        PR middle-end/32889
        PR target/34091
        * pa.md: Consolidate HImode and QImode move patterns into one pattern
        each, eliminating floating-point alternatives.
        * pa-protos.h (pa_cannot_change_mode_class, pa_modes_tieable_p):
        Declare functions.
        * pa-64.h (SECONDARY_MEMORY_NEEDED): Define here.
        * pa.c (pa_secondary_reload): Use an intermediate general register
        for copies to/from floating-point register classes.  Simplify code
        SHIFT_REGS class.  Provide additional comments.
        (pa_cannot_change_mode_class, pa_modes_tieable_p): New functions.
        * pa.h (MODES_TIEABLE_P): Use pa_modes_tieable_p.
        (SECONDARY_MEMORY_NEEDED): Delete define.
        (INT14_OK_STRICT): Define.
        (MODE_OK_FOR_SCALED_INDEXING_P): Allow SFmode and DFmode when using
        soft float.
        (MODE_OK_FOR_UNSCALED_INDEXING_P): Likewise.
        (GO_IF_LEGITIMATE_ADDRESS): Use INT14_OK_STRICT in REG+D case for
        SFmode and DFmode.
        (LEGITIMIZE_RELOAD_ADDRESS): Use INT14_OK_STRICT in mask selection.
        Align DImode offsets when generating 64-bit code.
        * pa32-regs.h (VALID_FP_MODE_P): Remove QImode and HImode.
        (CANNOT_CHANGE_MODE_CLASS): Define.
        * pa64-regs.h (VALID_FP_MODE_P): Remove QImode and HImode.
        (CANNOT_CHANGE_MODE_CLASS): Define using pa_cannot_change_mode_class.
