I was wondering how I can enable 64 bit support and v9 instruction
scheduling for an Ultra 1 Model 170 running Solaris2.5. This is
apparently not possible when the target is
"sparc-sun-solaris2.5.1".
I thought I'd try specifying "sparc64-sun-elf". But I don't know
if this makes any sense. Does anyone have any suggestions?
Solaris still lacks any 64-bit userland support on UltraSparc systems.
However you can get Ultra optimized instruction scheduling by passing
"-mcpu=ultrasparc" to egcs.
