2011-07-15protect some calls to ConvertType when a function info is under constructionChris Lattner
to prevent recursive compilation problems. This fixes a failure of CodeGen/decl.c on x86-32 targets that don't fill in the coerce-to type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135256 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-15Enhance the IR type lowering code to be much smarter about recursively loweringChris Lattner
types. Fore xample, we used to lower: struct bar { int a; }; struct foo { void (*FP)(struct bar); } G; to: %struct.foo = type { {}* } since the function pointer would cause recursive translation of bar and we didn't know if that would get us into trouble. We are now smart enough to know that it is fine, so we get this type instead: %struct.foo = type { void (i32)* } Codegen still needs to be prepared for uncooperative types at any place, which is why I let the maximally uncooperative code sit around for awhile to help shake out the bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135244 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-15Remove warnings of constant operands of logical operators from template ↵Richard Trieu
instantiations. Upon instantiation of template, value-dependent parameters are replaced by equivalent literals, so code like: template<unsigned int A, unsigned int B> struct S { int foo() { int x = A && B; } } will not warn on A && B on every instantiation. This will still warn on other cases inside templates, which will be caught on checking the template definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135222 91177308-0d34-0410-b5e6-96231b3b80d8

also contain declarators. Previously we would accept code like this: template<typename T> struct S { } f() { return 0; } This case now produces a missing ';' diagnostic, since that seems like a much more likely error than an attempt to declare a function or variable in addition to the class template.

2011-07-14[arcmt] Emit an error for unused -autorelease messages.Argyrios Kyrtzidis
An unused autorelease is badness. If we remove it the receiver will likely die immediately while previously it was kept alive by the autorelease pool. This is bad practice in general, so leave it and emit an error to force the user to restructure his code. rdar://9599884 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135193 91177308-0d34-0410-b5e6-96231b3b80d8

subset of the final functionality. C just leaves the function early. C++98 runs through the same code path, but has no changed functionality either. This is a first baby step towards supporting generalized initializer lists. This also removes an aggregate test case that was just plain wrong, assuming that non-aggregates couldn't be initialized with initializer lists in C++11 mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135177 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-14NestedMacroInstantiations -> NestedMacroExpansionsChandler Carruth
This is switches all the interfaces points (and most of the commenst / local variables I saw on my way through) regarding the NestedMacroInstantiations bit. The libclang enums corresponding to this state were renamed, but a legacy enum was added with the old name, and the same value to keep existing clients working. I've added a documentation blurb for it, but let me know if there is a canonical way to document legacy elemenst of the libclang interface. No functionality changed here, even in tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135141 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Update all of the libclang code corresponding to the preprocessorChandler Carruth
MacroInstantiation -> MacroExpansion rename. Internally, everything is switched. Introduce a new cursor kind enum with the new name, but retain the old name as an alias so that we don't break backwards compatibility. Also update the debug printing routine to use 'macro expansions' as its explicitly not guaranteed to be stable, and mechanically switch the test cases over to that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135140 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Move the rest of the preprocessor terminology from 'instantiate' andChandler Carruth
variants to 'expand'. This changed a couple of public APIs, including one public type "MacroInstantiation" which is now "MacroExpansion". The rest of the codebase was updated to reflect this, especially the libclang code. Two of the C++ (and thus easily changed) libclang APIs were updated as well because they pertained directly to the old MacroInstantiation class. No functionality changed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135139 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-14Switch the TokenLexer's terminology from various forms of 'instantiate'Chandler Carruth

2011-07-14Switch the diagnostic messages about macros to use the terms 'expanded'Chandler Carruth
