-231-1/+0
| | | | | | | | | | | | | | | | | | | | | Summary: We decided this makes life too difficult for code authors. For example, people may want to detect NVCC and disable variadic templates, which NVCC does not support, but which we do. Since people are going to have to change compiler flags *anyway* in order to compile with clang, if they really want the old behavior, they can pass -D__NVCC__. Tested with tensorflow and thrust, no apparent problems. Reviewers: tra Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D18417 llvm-svn: 264205

* clang-cl: Fix remaining bugs in interaction of /Yc and /FI /showIncludes.Nico Weber2016-03-232-30/+31
| | | | | | | | | | Instead of putting the /Yc header into ExtraDeps, give DependencyOutputOptions a dedicated field for /Yc mode, and let HeaderIncludesCallback hang on to the full DependencyOutputOptions object, not just ExtraDeps. Reverts parts of r263352 that are now no longer needed. llvm-svn: 264182
* clang-cl: Add more tests for the interaction of /FI and /Yc /Yu.Nico Weber2016-03-231-2/+4
| | | | | | | | | | | | Most things even work; see the included FIXMEs for things that need polishing. Also don't warn about unused flags for the `/Yuh2.h /FIh1.h /FIh2.h`. The common case is that the pch was built with `/Ych2.h /FIh1.h /FIh2.h`, so h1.h is in the PCH, and we shouldn't warn about /FIh1.h not having an effect. (If we wanted to get fancy, we could store the list of -include flags in the pch and then check that it matches later on.) llvm-svn: 264178
* clang-cl: Include /FI headers in /showIncludes output.Nico Weber2016-03-233-9/+16
| | | | | | | | | | | | | | | | | -H in gcc mode doesn't print -include headers, but they are included in depfiles written by MMD and friends. Since /showIncludes is what's used instead of depfiles, printing /FI there seems important (and matches cl.exe). Instead of giving HeaderIncludeGen more options, just switch on ShowAllHeaders in clang-cl mode and let clang::InitializePreprocessor() not put -include flags in the <command line> block. This changes the behavior of -E slightly, and it removes the <command line> flag from the output triggered by setting the obscure CC_PRINT_HEADERS=1 env var to true while running clang. Both of these seem ok to change. http://reviews.llvm.org/D18401 llvm-svn: 264174

* ObjC: Handle boolean fixed type for enum.Manman Ren2016-03-231-1/+4
| | | | | | | | | | | | | Before this commit, we assert failure in ImplicitCastExpr "unheralded conversion to bool". This commit fixes the assertion by using the correct cast type when the fixed type is boolean. This commit also fixes the behavior for Microsoft mode as well, since Obj-C and Microsoft mode share the same code path. rdar://24999533 llvm-svn: 264167

* [Sema] Allow implicit conversions of &overloaded_fn in C.George Burgess IV2016-03-231-11/+20
| | | | | | | | | | | | | | | | | | | | | | | Also includes a minor ``enable_if`` docs update. Currently, our address-of overload machinery will only allow implicit conversions of overloaded functions to void* in C. For example: ``` void f(int) __attribute__((overloadable)); void f(double) __attribute__((overloadable, enable_if(0, ""))); void *fp = f; // OK. This is C and the target is void*. void (*fp2)(void) = f; // Error. This is C, but the target isn't void*. ``` This patch makes the assignment of `fp2` select the `f(int)` overload, rather than emitting an error (N.B. you'll still get a warning about the `fp2` assignment if you use -Wincompatible-pointer-types).

| | | | | | | | | | The range here isn't over references, so using `auto &` here incites a copy. Switching to `auto *` would do, but we might as well list an explicit type for clarity. Found by -Wrange-loop-analysis. llvm-svn: 264071

| | | | | | | | | | | | | | Summary: A checker (will be uploaded after this patch) needs to check implicit casts. Existing generic matcher "has" ignores implicit casts and parenthesized expressions and no specific matcher for matching return value expression preexisted.

| | | | | | | | | | | | IsExact shouldn't be set to true in WeakObjectProfileTy::getBaseInfo when the receiver is a class because having a class as the receiver doesn't guarantee that the Base is exact. This is a follow-up to r263818. rdar://problem/25208167 llvm-svn: 264025

| | | | | | | | | | | | | | This reverts commit r263607. This change caused more objc_retain/objc_release calls in the IR but those are then incorrectly optimized by the ARC optimizer. Work is going to have to be done to ensure the ARC optimizer doesn't optimize user written RR, but that should land before this change. This change will also need to be updated to take account for any changes required to ensure that user written calls to RR are distinct from those inserted by ARC. llvm-svn: 263984

| | | | | | | | | | This patch adds a regular expression to configure suffixes of an included file to check whether it is the "main" include of the current file.

* [Cxx1z] Implement Lambda Capture of *this by Value as [=,*this] (P0018R3)Faisal Vali2016-03-2112-53/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement lambda capture of *this by copy. For e.g.: struct A { int d = 10; auto foo() { return [*this] (auto a) mutable { d+=a; return d; }; } }; auto L = A{}.foo(); // A{}'s lifetime is gone. // Below is still ok, because *this was captured by value. assert(L(10) == 20); assert(L(100) == 120); If the capture was implicit, or [this] (i.e. *this was captured by reference), this code would be otherwise undefined. Implementation Strategy: - amend the parser to accept *this in the lambda introducer - add a new king of capture LCK_StarThis - teach Sema::CheckCXXThisCapture to handle by copy captures of the enclosing object (i.e. *this) - when CheckCXXThisCapture does capture by copy, the corresponding initializer expression for the closure's data member direct-initializes it thus making a copy of '*this'. - in codegen, when assigning to CXXThisValue, if *this was captured by copy, make sure it points to the corresponding field member, and not, unlike when captured by reference, what the field member points to. - mark feature as implemented in svn Much gratitude to Richard Smith for his carefully illuminating reviews! llvm-svn: 263921

* Reapply [2] [VFS] Add 'overlay-relative' field to YAML filesBruno Cardoso Lopes2016-03-203-20/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reapplies r261552 and r263748. Fixed testcase to reapply. The VFS overlay mapping between virtual paths and real paths is done through the 'external-contents' entries in YAML files, which contains hardcoded paths to the real files. When a module compilation crashes, headers are dumped into <name>.cache/vfs directory and are mapped via the <name>.cache/vfs/vfs.yaml. The script generated for reproduction uses -ivfsoverlay pointing to file to gather the mapping between virtual paths and files inside <name>.cache/vfs. Currently, we are only capable of reproducing such crashes in the same machine as they happen, because of the hardcoded paths in 'external-contents'. To be able to reproduce a crash in another machine, this patch introduces a new option in the VFS yaml file called 'overlay-relative'. When it's equal to 'true' it means that the provided path to the YAML file through the -ivfsoverlay option should also be used to prefix the final path for every 'external-contents'. Example, given the invocation snippet "... -ivfsoverlay <name>.cache/vfs/vfs.yaml" and the following entry in the yaml file: "overlay-relative": "true", "roots": [ ... "type": "directory", "name": "/usr/include", "contents": [ { "type": "file", "name": "stdio.h", "external-contents": "/usr/include/stdio.h" }, ... Here, a file manager request for virtual "/usr/include/stdio.h", that will map into real path "/<absolute_path_to>/<name>.cache/vfs/usr/include/stdio.h. This is a useful feature for debugging module crashes in machines other than the one where the error happened.
