On PPC the stack pointer is X1, but ADJCALLSTACK writes R1.

Fixes PR14315: Register regmask dependency problem with misched.

llvm-svn: 168248

This is a partial solution to PR14351. It removes some of the special
significance of the first incoming phi value in the phi aliasing checking logic
in BasicAA. In the context of a loop, the old logic assumes that the first
incoming value is the interesting one (meaning that it is the one that comes
from outside the loop), but this is often not the case.  With this change, we
now test first the incoming value that comes from a block other than the parent
of the phi being tested.

an initial baseline for enqueued blocks, but use a simple DFS stack
for propagating changes quickly up back edges.

This provides a 3.5% reduction in -fsyntax-only time on sqlite3.c.

just whitespace.

Clean up X86 target feature translation code slightly.  No intended functional change.  Patch by Jung-uk Kim.

test cases require fixes to fast-isel before the verifier can be enabled.

Revert r167799. It's not really correct, and it doesn't fix the problem that it was intended to fix.

This was causing different behavior when using -x objective-c++-cpp-output as
compared to -x objc++-cpp-output.  Specifically, the driver was not adding the
-fcxx-exceptions flag in the latter case.

They are just useless and prevent SmallVector from picking an optimized codepath
for memcpyable elements.

This patch replaces the hard coded GPR pair [R0, R1] of
Intrinsic:arm_ldrexd and [R2, R3] of Intrinsic:arm_strexd with
even/odd GPRPair reg class.
Similar to the lowering of atomic_64 operation.

There are better ways of limiting the amount of information if there is a need
for that.
