Some builds on SPARC stop with a register spill error
Builds of some oi-userland components stop with a gcc error. For example, the build of sysutils/coreutils on SPARC hardware stops with this error:
.../coreutils-8.25/src/factor.c: In function 'prime2_p.part.2': .../coreutils-8.25/src/factor.c:1371:1: error: unable to find a register to spill in class 'I64_REGS'
This only happens with 32-bit SPARC builds. 64-bit SPARC builds or any builds on x86 hardware are not affected. Other components, database/percona-server-57 and xorriso, also have this same problem. It's due to a bug in the gcc optimizer on certain hardware platforms.
The solution, actually a workaround, is to reduce the optimization level for builds on those platforms.
