Comment(by jdemeyer):
Replying to [comment:6 jhpalmieri]:
> Will that use the Sun assembler?
No, the assembler/linker executables are hardcoded when GCC is compiled.
You can see this by:
{{{
jdemeyer@mark:~$ gcc -print-prog-name=as
/usr/local/binutils-2.20.1/sparc-SunOS-ultrasparc3-gcc-4.4.3/bin/as
}}}
This means that gcc will always use that assembler, which is the GNU
assembler:
{{{
jdemeyer@mark:~$ /usr/local/binutils-2.20.1/sparc-SunOS-
ultrasparc3-gcc-4.4.3/bin/as --version
GNU assembler (GNU Binutils) 2.20.1.20100303

This assembler was configured for a target of `sparc-sun-solaris2.10'.
}}}
I encountered the problem on this ticket while testing #12369. The
default `as` in the PATH is
{{{
jdemeyer@mark:~$ which as
/usr/ccs/bin/as
jdemeyer@mark:~$ as -V
as: Sun Compiler Common 10 Patch 05/06/2005
}}}
So, when compiling GCC, that assembler will be used by default. This can
be overridden using the `AS` environment variable (similarly `LD` for the
linker).
