[Bug target/37344] New: [4.4 Regression] sparc bootstrap fails with Bus error in libgcc2.c

[tbm at cyrius dot com]

Bootstrap of current trunk on SPARC/Linux fails with a Bus error when
compiling libgcc2.c

I'm not sure this is related to PR37279 since genattrtab works fine here.

I configure with:
configure --enable-languages=c,c++ --with-cpu=v8 --with-long-double-128
--build=sparc-linux-gnu --host=sparc-linux-gnu --target=sparc-linux-gnu

Presumably, similar problems on Solaris have been fixed by:

2008-09-11  Jeff Law <law@redhat.com>

        * reload1.c (alter_reg): Undo the BYTE_BIG_ENDIAN correction performed
        by assign_stack_local on the IRA path for stack slot sharing
        as well as the non-IRA path.
