2010-09-15one piece of code is responsible for the lifetime of every aggregateJohn McCall
slot. The easiest way to do that was to bundle up the information we care about for aggregate slots into a new structure which demands that its creators at least consider the question. I could probably be convinced that the ObjC 'needs GC' bit should be rolled into this structure. Implement generalized copy elision. The main obstacle here is that IR-generation must be much more careful about making sure that exactly git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113962 91177308-0d34-0410-b5e6-96231b3b80d8

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

variables within blocks. We loosely follow GCC's mangling, but since these are always internal symbols the names don't really matter.

2010-02-23Unconditionally support block introspection data in a new field at the endBlaine Garst
of the block descriptor field. This field is the ObjC style @encode signature of the implementation function, and was to this point conditionally provided in the block literal data structure. That provisional support is removed. Additionally, eliminate unused enumerations for the block literal flags field. The first shipping ABI unconditionally set (1<<29) but this bit is unused by the runtime, so the second ABI will unconditionally have (1<<30) set so that the runtime can in fact distinguish whether the additional data is present or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96989 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-05Standardize the parsing of function type attributes in a way thatJohn McCall
follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95436 91177308-0d34-0410-b5e6-96231b3b80d8
