- Bcc:
hi all,
while building a gcc cross compiler i am trying to restrict the number of
registers available to the compiler. to achieve this i modifed the machine
header file to reduce the number of GPRs and FPRs and re-allocate them for
various purposes such as SP, FP etc. but this generates an 'internal
compiler error: program cc1 got fatal signal 11" error message during
complitation. what other changes do i need to make? i have to do this since
-ffixed-reg option does not guarantee aviodance of those registers by gcc.
another related question is about the macro reg_class_contents. i was
unable to follow its description to undertand the operation. why more than 1
entry per register-class?
sorry if there querries are oft-repeated.
thanks,
piyush
