Fix bug in BugReporter where we didn't handle emitting diagnostics for
...
empty CFGBlocks that only contained a terminator.
Added improved diagnostics for break and continue statements and default branches in switch statements.
This fixes <rdar://problem/5889244>.

Remove the code from CodeGenPrepare that moved getresult instructions
...
to the block that defines their operands. This doesn't work in the
case that the operand is an invoke, because invoke is a terminator
and must be the last instruction in a block.
Replace it with support in SelectionDAGISel for copying struct values
into sequences of virtual registers.

remove the 'unused static' diagnostic from codegen. This should be

reimplemented in Sema someday. This is tracked in PR2236. Until then
disabling it removes some bogus diagnostics (see 2236).

MMX argument passing fixes:
...
On Darwin / Linux x86-32, v8i8, v4i16, v2i32 values are passed in MM[0-2].
On Darwin / Linux x86-32, v1i64 values are passed in memory.
On Darwin x86-64, v8i8, v4i16, v2i32 values are passed in XMM[0-7].
On Darwin x86-64, v1i64 values are passed in 64-bit GPRs.

Loosen up an assertion to allow intrinsics. I really have no
...
idea what this code (findNonImmUse) does, so I'm only guessing
that this is the right thing. It would be really really nice
if this had comments and perhaps switched to SmallPtrSet
(hint hint) :)

goes back to the block, e.g.:
Threading edge through bool from 'bb37.us.thread3829' to 'bb37.us' with cost: 1, across block:

%D1361.1.us = phi i32 [ %tmp36, %bb33 ], [ %D1361.1.us, %bb37.us ], [ 0, %bb37.us.thread3829 ] ; <i32> [#uses=2]

Do a better job at computing dead symbols.
...
Implemented support for better localized leaks in the CF reference count checker.
Now leaks should be flagged close to where they occur.
This should implement the desired functionality in <rdar://problem/5879592>, although the diagnostics still need to be improved.

Fix bug in x86 memcpy / memset lowering. If there are trailing bytes not handled by rep instructions, a new memcpy / memset is introduced for them. However, since source / destination addresses are already adjusted, their offsets should be zero.
