build.log (mariadb-10.3.10)

Same build failure on mariadb-10.3.10.

[Comment 4 A. Wilcox (awilfox) 2019-07-06 21:58:12 UTC]

This isn't a ppc64 failure.  It may be on 64-bit hardware, but from the toolchain triplet and the failure, it's 32-bit PowerPC.

We're hitting this on Adélie as well, in 32-bit PowerPC.  It seems to be something with AltiVec.  Still investigating.

Remove "extra crc32" module from MariaDB 10.x

Okay.

First, if you are building for 32-bit PowerPC, ensure you 'setarch ppc' before running builds.  Not doing this will break a lot of build systems, but *especially* MariaDB.  That would fix the issue that the reporter is facing, as then MariaDB doesn't try to do POWER8 VMX things on 32-bit PowerPC.

However, the real bug is that MariaDB uses POWER8 VMX instructions unconditionally when CMAKE_SYSTEM_PROCESSOR is ppc64.  This will break any system that isn't a POWER8 (970/970fx, P5/P6/P7, etc).

Apply the patch I've attached to fix *that*.
