2010-04-13Teach HasSideEffect about InitListExprs. Not havingChris Lattner
this caused us to codegen dead globals like this: struct foo { int a; int b; }; static struct foo fooarray[] = { {1, 2}, {4}, }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101150 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13make the rewriter add a #ifndef around the #define of __attribute__.Chris Lattner
Without it, there is no reason for a compiler that supports it to emit the dead static globals that the rewriter labels attribute(used). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101149 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Refactor and simplify the computation of implicit conversion sequencesDouglas Gregor
for reference binding. The code attempted to handle both the computation of the ICS and the actual conversion, but the latter is an anachronism: we now use InitializationSequence for that. Sema::CheckReferenceInit is now a static function TryReferenceInit that's only use within overload resolution, and has been simplified slightly. It still needs to be updated per C++ [over.ics.ref], by eliminating more of the lvalue/rvalue checks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101136 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13When returning the result of a call to an object of class type, do notDouglas Gregor
return a NULL expression; return either an error or a proper expression. Fixes PR6078. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101133 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13During referencing binding, only consider conversion functions forDouglas Gregor
direct reference binding when the source and target types are not reference-related. Fixes PR6066. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101132 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Don't try to find a scope corresponding to the search DC for an unfoundJohn McCall

2010-04-12Implement C++ [over.ics.user]p3, which restricts the final conversionDouglas Gregor
from a conversion function template specialization to one of exact match rank. We only know how to test this in C++0x with default function template arguments, but it's also in the C++03 spec. Fixes PR6285. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101089 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Improve source-location information for C++ conversion functions, byDouglas Gregor
copying the type location information from the conversion-type-id into the type location information for the function type. Do something similar for constructors and destructors, by giving their "void" return type source-location information. In all of these cases, we previously left this type-source information uninitialized, which led to various unfortunate crashes. We still aren't tracking good source-location information for the actual names. That's PR6357. John, please check my sanity on this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101088 91177308-0d34-0410-b5e6-96231b3b80d8

in an input file like this: # 42 int x; we were emitting: # <something> int x; (with a space before the int) because we weren't clearing the leading whitespace flag properly after the \n from the directive was handled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101084 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12fix PR6660/6168: emit padding as zeros instead of undef. Because Chris Lattner
trailing fields may not be represented in initializer lists, they are being handled as padding and those fields *must* be zero initialized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101067 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12Implement C++ [temp.local]p4, which specifies how we eliminateDouglas Gregor
name-lookup ambiguities when there are multiple base classes that are all specializations of the same class template. This is part of a general cleanup for ambiguities in template-name lookup. Fixes PR6717. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101065 91177308-0d34-0410-b5e6-96231b3b80d8

sure to introduce them into the current Scope (when we have one) in addition to the DeclContext for the class, so that they can be found by name lookup for inline members of the class. Fixes PR6570. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101047 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12Add another test case for r101029, which verifies that we nowDouglas Gregor
correctly diagnose instantiation of a function parameter with Objective-C class type (since Objective-C classes can't be passed by value). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101031 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Be sure to instantiate the parameters of a function, even when theDouglas Gregor
function's type is (strictly speaking) non-dependent. This ensures that, e.g., default function arguments get instantiated properly. And, since I couldn't resist, collapse the two implementations of function-parameter instantiation into calls to a single, new function (Sema::SubstParmVarDecl), since the two had nearly identical code (and each had bugs the other didn't!). More importantly, factored out the semantic analysis of a parameter declaration into Sema::CheckParameter, which is called both by Sema::ActOnParamDeclarator (when parameters are parsed) and when a parameter is instantiated. Previously, we were missing some Objective-C and address-space checks on instantiated function parameters. Fixes PR6733. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101029 91177308-0d34-0410-b5e6-96231b3b80d8
