--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note, I guess this is related to PR94366 and r12-438-g1580fc764423bf89e9b which
was fixing it for non-SIMT and quite possibly left out the SIMT stuff out.
Using the TRUTH_{AND,OR}_EXPR instead of TRUTH_{AND,OR}IF_EXPR ought to be
fine,
it is only merging the private vars into the original var, so neither has
really side-effects, all we want is that we are actually merging orig = (orig
!= 0) & (private != 0) rather than orig & private etc.
