I totally agree. Instead of claiming gcc is broken dot, find the bugs
and report them. I've been using gcc-2.95.2 to compile linux kernel 2.2.12
2.2.13
on Intel without any problem. There were two serious bugs in gcc-2.95.1 for
PPC. I found
them while working on RTEMS on MCP750 (PowerPC Compaq PCI borad where I also
ported linux).
I reported them and they are now fixed in gcc-2.95.2. One was fixed within a
day even
if it took me a week to localize the bug. The code generated by gcc-2.95.2 on
PPC is much
more compac and efficient than with egcs 1.1.2...
Its free software guys. I you submit good bug reports, be sure the cygnus folks
and
and other GCC gurus will fix them. Alos note that there are *clear* warnings
with the asm
macros on the gcc page...
