I've completed testing on ia64-linux.
I've bootstrapped the compiler with and without the patch. I used
BOOT_CFLAGS='-O2 -g --save-temps' and then compared the .s files
from stage2 (which gets -gtoggle and thus -g0, thus ignoring the
debug differences caused by different build paths). There were no
differences at all, except those expected by the patched ia64.c.
Thus I conclude that the unwind directives are identical with and
without the patch.
Is the patch ok?
