2011-03-11Use a slightly more semantic interface for emitting call arguments.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127494 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Use the "undergoes default argument promotion" bit on parameters toJohn McCall
simplify the logic of initializing function parameters so that we don't need both a variable declaration and a type in FunctionArgList. This also means that we need to propagate the CGFunctionInfo down in a lot of places rather than recalculating it from the FAL. There's more we can do to eliminate redundancy here, and I've left FIXMEs behind to do it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127314 91177308-0d34-0410-b5e6-96231b3b80d8

ambiguous context. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116567 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-17Currently we're initializing the vtable pointers of a class only afterJohn McCall
the bases are completely initialized. This won't work --- base initializer expressions can rely on the vtables having been set up. Check for uses of 'this' in the initializers and force a vtable initialization if found. This might not be good enough; we might need to extend this to handle the possibility of arbitrary code finding an external reference to this (not yet completely-constructed!) object and accessing through it, in which case we'll probably find ourselves doing a lot more unnecessary stores. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114153 91177308-0d34-0410-b5e6-96231b3b80d8
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

2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8

initializer of (). Make sure to use a simple memset() when we can, or fall back to generating a loop when a simple memset will not suffice. Fixes <rdar://problem/8212208>, a regression due to my work in r107857. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108977 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Teach IR generation how to lazily emit cleanups. This has a lot of advantages,John McCall
mostly in avoiding unnecessary work at compile time but also in producing more sensible block orderings. Move the destructor cleanups for local variables over to use lazy cleanups. Eventually all cleanups will do this; for now we have some awkward code duplication. Tell IR generation just to never produce landing pads in -fno-exceptions. This is a much more comprehensive solution to a problem which previously was half-solved by checks in most cleanup-generation spots. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108270 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
