implications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64547 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-14add parser and type checking support for attribute((objc_exception)).Chris Lattner
We don't have "zero cost" exceptions for ObjC yet, so there is no codegen support required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64546 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-14Several related changes: Chris Lattner
1) implement parser and sema support for reading and verifying attribute(warnunusedresult). 2) rename hasLocalSideEffect to isUnusedResultAWarning, inverting the sense of its result. 3) extend isUnusedResultAWarning to directly return the loc and range info that should be reported to the user. Make it substantially more precise in some cases than what was previously reported. 4) teach isUnusedResultAWarning about CallExpr to decls that are pure/const/warnunusedresult, fixing a fixme. 5) change warn_attribute_wrong_decl_type to not pass in english strings, instead, pass in integers and use %select. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64543 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-11Initial implementation of function overloading in C.Douglas Gregor
This commit adds a new attribute, "overloadable", that enables C++ function overloading in C. The attribute can only be added to function declarations, e.g., int *f(int) __attribute__((overloadable)); If the "overloadable" attribute exists on a function with a given name, *all* functions with that name (and in that scope) must have the "overloadable" attribute. Sets of overloaded functions with the "overloadable" attribute then follow the normal C++ rules for overloaded functions, e.g., overloads must have different parameter-type-lists from each other. When calling an overloaded function in C, we follow the same overloading rules as C++, with three extensions to the set of standard conversions: - A value of a given struct or union type T can be converted to the type T. This is just the identity conversion. (In C++, this would go through a copy constructor). - A value of pointer type T* can be converted to a value of type U* if T and U are compatible types. This conversion has Conversion rank (it's considered a pointer conversion in C). - A value of type T can be converted to a value of type U if T and U are compatible (and are not both pointer types). This conversion has Conversion rank (it's considered to be a new kind of conversion unique to C, a "compatible" conversion). Known defects (and, therefore, next steps): 1) The standard-conversion handling does not understand conversions involving _Complex or vector extensions, so it is likely to get these wrong. We need to add these conversions. 2) All overloadable functions with the same name will have the same linkage name, which means we'll get a collision in the linker (if not sooner). We'll need to mangle the names of these functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64336 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-27Implementation of gcc mode attribute; this is significant because Eli Friedman
it fixes PR2204. Not too much to say about the implementation; it works in a similar way to the vector size attribute. At some point, we need to modify the targets to provide information about the appropriate types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51577 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
