2011-07-02Make clang behave in a gcc-compatible way in the presence of multiple flags ↵Eli Friedman
for the same x86 target feature (e.g. -mno-sse -msse). gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels.

2011-07-02Move the Sema argument to all of the Sema-using helper functions inChandler Carruth
SemaDeclAttr to the first argument. This makes them follow the very consistent policy elsewhere in Sema for helper functions. Original patch by Caitlin Sadowski, with some tweaking by me. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134290 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-01Mechanical rename of 'd' Decl pointer parameters to 'D'. This is moreChandler Carruth
conventional in the rest of Clang's codebase, and closer to the current style recommendations.

2011-07-01When adding boolean keywords for typo correction, add either "bool" orDouglas Gregor
"_Bool" (depending on dialect), but not both, since they have the same edit distance from "Bool". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134263 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01Don't zero-initialize default-initialized local variables that haveDouglas Gregor
trivial default constructors. This generated-code regression was caused by r131796, which had simplified the handling of default initialization in Sema. Fixes <rdar://problem/9694300>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134260 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01For code such as:Richard Trieu
int f(int x) { if (int foo = f(bar)) {} return 0; } Clang produces the following error messages: paren_imbalance.cc:2:19: error: use of undeclared identifier 'bar' if (int foo = f(bar)) {} ^ paren_imbalance.cc:2:26: error: expected ')' if (int foo = f(bar)) {} ^ paren_imbalance.cc:2:6: note: to match this '(' if (int foo = f(bar)) {} ^ The second error is incorrect. This patch will stop Clang from producing an error on parenthesis imbalance during error recovery when there isn't one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134258 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01Fix for PR7410. Allow functions in a derived class that improperly overwrite ↵Richard Trieu
a virtual function in the base class to be inserted into the derived class function list to prevent extra errors every time the derived class is used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134251 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01Fix AST representations of alias-declarations which define tag types. Inside ↵Richard Smith
classes, the tag types need to have an associated access specifier, and inside function definitions, they need to be included in the declarations of the DeclStmt. These issues manifested as assertions during template instantiation, and also in a WIP constexpr patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134250 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01When we create a precompiled preamble, don't copy theDouglas Gregor
CompilerInvocation on the stack, because other objects (e.g., the CompilerInstance) maintain an intrusive reference-counted pointer to the CompilerInvocation. This doesn't matter in the normal case, because we take back the CompilerInvocation. However, during crash recovery, this leads to us trying to free an object on the stack, and hilarity ensues. Fixes <rdar://problem/9652540>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134245 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01Just mangle substituted template parameter types as unresolved types.John McCall
This is kindof questionable but seems to do more-or-less the right thing. This is not a particularly friendly part of the ABI. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134227 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01Introduce the notion of instantiation dependence into Clang's AST. ADouglas Gregor
type/expression/template argument/etc. is instantiation-dependent if it somehow involves a template parameter, even if it doesn't meet the requirements for the more common kinds of dependence (dependent type, type-dependent expression, value-dependent expression). When we see an instantiation-dependent type, we know we always need to perform substitution into that instantiation-dependent type. This keeps us from short-circuiting evaluation in places where we shouldn't, and lets us properly implement C++0x [temp.type]p2. In theory, this would also allow us to properly mangle instantiation-dependent-but-not-dependent decltype types per the Itanium C++ ABI, but we aren't quite there because we still mangle based on the canonical type in cases like, e.g., template<unsigned> struct A { }; template<typename T> void f(A<sizeof(sizeof(decltype(T() + T())))>) { } template void f<int>(A<sizeof(sizeof(int))>); and therefore get the wrong answer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134225 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-30Fix an obvious typo in an attribute's diagnostics.Chandler Carruth

2011-06-29Introduce a caching mechanism for macro expanded tokens.Argyrios Kyrtzidis
Previously macro expanded tokens were added to Preprocessor's bump allocator and never released, even after the TokenLexer that were lexing them was finished, thus they were wasting memory. A very "useful" boost library was causing clang to eat 1 GB just for the expanded macro tokens. Introduce a special cache that works like a stack; a TokenLexer can add the macro expanded tokens in the cache, and when it finishes, the tokens are removed from the end of the cache. Now consumed memory by expanded tokens for that library is ~ 1.5 MB. Part of rdar://9327049. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134105 91177308-0d34-0410-b5e6-96231b3b80d8
