Proposed patch
TImode (and DImode on 32-bit targets) should be tied with other integer modes.
We allow HImode values in XMM registers, so on 64-bit targets, TImode can be
tied with HImode in both, integer and XMM registers. This will allow a register
in
(insn 228 230 227 2 (set (reg:TI 345)
(subreg:TI (reg:HI 389) 0)) "/app/example.cpp":6:5 94 {*movti_internal}
(expr_list:REG_DEAD (reg:HI 389)
(nil)))
to be accessed directly.
