[PATCH 4/4] [AARCH64,NEON] Fix unnecessary moves in vst[234]q_* intrinsics

Charles Baylis charles.baylis@linaro.org
Thu Sep 18 19:41:00 GMT 2014


This patch improves code generation of vst[234]q_* intrinsics by avoiding use
of the __builtin_aarch64_set_qreg_* builtins to generate a temporary
__builtin_aarch64_simd_XX variable. Instead, a union is used for type-punning,
which avoids generation of some unnecessary move instructions. This idiom is
already used in several other intrinsics.

This patch is independent of the previous patches in the series.

Tested (with the rest of the patch series) with make check on aarch64-oe-linux
with qemu, and also causes no regressions in clyon's NEON intrinsics tests.

	intrinsic types and __builtin_aarch64_simd* types.
