Subject: x86: Intel Core processors do not support CMPXCHG16B
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3eda60e3d6edfddf081ed2e8eb0901b6f6279413;p=binutils-gdb.git

x86: Intel Core processors do not support CMPXCHG16B

This being a 64-bit-only instruction (see also i386-opc.tbl) it cannot
possibly be supported by CPUs not supporting 64-bit mode.
