2009-09-25Fix <rdar://problem/7249327> by allowing silent conversions between signed ↵Ted Kremenek

complete (or, possibly causing template instantiation). Test this via some explicit specializations of member functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82732 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-24WIP implementation of explicit function template specialization. ThisDouglas Gregor
first implementation recognizes when a function declaration is an explicit function template specialization (based on the presence of a template<> header), performs template argument deduction + ambiguity resolution to determine which template is being specialized, and hooks There are many caveats here: - We completely and totally drop any explicitly-specified template arguments on the floor - We don't diagnose any of the extra semantic things that we should diagnose. - I haven't looked to see that we're getting the right linkage for explicit specializations On a happy note, this silences a bunch of errors that show up in libstdc++'s <iostream>, although Clang still can't get through the entire header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82728 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-24Refactor the representation of qualifiers to bring ExtQualType out of theJohn McCall
Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our use of qualifiers and fix a few places that weren't dealing with qualifiers quite right; many more remain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82705 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-24When building CFGs, no longer reverse the statements in the CFGBlock. InsteadTed Kremenek
have the iterators and operator[] handle the traversal of statements, as they are stored in reverse order. Tests show this has no real performance impact, but it does simply the CFG construction logic and will make it slightly easier to change the allocation strategy for CFGBlocks (as we have fewer copies). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82702 91177308-0d34-0410-b5e6-96231b3b80d8
