Backtrace and disassembly

System: Ubuntu 8.04 development version amd64 arch.
CPU: Intel Core2 Duo
Graphics: Intel i945

The file src/mesa/x86-64/xform4.S in Mesa contains at least one Opcode that is AMD-specific (pfmul, pfadd is 3DNow only). Since x86_64 is no longer AMD-specific this causes an invalid opcode exception and the program crashes.
I'll attach a backtrace + disassembly showing where the problem appears.


To reproduce:
Run any opengl-app that uses _mesa_x86_64_transform_points4_3d_no_rot on a x86-64 machine, with 64-bit userland and an Intel CPU.

Mass version move, cvs -> git
