moving v16sf reg with multiple sub-regs

Hi there, (B (BI have implemented a move of a v16sf type like this because it is held by 4 (Bv4sf registers: (B (B--- snip --- (B (B(define_expand "movv16sf" (B [(set (match_operand:V16SF 0 "nonimmediate_operand" "") (B (match_operand:V16SF 1 "general_operand" ""))] (B "" (B " if ((

Ah, ok, sorry about that, I read it as being the equivalent of the whole operation. I'll throw op1 in there, thanks again. Dylan "James E Wilson" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Dylan Cuthbert wrote: For the last parameter (equiv) of emit_n

Unless in gcc-world outermode has the meaning of innermode? (and vice versa) which.. from looking at some other source... perhaps it does.. :-/ "Dylan Cuthbert" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Ok, I think I found out why gen_subreg crashes here:
