Add -Wpartial-availability.
This warns when using decls that are not available on all deployment targets.
For example, a call to
- (void)ppartialMethod __attribute__((availability(macosx,introduced=10.8)));
will warn if -mmacosx-version-min is set to less than 10.8.
To silence the warning, one has to explicitly redeclare the method like so:
@interface Whatever(MountainLionAPI)
- (void)ppartialMethod;
@end
This way, one cannot accidentally call a function that isn't available
everywhere. Having to add the redeclaration will hopefully remind the user
to add an explicit respondsToSelector: call as well.
Some projects build against old SDKs to get this effect, but building against
old SDKs suppresses some bug fixes -- see http://crbug.com/463171 for examples.
The hope is that SDK headers are annotated well enough with availability
attributes that new SDK + this warning offers the same amount of protection
as using an old SDK.

[InstCombine] Don't fold a GEP into itself through a PHI node
This can only occur (I think) through the back-edge of the loop.
However, folding a GEP into itself means that the value of the previous
iteration needs to be stored in the meantime, thus requiring an
additional register variable to be live, but not actually achieving
anything (the gep still needs to be executed once per loop iteration).
The attached test case is derived from:
typedef unsigned uint32;
typedef unsigned char uint8;
inline uint8 *f(uint32 value, uint8 *target) {
while (value >= 0x80) {
value >>= 7;
++target;
}
++target;
return target;
}
uint8 *g(uint32 b, uint8 *target) {
target = f(b, f(42, target));
return target;
}
What happens is that the GEP stored in incptr2 is folded into itself
through the loop's back-edge and the phi-node stored in loopptr,
effectively incrementing the ptr by "2" in each iteration instead of "1".
In this case, it is actually increasing the number of GEPs required as
the GEP before the loop can't be folded away anymore. For comparison:
With this patch:

Split the object streamer callback in one per file format.
There are two main advantages to doing this
* Targets that only need to handle one of the formats specially don't have
to worry about the others. For example, x86 now only registers a
constructor for the COFF streamer.
* Changes to the arguments passed to one format constructor will not impact
the other formats.

Some subregisters are only to indicate different access sizes, while not

Currently v2i64 vectors shifts (non-equal shift amounts) are scalarized, costing 4 x extract, 2 x x86-shifts and 2 x insert instructions - and it gets even more awkward on 32-bit targets.
This patch separately shifts the vector by both shift amounts and then shuffles the partial results back together, costing 2 x shuffles and 2 x sse-shifts instructions (+ 2 movs on pre-AVX hardware).
Note - this patch only improves the SHL / LSHR logical shifts as only these are supported in SSE hardware.
