Subject: The new ia64 assembler is incompatible with glibc
Date: Mon, 14 Feb 2005 06:32:00 -0000 [thread overview]
Message-ID: <20050213171834.GA23705@lucon.org> (raw)

After applied 2 patches enclosed here, I can compile glibc in CVS. But
I got so many failures in "make check":
make[4]: ***

Error 1
It looks like the math functions are wrong. Replacing the new assembler
with the old one fixes the problem.
