looks sane, but the partitioning not:

Callgraph/varpool at WPA time:

baz/1 @0x7ffff5a257e0 (asm: baz) availability:not_available reachable
  called by: main/0 (1.00 per call)

Partitions:

Writing partition t2.o to file /tmp/ccZbL7rX.ltrans0.o, 0 insns
cgraph nodes:
varpool nodes: cfliteKeyCallBacks
Writing partition t1.o to file /tmp/ccZbL7rX.ltrans1.o, 5 insns
cgraph nodes: main/0
varpool nodes:

where is the varpool/alias node for cfliteValueCallBacks?
