I'll look into it. But it's really just Kaz' most recent tree with the three
additional patches.
I also just tried your latest tree and I'm still getting the subreg3 ICE there:
during RTL pass: subreg3
../../gcc/ipa-sra.cc: In function 'void
{anonymous}::isra_read_edge_summary(lto_input_block*, cgraph_edge*)':
../../gcc/ipa-sra.cc:2933:1: internal compiler error: in
decompose_multiword_subregs, at lower-subreg.cc:1731
