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.

GlobalDCE: Improve performance for large modules containing comdats.
...
When we encounter a global with a comdat, rather than iterating over
every global in the module to find globals in the same comdat, store the
members in a multimap. This effectively lowers the complexity to O(N log N),
improving performance significantly for large modules such as might be
encountered during LTO.
It looks like we used to do something like this until r219191.
No functional change.

Fixing dependencies for native tablegen.

The dependencies for cross-built tablegen were a bit confused. This fixes that. The following dependencies are now enforced:
(1) Tablegen tasks depend on the native tablegen
(2) Native tablegen depends on the cross-compiled tablegen
Although the native tablegen doesn't actually require the cross tablegen, having this dependency forces the native tablegen to rebuild whenever the cross tablegen changes.

[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:
define i8* @test4(i32 %value, i8* %buffer) {
entry:
%cmp = icmp ugt i32 %value, 127
br i1 %cmp, label %loop.header, label %exit

%buffer.pn = phi i8* [ %buffer, %loop.header ], [ %loopptr, %loop.body ]
