ppc-linux and s390-linux compilers requiring 64-bit HWI?

2005-11-26 Thread Jakub Jelinek
Hi! What's the reason why ppc-linux and s390-linux targetted GCC requires 64-bit HWI these days? If it is a native compiler, this means using long long in a huge part of the compiler and therefore slower compile times and bigger memory consumption. ppc-linux configured compiler (nor s390-linux) is
