At:https://build.opensuse.org/package/show/Virtualization:Staging/qemu building qemu-linux-user for ppc64le,

I get the following build error now: [ 757s] /usr/lib64/gcc/powerpc64le-suse-linux/9/../../../../powerpc64le-suse-linux/ bin/ld: /usr/lib64/gcc/powerpc64le-suse-linux/9/../../../../lib64/libc.a(dl-sysdep. o) and /usr/lib64/gcc/powerpc64le-suse-linux/9/../../../../lib64/libc.a(libc-start. o): warning: multiple common of `__cache_line_size' [ 757s] crc32.c:247:15: error: type of 'crc32_vpmsum' does not match original declaration [-Werror=lto-type-mismatch] [ 757s] contrib/power8-crc/vec_crc32.c:73:14: note: return value type mismatch [ 757s] contrib/power8-crc/vec_crc32.c:73:14: note: type 'unsigned int' should match type 'long unsigned int' [ 757s] contrib/power8-crc/vec_crc32.c:73:14: note: 'crc32_vpmsum' was previously declared here [ 757s] contrib/power8-crc/vec_crc32.c:73:14: note: code may be misoptimized unless '-fno-strict-aliasing' is used [ 757s] lto1: all warnings being treated as errors [ 757s] lto-wrapper: fatal error: c++ returned 1 exit status [ 757s] compilation terminated.

It appears to be related to our settings that warnings are errors, and recent lto enabling activity in zlib. At least, that is my analysis so far. Please investigate.

Yes, the enablement of LTO adds new warnings. I would recommend following what the warning says. It's most likely an issue in crc32.c. -- You are receiving this mail because: You are on the CC list for the bug.

Adding Tomas as he's been involved in zlib, incl. the code in question.

I would love to help but this patchset is dump from IBM for ppc and I really don't know much of what it does apart from fixing few off-by-one issues that we detected... -- You are receiving this mail because: You are on the CC list for the bug.

Well, I don't know much about this code either, but in this case I think a fix for this is fairly straight forward, to align the crc32_vpmsum function type in the Power specific patch with it's usage. See SR#714685.

The whole issue points out a concern of the impact that LTO can have outside of the package being modified.

This SR was accepted, and fixes the issue for me. -- You are receiving this mail because: You are on the CC list for the bug.
