On the devvp branch, I had to edit all device sources in the kernel.
To verify that everything at least compiled before trying to test
various architectures, I set up crosscompilers on my i386-current
I tried to set them up by running gnu/dist/toolchain/configure with
the appropriate target. Here are some results:
* m68k--netbsdelf: seems to work fine, except for 3 problems:
* sys/dev/scsipi/ch.c will make gcc SEGV when compiling
with -O2 or -Os.
* gas doesn't like sys/arch/m68k/fpsp/*. It spews errors
for out of range branches, but the branches look
just fine in the (preprocessed) assembly code.
* atari locore.s gives:
Error: parse error -- statement `move l a0@(0x42ec),%d0' ignored
I assume that's just a slight change of syntax.
* alpha--netbsd: gcc gets internal errors for basically every other
file, with or without optimization. gas seems to work ok. I didn't
get to the link stages obviously..
* arm--netbsdelf, powerpc--netbsd, mipsel--netbsd (both be and le)
seem to work fine. vax--netbsdelf also seems okay, but it also
has problems with sys/dev/scsipi/ch.c, like m68k (note that
I did not run any of these kernels yet, so I can't be sure if
there were possible bugs in the generated code)
* I wasn't able to configure an sh crosscompiler, basically
every target I tried eventually led to:
configure: error: GAS does not know what format to use for target sh-unknown-net
