Maybe spelling it -mtext-model=kseg0 would be more descriptive. >> that tells gcc to do the right thing in the first place? > > Gcc still generates MIPS assembler macros, so such a switch would > do nothing yet.

Gcc can at least pass the setting along to the assembler (which would have to grow such an option as well, either as a command line switch or (preferred) a .directive). zw
