2009-12-27Promote arguments of frameaddr / returnaddr builtins to i32 type, when needed.Anton Korobeynikov
This is needed for the platforms, where bitwidth of "int" is not 32 bits (e.g. 16 on msp430). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92176 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-26Don't look through casts when looking for the underlying decl for a functionEli Friedman
call; the standard doesn't expect us to, and the program could be doing something crazy. Fixes PR5882. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92166 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-24Egregious, disgusting workaround for PR5866. We need to rework how weDouglas Gregor
keep track of friends within templates, which will provide a real for PR5866. For now, this makes sure we don't do something entirely stupid with friends of specializations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92143 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-24When transforming CXXExprWithTemporaries and CXXBindTemporaryExprDouglas Gregor
expressions (e.g., for template instantiation), just transform the subexpressions and return those, since the temporary-related nodes will be implicitly regenerated. Fixes PR5867, but I said that before... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92135 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-24InitializationSequence handles binding to temporaries, so thatDouglas Gregor
argument-passing doesn't have to. Fixes PR5867, where we were binding a temporary twice in the AST and, therefore, calling its destructor twice. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92131 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-24Fix the clang-on-clang build: APFloat reports underflow whenever we get aJohn McCall
denormal, but we only want to diagnose if we underflowed to zero. This allows people to write constants in the denormal range. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92129 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-24Tweak the text of several main() diagnostics and punch a hole specifically forJohn McCall
Darwin's sekrit fourth argument. This should probably be factored to let targets make target-specific decisions about what main() should look like.

2009-12-24Fix for bug 5691.David Chisnall
This fixes throwing exceptions inside @catch blocks nested inside outer @try blocks and also fixes jumping from an inner @finally to an outer @finally (via any relevant @catch blocks). The code exhibiting this bug was based on code from CGObjCMac. I believe that this bug may still be present on the Mac runtimes, although the test case in the bug contains a few GNUisms and won't compile without some minor tweaks with Apple's libobjc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92117 91177308-0d34-0410-b5e6-96231b3b80d8
