These days we always initialise them at start-up, temporarily forcing a conducive set of flags if necessary. This patch removes some vestiges of the old way of doing things. Tested on aarch64-linux-gnu & pushed. Richard gcc/ * config/aarch64/aarch64-protos.h (aarch64_init_simd_builtins): Remove prototype. * config/aarch64/aarch64-builtins.cc (aarch64_simd_builtins_initialized_p): Delete.
