Hello,
I continue building on NetBSD: I'm using 1.6.1 btw.I just upgraded to it during my short absence.
ANyway reissuing make (specifically gmake, I installed gnu-make) every time continues compilation.
But it now fails with an undefined reference:
gmake[2]: Entering directory `/home/multix/kaffe-cvs/kaffe/kaffe/

is d0 an internal symbol of kaffe or is it part of some system library ?
After grepping & googling around to find a good way to deal with that ugly 'd0', I concluded that it was coming from FLUSH_DCACHE, and promptly found a post from Kiyo confirming that ;)
Then I googled around for NetBSD and m68k docs on flushing the cache on m68k, and after a while I found m68k_sync_icache[1]. Googling for that gave me another post from Kiyo mentioning it as a possible solution in this context. ;)
So I've created a patch, analogous to the mips FLUSH_DCACHE, that uses th m68k_sync_icache function, and updated the config.frag on m68k/netbsd to link in libm68k.
I've checked the patch in, so it would be nice if Riccardo could try it out on his m68k-netbsd box. If it works, I'd remove the commented out assembler code.
cheers, dalibor topic
