; On Southern Islands GPUs the local address space(3) uses 32-bit pointers and
; the global address space(1) uses 64-bit pointers.  These tests check to make sure
; the correct pointer size is used for the local address space.

; The e{{32|64}} suffix on the instructions refers to the encoding size and not
; the size of the operands.  The operand size is denoted in the instruction name.
; Instructions with B32, U32, and I32 in their name take 32-bit operands, while
; instructions with B64, U64, and I64 take 64-bit operands.
