Re: PR/14899 patch ping^2


It is not. It is created from V2SI_type_node :-/ in config/rs6000/rs6000.c; my template specialization testcase still fails without these two lines.

Then lets fix the rs6000 back end.

How? What type shall I base the opaque type on? I thought about void, but then I have to special case build_vector_type because IIRC sizeof(void)=GET_MODE_SIZE(VOIDmode)=0. It seems like useless complication for a feature that almost nobody uses and probably nobody has ever put much care in designing---surely more complicated than two lines in comptypes plus three for a comment.
