Correct negs aliasing on AArch64.
This patch fixes a disassembly issue with the aliases to subs with a shifted register. The subs instruction with the zero register as destination is supposed to alias to cmp and when the first input register is the zero register the subs is supposed to be aliased to negs. This means that a subs with destination and first input registers the zero register is supposed to be a cmp. This is done by raising the priority of the cmp alias. opcodes/ * aarch64-tbl.h (aarch64_opcode_table): Fix alias flag for negs * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. gas/ * testsuite/gas/aarch64/addsub.s: Add negs to zero reg test. * testsuite/gas/aarch64/addsub.d: Likewise.
