Subject: [PATCH] S/390: UTF conversion modules - use .insn to avoid 'as' errors
Hi,
the attached patch fixes the problem mentioned by Aurelien in:
http://sources.redhat.com/ml/libc-alpha/2011-03/msg00000.html
The UTF conversion modules detect at runtime whether the conversion
instructions can be used or not. So 'as' should not reject them when
building for a lower CPU level. On the other hand it should
nevertheless be possible to build the modules optimizing for a higher
CPU level without as rejecting new instructions. One way is to
introduce -march=all in 'as' in order to basically disable the
instruction checks. I've committed a patch to binutils introducing
-march=all so that it can be used in the future:
http://sourceware.org/ml/binutils/2011-03/msg00355.html
But we cannot use that option right now since it would bind glibc
build to upstream binutils. For now I don't see a way around
replacing the mnemonics with .insn .
Done with the attached patch. I've verified that the same binary code
is generated for the modules.
Bye,
-Andreas-
