2012-03-02Add the Solaris support directory to the header search when using libc++.David Chisnall
Unconditionally define __C99FEATURES__ when using C++ on Solaris. This is a (hopefully temporary) work around for libc++ exposing C99-but-not-C++98 features in C++98 mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151889 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-02Ensure that we instantiate static reference data members of class templatesRichard Smith
early, since their values can be used in constant expressions in C++11. For odr-use checking, the opposite change is required, since references are odr-used whether or not they satisfy the requirements for appearing in a constant expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151881 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-02PR12145: Avoid emitting loads of constexpr variables in contexts where thereRichard Smith
is no odr-use of the variable. Go slightly beyond what the standard requires for variables of reference type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151879 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-02[analyzer diagnostics] Change CompactPathDiagnostic to recursively compact ↵Ted Kremenek
diagnostics in calls into macro pieces. Also fix handling of macros within calls in the HTMLDiagnostics. This also adds a test case for r151774. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151872 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01c/objc: problem originally reported as an objective-c bug.Fariborz Jahanian
But it is in the underlying c part of clang. clang crashes in IRGen when passing an incomplete type argument to variadic function (instead of diagnosing the bug). // rdar://10961370 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151862 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01Teach the analyzer to just ignore CXXBindTemporaryExpr. There's nothing ↵Ted Kremenek
special to do with it, since destructors are represented explicitly in the CFG. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151856 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01Moving tagging of '__experimental_modules_import' IdentifierInfo out ofTed Kremenek
IndentifierTable::get() and into IdentifierTable's constructor. This gets a 0.7% reducing on lexing time for Cocoa.h, and about the same for PCH generation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151854 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01[analyzer] Turn inlining on by default for better testing exposure.Anna Zaks
Fix a test, which was most likely an unintended recursive call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151848 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01Add a flag -fthread-sanitizer.Kostya Serebryany
This flag enables ThreadSanitizer instrumentation committed to llvm as r150423. The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer. This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet committed and it's structure in compiler-rt is not 100% clear. The users manual wil be changed in a separate commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151846 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01Implement "optimization" for lambda-to-block conversion which inlines the ↵Eli Friedman
generated block literal for lambdas which are immediately converted to block pointer type. This simplifies the AST, avoids an unnecessary copy of the lambda and makes it much easier to avoid copying the result onto the heap. Note that this transformation has a substantial semantic effect outside of ARC: it gives the converted lambda lifetime semantics similar to a block literal. With ARC, the effect is much less obvious because the lifetime of blocks is already managed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151797 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-29Allow operator keywords to be #defined in ms-ext mode.Nico Weber
Fixes PR10606. I'm not sure if this is the best way to go about it, but I locally enabled this code path without the msext conditional, and all tests pass, except for test/Preprocessor/cxx_oper_keyword.cpp which explicitly checks that operator keywords can't be redefined. I also parsed chromium/win with a clang with and without this patch. It introduced no new errors, but removes 43 existing errors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151768 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-29[analyzer] Malloc: A pointer might escape through CFContainers APIs,Anna Zaks
funopen, setvbuf. Teach the checker and the engine about these APIs to resolve malloc false positives. As I am adding more of these APIs, it is clear that all this should be factored out into a separate callback (for example, region escapes). Malloc, KeyChainAPI and RetainRelease checkers could all use it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151737 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-29Reapply r151638 and r151641.James Molloy
The bug that was caught by Apple's internal buildbots was valid and also showed another bug in my implementation. These are now fixed, with regression tests added to catch them both (not Darwin-specific). Original log: ==================== Revert r151638 because it causes assertion hit on PCH creation for Cocoa.h Original log: --------------------- Correctly track tags and enum members defined in the prototype of a function, and ensure they are properly scoped. This fixes code such as: enum e {x, y}; int f(enum {y, x} n) { return 0; } This finally fixes PR5464 and PR5477. --------------------- I also reverted r151641 which was enhancement on top of r151638. ==================== git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151712 91177308-0d34-0410-b5e6-96231b3b80d8
