I am having difficulty compiling for my P4 machine.
I get the following assembler error messages when i compile with
-march=pentium4.

> .s:2905: Error: no such 386 instruction: `movsd 88(%esp),%xmm1'
etc. ...
I shouldn't have to build gcc as a cross-compiler do I?
(My compile machine is a dual cpu P3 with lots of RAM, but i need
to ship product to P3s P4s and Athlon's.)
