X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dafb9b6489ef1b45a0831e46d85aa9933de4428e;p=gcc.git

[AArch64_BE 2/4] Big-Endian lane numbering fix

2013-01-23  Alex Velenko  <Alex.Velenko@arm.com>

	* config/aarch64/aarch64-simd.md
	(aarch64_be_checked_get_lane<mode>): New define_expand.
	* config/aarch64/aarch64-simd-builtins.def
	(BUILTIN_VALL (GETLANE, be_checked_get_lane, 0):
	New builtin definition.
	* config/aarch64/arm_neon.h: (__aarch64_vget_lane_any):
	Use new safe be builtin.
