This test could use some refactoring.
Individual macro checks could be collapsed to
// RUN: ... --check-prefixes=...,FMA
// FMA-DAG: #define FP_FAST_FMA 1

Use  so we don't have to keep updating the number?
gfx1032 does not support XNACK. It should have the same target features as gfx1032.
Delete as the line above is using this reserved number.
