4 ; On Southern Islands GPUs the local address space(3) uses 32-bit pointers and
5 ; the global address space(1) uses 64-bit pointers. These tests check to make sure
6 ; the correct pointer size is used for the local address space.
8 ; The e{{32|64}} suffix on the instructions refers to the encoding size and not
9 ; the size of the operands. The operand size is denoted in the instruction name.
10 ; Instructions with B32, U32, and I32 in their name take 32-bit operands, while
11 ; instructions with B64, U64, and I64 take 64-bit operands.
