--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I'd say this is a tree-outof-ssa.c bug, in elim_create it calls get_temp_reg on a SSA_NAME which has VECTOR_TYPE with one SFmode element, and as SPARC backend doesn't have V1SFmode, it has BLKmode. Creating a BLKmode pseudo of course doesn't work too well.
