Tested on hppa-unknown-linux-gnu and hppa64-hp-hpux11.11. Committed to trunk.

hppa: Fix LO_SUM DLTIND14R address support in PRINT_OPERAND_ADDRESS
This bug was hidden since LO_SUM DLTIND14R addresses are normally
handled by the A constraint in the move patterns.
2024-03-23 John David Anglin <dang...@gcc.gnu.org>
gcc/ChangeLog:
* config/pa/pa.cc (pa_output_global_address): Handle
UNSPEC_DLTIND14R addresses.
* config/pa/pa.h (PRINT_OPERAND_ADDRESS): Output "RT'" for
UNSPEC_DLTIND14R address.
