To eliminate those annoying manual interventions in making kernels
using pgcc, here is a trivial script. I just say 'make CC=ccc'
It assumes that the distribution cc is renamed to kcc, pgcc is
installed as gcc
#
#!/bin/sh
#
# /usr/local/bin/ccc
#
# script to permit optimal compilation of the kernel using pgcc
# with work-arounds for bugs and other inconveniences
#
for i in $*
do
case $i in
../../kern/kern_xxx.c) # pgcc bug -- use this as an
# opportunity to hook in the
# missing run-time without
# touching the makefile
if gcc $* ../../libkern/muldi3.c ; then
echo gcc -O compile done
ld -r -o kern_xxx2.o kern_xxx.o muldi3.o || exit 1
mv -f kern_xxx2.o kern_xxx.o
exit 0;
else
echo kern_xxx gcc -O failed
exit 1
fi

*)

esac
done
if ! gcc -O6 -fomit-frame-pointer $* ; then # pgcc bug
rm -f cc1.core
if ! gcc -O3 -fomit-frame-pointer$* ; then # assembly syntax problem
rm -f cc1.core
if ! kcc -O $* ; then # *your* problem
echo All compilers failed.
exit 1
else
echo kcc -O compile done.
fi
else
echo gcc -O3 compile done.
fi
else
echo gcc -O6 compile done.
fi
exit 0
