2016-09-07Improve aarch64_legitimize_address - avoid splitting the offset if it is ↵Wilco Dijkstra2-2/+17
supported. Improve aarch64_legitimize_address - avoid splitting the offset if it is supported. When we do split, take the mode size into account. BLKmode falls into the unaligned case but should be treated like LDP/STP. This improves codesize slightly due to fewer base address calculations: int f(int *p) { return p[5000] + p[7000]; } Now generates: f: add x0, x0, 16384 ldr w1, [x0, 3616] ldr w0, [x0, 11616] add w0, w1, w0 ret instead of: f: add x1, x0, 16384 add x0, x0, 24576 ldr w1, [x1, 3616] ldr w0, [x0, 3424] add w0, w1, w0 ret gcc/ * config/aarch64/aarch64.c (aarch64_legitimize_address): Avoid use of base_offset if offset already in range.
