Hi Richard,


   The patch below is a fix for this problem, although I am not sure if
   it is the correct fix.  The patch selects the corresponding SFmode
   variant of the DFmode vector type when flag_short_doubles is enabled.
Maybe a better patch would be to disallow these builtins when using an
   ABI breaking option ?




I think the option should be simply removed...



Tempting - but we are in stage 3...  My patch at least fixes the ICE for
now.


Yeah, but is it a complete fix for all the -fshort-double issues?
I vote for removing it given that it appears not to have worked for several releases (PR60410). It is a target specific option really (m68hc11 judging by one entry in ChangeLog-2001).
