2010-07-06Validated by nightly-test runs on x86 and x86-64 darwin, including afterJohn McCall
self-host. Hopefully these results hold up on different platforms. I tried to keep the GNU ObjC runtime happy, but it's hard for me to test. Reimplement how clang generates IR for exceptions. Instead of creating new invoke destinations which sequentially chain to the previous destination, push a more semantic representation of *why* we need the cleanup/catch/filter behavior, then collect that information into a single landing pad upon request. Also reorganizes how normal cleanups (i.e. cleanups triggered by non-exceptional control flow) are generated, since it's actually fairly closely tied in with the former. Remove the need to track which cleanup scope a block is associated with. Document a lot of previously poorly-understood (by me, at least) behavior. The new framework implements the Horrible Hack (tm), which requires every landing pad to have a catch-all so that inlining will work. Clang no longer requires the Horrible Hack just to make exceptions flow correctly within a function, however. The HH is an unfortunate requirement of LLVM's EH IR. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107631 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-03Mangle Objective-C pointers and block pointers in the Microsoft C++ Mangler.Charles Davis
ObjC pointers were easy enough (as far as the ABI is concerned, they're just pointers to structs), but I had to invent a new mangling for block pointers. This is particularly worrying with the Microsoft ABI, because it is a vendor-specific ABI; extending it could come back to bite us later when MS extends it on their own (and you know they will). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107572 91177308-0d34-0410-b5e6-96231b3b80d8

Only actual functions get mangled correctly; I don't know how to fix it for function pointers yet. Thanks to John McCall for the hint. Also, mangle anonymous tag types.
