and use the `--with-gnu-as' configure option when configuring gcc.
GNU as is distributed as part of the binutils package.
Under Irix 6, if you are using Irix `cc' as your bootstrap
compiler, you must ensure that the N32 ABI is in use. To test
this, compile a simple C file with `cc' and then run `file'
on the resulting object file. The output should look like:
test.o: ELF N32 MSB ...
If you see:
test.o: ELF 32-bit MSB
then your version of `cc' uses the O32 ABI default. You should
set the environment variable `CC' to `cc -n32' before configuring
GCC.

# We force the use of the O32 ABI for two reasons.
# 1) For consistency, because some versions of Irix 6 default to the O32 ABI
# and some versions default to the N64 ABI.
# 2) To avoid SGI compiler bugs. The v6.x and v7.0 compilers from SGI have
# bugs that cause gcc to be miscompiled when the N32 or N64 ABIs are used.
# The O32 ABI is known to be OK.
