Dual Ross RT625 processors @ 100MHz
>Description:
When I try making bootstrap, the stage 2 compilation
hangs when compiling c-typeck.c.  I aborted the process
after 12 hours CPU time.  When compiling the file with the
same flags but -mv8 or -msupersparc, the compilation
completes in 1.5 minutes.

I configured gcc with the following options:

  --with-cpu=hypersparc --disable-multilib
  --enable-shared=libstdc++,libffi,zlib,boehm-gc,libjava

>How-To-Repeat:
Bootstrap 3.3 on SPARC with "--with-cpu=hypersparc"
>Fix:
Workaround: Use "--with-cpu=v8" instead.
