[parisc-linux] 64-bit "Internal compiler error" emit-rtl.c:1560

[Grant Grundler]

Hi toolchain experts,

I'm working on kernel CONFIG_SMP support and can't compile a 64-bit kernel.
32-bit toolchain builds and links a (buggy) kernel.
Using the xc-20010117.tar.gz provided by Matt in both cases.

Any clues what's wrong?

thanks,
grant

Enabled CONFIG_SMP with the following sequence:
    cvs update -A
    vi Makefile		# set ARCH=parisc64 and CROSS_COMPILE=hppa64-linux-
    make oldconfig
    vi .config		# set CONFIG_SMP=y
    make oldconfig
    make -j4 dep

and then:
