--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Wouldn't many spots in the middle-end be upset about the gimple clobber having a variable length type (both the MEM_REF on the lhs and corresponding type on the CONSTRUCTOR)? I think tree DCE should have everything it needs for the removals even without such CLOBBERs, except that it is harder but not impossible to find out which __builtin_stack_restore frees what.
