I would like to report a partial success with using gcc-2.3.1 for kernel
compiling.
I had to do the following in order to be able to link/boot this new kernel:
compile init_main.c with gcc-1.39, otherwise the link stage would fail with
symbol error for "___main".
compile machdep.c with gcc-1.39, otherwise the kernel will enter a endless
reboot loop.
(This has to do with some differences in packing between 1.39 & 2.3.1 )
compile pccons_{vga,out,kbd} with gcc-1.39, else multiply defined symbols.
(This is really weird.)
My machine have been running this kernel since saturday night, with "only"
2 crashes/hangs.
The hanging is seen when running a gcc-1.39 kernel, probably has something to
do with swapping.
The crash happens when running the byte-benchmarks (4 concurrents shells),
and gives a "vm_fault(blah....) trap code 12".
It also happens when using a gcc-1.39 compiled kernel.
I haven't tried comparing the performance using the different kernels.
.
