It is transparent for the user's processes, so why do you expect any changes in gcc?
Well, if Woodcrest is a new type of processor (even though it's based on Xeon), it might have new registers, ... that have to be implemented in gcc. If it's not implemented in gcc, you might not get all the performance you might be looking for/expecting. Just as you can, for example, specify: gcc -mtune=pentium4 gcc -mtune=prescott gcc -mtune=nocona http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/i386-and-x86_002d64-Options.html... pentium4, pentium4m Intel Pentium4 CPU with MMX, SSE and SSE2 instruction set support. prescott Improved version of Intel Pentium4 CPU with MMX, SSE, SSE2 and SSE3 instruction set support. nocona Improved version of Intel Pentium4 CPU with 64-bit extensions, MMX, SSE, SSE2 and SSE3 instruction set support. Maybe there's a: gcc -mtune=woodcrest The question would be: is there a -mtune=woodcrest? TIA Rafa
