[PATCH 2/4] [AARCH64,NEON] Convert arm_neon.h to use new builtins for vld[234](q?)_lane_*

Charles Baylis charles.baylis@linaro.org
Thu Sep 18 19:40:00 GMT 2014


This patch replaces the inline assembler implementations of the
vld[234](q?)_lane_* intrinsics with new versions which exploit the new builtin
functions added in patch 1.

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.

<DATE>  Charles Baylis  <charles.baylis@linaro.org>

	* config/aarch64/arm_neon.h (__LD2_LANE_FUNC): Rewrite using builtins,
	update uses to use new macro arguments.
	(__LD3_LANE_FUNC): Likewise.
	(__LD4_LANE_FUNC): Likewise.
