gcc 4.1.0 ppc64 fix
Hi,
Latest kexec tools for PPC64 with purgatory patch
(ppc64-kdump-purgatory-backup-support.patch) was not working with gcc
version 4.1.0 due to the change in object file generation.
Here is the patch to fix this issue.
This patch is created on top of the following level of
kexec-tools:
- kexec-tools-1.101.tar.gz (from eric biederman's site or
from lse site)
- kexec-tools-1.101-kdump6.patch (consolidated patch posted
on
http://lse.sourceforge.net/kdump/patches/1.101-kdump6/kexec-tools-1.101-kdump6.patch)
Review and suggestions are welcome.
Note:
Resending the patch since its not delivered to both fastboot and
linuxppc64-dev mailing list.
Regards,
Mohan.
GCC 4.1.0 (for ppc) generates object files without
dot-symbols. This new format breaks subroutine calls using
assembly language mnemonic. This patch restores the old
convention, i.e produce the object files with dot-symbols
using the flag "-mcall-aixdesc".
Note:
Earlier versions of gcc compilers generated object files
with dot-symbols.
