Matt Arsenault	138d429065	AMDGPU: Always allocate emergency stack slot at offset 0 This allows us to ensure that 0 is never a valid pointer to a user object, and ensures that the offset is always legal without needing a register to access it. This comes at the cost of usable offsets and wasted stack space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@295877 91177308-0d34-0410-b5e6-96231b3b80d8	2017-02-22 21:05:25 +00:00

AMDGPU: Always allocate emergency stack slot at offset 0

This allows us to ensure that 0 is never a valid pointer
to a user object, and ensures that the offset is always legal
without needing a register to access it. This comes at the cost
of usable offsets and wasted stack space.

AMDGPU: Fix kernel argument alignment impacting stack size

Don't use AllocateStack because kernel arguments have nothing
to do with the stack. The ensureMaxAlignment call was still
changing the stack alignment.
