Description Steven Hillis 2007-02-25 02:00:12 UTC 
Setting -mcpu=ultrasparc or -mcpu=v9 in /etc/make.conf causes "unknown
architecture" errors on world or kernel builds.

Setting the flags overwrites the CPU_SPEC that's normally set to __sparc64__.

Fix: Apply the attached patch which adds the following to
/usr/src/contrib/gcc/config/sparc/freebsd.h:

builtin_define ("__sparc64__");
builtin_define ("__sparc_v9__");
builtin_define ("__sparcv9");
builtin_define ("__arch64__");


Patch attached with submission follows:
How-To-Repeat: Add -mcpu=ultrasparc to you CFLAGS= configuration in /etc/make.conf, then
try to compile world or any kernel.

  Allow the targeted CPU type to be set via -mcpu instead of
  limiting to the hardcoded equivalent of -mcpu=ultrasparc.
