* Link libclang with dl if available.Rafael Espindola2015-01-201-0/+5
| | | | | | This is in preparation for changing the link to use -Wl,-z,defs. llvm-svn: 226609
* Fix crashes on missing @interface for categoryBen Langmuir2015-01-205-5/+33
| | | | | | | In a few places we didn't check that Category->getClassInterface() was not null before using it. llvm-svn: 226605
* Add the test that was supposed to be included with r223162.Kaelyn Takata2015-01-201-0/+13
| | | | | | | | | The test case is based on the reduction from PR21679 and has to be freestanding to work correctly, since some of the expected errors (and some of the problems that were fixed) only occur when the end of the file is reached. llvm-svn: 226603
* Implement command line options for stack probe spaceHans Wennborg2015-01-207-2/+62
| | | | | | | | | | | | | This code adds the -mstack-probe-size command line option and implements the /Gs compiler switch for clang-cl. This should fix http://llvm.org/bugs/show_bug.cgi?id=21896 Patch by Andrew H! Differential Revision: http://reviews.llvm.org/D6685 llvm-svn: 226601

| | | | | | | | | | | | | | Before: const char *x = "hello llvm"; After: const char *x = "hello llvm"; This fixes llvm.org/PR22245. Patch by Bill Meltsner, thank you! llvm-svn: 226564
* Re-apply "r226548 - Introduce SPIR calling conventions" reverted in r226558.Alexander Kornienko2015-01-209-4/+64
| | | | | | | | | | | | | | | | | | | | | | | The test was fixed after a discussion with the revision author: the check pattern was made more flexible as the "%call" part is not what we actually want to check strictly there. The original patch description: === Introduce SPIR calling conventions. This implements Section 3.7 from the SPIR 1.2 spec: SPIR kernels should use "spir_kernel" calling convention. Non-kernel functions use "spir_func" calling convention. All other calling conventions are disallowed. The patch works only for OpenCL source. Any other uses will need to ensure that kernels are assigned the spir_kernel calling convention correctly. === llvm-svn: 226561

* [OPENMP] Fixed DSA processing for predetermined shared variables.Alexey Bataev2015-01-202-6/+18

* Make clang-format work in emacs buffers with unicode characters.Manuel Klimek2015-01-191-11/+16
| | | | | | | | | | Emacs functions by default use character positions; convert characters to offsets when handing parameters to clang-format and convert byte offsets we get from clang-format back to character positions. Reworked the code a bit so the 0-based to 1-based offset calculations are done in the same place where we do the multi-byte to offset mapping. llvm-svn: 226445
* Add back a check removed in r226436David Majnemer2015-01-193-2/+17
| | | | | | | It shouldn't have been removed, the code which replaced it didn't cover this case. llvm-svn: 226442

* Sema: Variable definitions cannot be __attribute__((alias))David Majnemer2015-01-196-48/+35
| | | | | | | | | | | | | | | | | | | | Things that are OK: extern int var1 __attribute((alias("v1"))); static int var2 __attribute((alias("v2"))); Things that are not OK: int var3 __attribute((alias("v3"))); extern int var4 __attribute((alias("v4"))) = 4; We choose to accpet: struct S { static int var5 __attribute((alias("v5"))); }; This code causes assertion failues in GCC 4.8 and ICC 13.0.1, we have no reason to reject it. This partially fixes PR22217. llvm-svn: 226436

* Handle unscoped enumeration in nested name specifier.Serge Pavlov2015-01-185-12/+61
| | | | | | | | | | If an unscoped enum is used as a nested name specifier and the language dialect is not C++ 11, issue an extension warning. This fixes PR16951. Differential Revision: http://reviews.llvm.org/D6389 llvm-svn: 226413
* Update error message text.Serge Pavlov2015-01-1810-25/+25
| | | | | | | | | Previously if an enumeration was used in a nested name specifier in pre-C++11 language dialect, error message was 'XXX is not a class, namespace, or scoped enumeration'. This patch removes the word 'scoped' as in C++11 any enumeration may be used in this context. llvm-svn: 226410

* Recommit r225083 (reverted in r225361) now that calls to aggregate ↵David Blaikie2015-01-182-11/+0
| | | | | | | | | | | | | | | | | | | initializers from in class non-static data members are explicitly attributed to the desired line. The code setting the debug location being removed here was accidentally leaking a location into the call to the non-static data member's ctor call. Without it the call had no location and could cause assertion failures if it was inlined. Now that it has a location (and a correct one at that) this code should hopefully be no longer needed. It's possible of course that other parts of the debug info are also relying on the debug locations being set here to leak to where they're needed - so we might see the same assertions again & will have to investigate what the dependence was/is. But the chances are good that any of those are debug info line table quality bugs we've just not found yet anyway - so it'll be good to flush them out. llvm-svn: 226383
* DebugInfo: Correct the debug location of non-static data member initializersDavid Blaikie2015-01-183-9/+8
| | | | | | | | | | This was causing some trouble for otherwise dead code removed in r225085 (reverted in r225361). The location being set for function arguments was leaking out to the call which wasn't setting its own location (so a quality bug turned into a crasher with r225085). Fix this so r225085 can be recommitted. llvm-svn: 226382
* [msan] Fix a uninitialized-use bug in the template argument diffingChandler Carruth2015-01-171-1/+2
| | | | | | | | | | | | | | | | | logic. In one place we would try to check for the difference between integers even if we were missing one of the integers. This would eventually end up reading uninitialized data out of the APSInt objects. The fix is to short circuit the sameness test when we don't have integers on both sides. This fixes a test failure I was seeing with MSan. Not sure whether other bots were seeing it or not, but yay MSan. In particular the feature to very carefully track origins back through stores throughout the program was invaluable. llvm-svn: 226375

* If a function decl cannot be merged, mark it as invalid.Nico Weber2015-01-177-15/+12
| | | | | | | | | | | | | | | | | | | Clang currently crashes on class C { C() = default; C() = delete; }; My cunning plan for fixing this was to change the `if (!FnD)` in Parser::ParseCXXInlineMethodDef() to `if (!FnD || FnD->isInvalidDecl)` – but alas, the second constructor decl wasn't marked as invalid. This lets Sema::MergeFunctionDecl() return true on function redeclarations, which leads to them being marked invalid. This also improves error messages when functions are redeclared. llvm-svn: 226365
