Optimizing codegen for absolute differences in AArch64

2025-01-14 Thread Jennifer Schmitz via Gcc
We are working on improving codegen for the following test cases (for all integer types T): T foo (T x, T y) { T diff = x - y; return x > y ? diff : -diff; } T bar (T x, T y) { T diff1 = x - y; T diff2 = y - x; return x > y ? diff1 : diff2; } For signed integers, we already proposed a
