NetBSD/macppc kernel status

Recent options/configs used:

makoptions CC="cc -fno-strict-aliasing"

The existing NetBSD source tree may not be complient with 'strict aliasing' defined in ANSI-C starndard. It's been just fortunate this strict-aliasing option was not enabled even with -O2 until gcc-2.95.3 is used as toolchain. Starting gcc-3.x this option is enabled with -O2 and this becomes harmful for NetBSD source tree using union construct. To avoid this issue, set -fno-strict-aliasing till we put all strict-aliasing complient src.

makoptions CC="gcc3 -fno-strict-aliasing"

Enable to use gcc3 for kernel compile

To get ts version compiled, you need

egcs-1.1.2

Prior to -current date 20011030 or arroud that date, cc ( and gcc ) is egcs-1.1.2 and binutils are version 2.9.x, which you may have following problems. If you don't need 'Options ALTIVEC', just remove the line from kernel configuration.

cc -O2 -pipe -Werror -Wall -Wpointer-arith -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized -Wno-main -msoft-float -ffreestanding -I. -I../../../../arch -I../../../.. -nostdinc - DDIAGNOSTIC -DMAXUSERS=32 -D_KERNEL -D_KERNEL_OPT -Dmacppc -c ../../../../arch/powerpc/powerpc/altivec.c
