Subject: [AArch64] Increase max_num_aliases in aarch64-gen
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3d731f6949e2b0099cfbe0cf608d60a52a66d354;p=binutils-gdb.git

[AArch64] Increase max_num_aliases in aarch64-gen

Some ARMv8.3 pointer authentication instructions are encoded as HINT aliases,
so to allow more instruction aliases in the generator, max_num_aliases is
increased from 16 to 32.

	* aarch64-gen.c (find_alias_opcode): Increase max_num_aliases to 32.
