Subject: [AArch64][SVE 18/32] Tidy definition of aarch64-opc.c:int_reg
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=72e9f31937f063ed6f5991a2b8c00068fa2dc8fc;p=binutils-gdb.git

[AArch64][SVE 18/32] Tidy definition of aarch64-opc.c:int_reg

Use a macro to define 31 regular registers followed by a supplied
value for 0b11111.  The SVE code will also use this for vector base
and offset registers.

opcodes/
	* aarch64-opc.c (BANK): New macro.
	(R32, R64): Take a register number as argument
	(int_reg): Use BANK.
