From a0f7013add6b1737e9a5e5d63cdf41ab2ebca0bf Mon Sep 17 00:00:00 2001 From: Matthew Wahab Date: Fri, 11 Dec 2015 09:56:07 +0000 Subject: [PATCH] [AArch64][Patch 3/5] Adjust maximum number of instruction aliases. The Statistical Profile Extension adds the instruction PSB CSYNC as an alias for the HINT #17 instruction. The HINT instruction currently has 8 aliases, which is the maximum number allowed. This patch raises to 16 the limit on the number of aliases an instruction can have. opcodes/ 2015-12-11 Matthew Wahab * aarch64-gen.c (find_alias_opcode): Set max_num_aliases to 16.
