Bug#341514: libc6-sparc64: All 64-bit binaries fail to execute.
Unless someone is going to make a concerted and dedicated development effort to do the necessary full analysis and backport all of the necessary changes, I would suggest to simply not enable TLS for the sparc64 glibc build at this time so at least we have something which works. That works. Remove sparc64-tls.dpatch entirely and configure sparc64 with --without-tls. Working debian/sysdeps/sparc.mk attached.

Bug#341514: libc6-sparc64: All 64-bit binaries fail to execute.
There are some critical things missing in the sparc64 TLS support code
in the current debian glibc tree, for example none of the TLS
relcation support is in sysdeps/sparc/sparc64/dl-machine.h, and
therefore so no binary linked against 64-bit libc can execute.
Not even /lib64/libc.so.6 --version will work, it will fail
because the dynamic linker doesn't understand the TLS relocations
present in the /libc64/libc.so.64 binary.
Replacing Aurelien's patch with this one fixes the
/lib64/libc.so.6: error while loading shared libraries: unexpected reloc type
0x4f
problem, and /lib64/libc.so.6 --version works fine.
However, 64-bit binaries segfault.

If this sparc TLS support has been backported, this back has missed significant chunks of the necessary changes and now all 64-bit binaries fail to execute on the system. This is a known problem. It was _not_ backported; rather, binutils was updated to one which supported sparc64 TLS, and glibc's configury automatically started enabling it. An upload to fix this has been waiting on a pile of failures to build, also because of the new binutils. Sorry. I would suggest trying to execute a Hello World program, post-build, to avoid major errors like this. There is no way that any of the testsuite executed properly. Perhaps it was built successfully, but none of the programs linking against libc could have executed properly due to this bug. We run the testsuite. Sparc64 is a special case, however, because we can't assume that the buildd can run sparc64 binaries - in practice it can, of course, I'm sure we could do better than we do. -- Daniel Jacobowitz CodeSourcery, LLC -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

However, 64-bit binaries segfault. I would suggest not randomly cherry picking patches from the CVS mainline hoping it will make things start to work. There were several other changes necessary to support TLS properly on sparc64 which went into the glibc CVS tree. You'll need more than just the relocation support. Unless someone is going to make a concerted and dedicated development effort to do the necessary full analysis and backport all of the necessary changes, I would suggest to simply not enable TLS for the sparc64 glibc build at this time so at least we have something which works. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
