Subject: [AArch64][SVE 06/32] Generalise parse_neon_reg_list
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=10d76650106ac50cd690536014244a0a03778a8e;p=binutils-gdb.git

[AArch64][SVE 06/32] Generalise parse_neon_reg_list

Rename parse_neon_reg_list to parse_vector_reg_list and take
in the required register type as an argument.  Later patches
will reuse the function for SVE registers.

gas/
	* config/tc-aarch64.c (parse_neon_reg_list): Rename to...
	(parse_vector_reg_list): ...this and take a register type
	as input.
	(parse_operands): Update accordingly.
