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.
