The below is from a ports-mgmt/poudriere-devel run under FreeBSD head
-r344825 on an old PowerMac G5 (2 sockets, 2 cores each, powerpc64).
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. If the wide vector op is eventually going to be expanded to
// scalar libcalls, then unroll into scalar ops now to avoid unnecessary
// libcalls on the undef elements. We are assuming that if the scalar op
// requires expanding, then the vector op needs expanding too.
EVT VT = N->getValueType(0);
if (TLI.isOperationExpand(N->getOpcode(), VT.getScalarType())) {
EVT WideVecVT = TLI.getTypeToTransformTo(*DAG.getContext(), VT);
assert(!TLI.isOperationLegalOrCustom(N->getOpcode(), WideVecVT) &&
"Target supports vector op, but scalar requires expansion?");
Res = DAG.UnrollVectorOp(N, WideVecVT.getVectorNumElements());
break;
}
