--- Comment #13 from Steven Munroe <munroesj at gcc dot gnu.org> --- "We want to use plain TImode instead of V1TImode on newer cpus." Actually I disagree. We have vector __int128 in the ABI and with POWER10 a complete set arithmetic operations for 128-bit in VRs. Also this issue is not restricted to TImode. It also effects _Float128 (KFmode), _ibm128 (TFmode) and Libmvec for vector float/double. The proper and optimum handling of these "union transfers" has been broken in GCC for years. And I have grave reservations about the vague plans of small/fringe minority to subset the PowerISA for their convenience.
