Subject: * x86id.c: Add support for 64-bit far jmp/call.  These are not listed in the
X-Git-Tag: v0.5.0~8^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=807084d3ffc507a2b0f932e1ee83c8f94bd8a07a;p=yasm

* x86id.c: Add support for 64-bit far jmp/call.  These are not listed in the
AMD64 ISA reference but are in the Intel EM64T reference.
* x86arch.h: Add CPU_EM64T flag.
* x86parse.gap: Add CPU_EM64T as feature and enable it as part of "prescott".
* far64.asm: Test for 64-bit far jmp/call.
