The /usr/ports is from head -r494751 . buildworld buildkernel was via devel/powerpc64-xtoolchain-gcc materials and system-clang (8.0.0) was built (and installed as cc/c++) as part of that. /usr/ports/base/binutils was used to supply the system binutils, including ld. (Running the PowerPC G5 for this context does require some hacks in /usr/src/ currently.) Being a poudriere-devel run, the /tmp/nir_constant_expressions-be5a21.* are not available (not recorded in the tar of the failure). (Too bad there is a mismatch betting poudriere's capture and where such files are placed.) But I do have a gdb based backtrace from the: work/mesa-18.3.2/src/compiler/cc.15701.core The assert was the one in: case ISD::FTRUNC: { // We're going to widen this vector op to a legal type by padding = with undef // elements.
