◆ get_best_mode()
|
extern |
Find the best mode to use to access a bit field.
Find the best machine mode to use when referencing a bit field of length BITSIZE bits starting at BITPOS. BITREGION_START is the bit position of the first bit in this sequence of bit fields. BITREGION_END is the last bit in this sequence. If these two fields are non-zero, we should restrict the memory access to that range. Otherwise, we are allowed to touch any adjacent non bit-fields. The chosen mode must have no more than LARGEST_MODE_BITSIZE bits. INT_MAX is a suitable value for LARGEST_MODE_BITSIZE if the caller doesn't want to apply a specific limit. If no mode meets all these conditions, we return VOIDmode. The underlying object is known to be aligned to a boundary of ALIGN bits. If VOLATILEP is false and SLOW_BYTE_ACCESS is false, we return the smallest mode meeting these conditions. If VOLATILEP is false and SLOW_BYTE_ACCESS is true, we return the largest mode (but a mode no wider than UNITS_PER_WORD) that meets all the conditions. If VOLATILEP is true the narrow_volatile_bitfields target hook is used to decide which of the above modes should be used.

Get the next wider mode (eg, QI -> HI -> SI -> DI -> TI
or { HF, BF } -> SF -> DF -> XF -> TF).
This is similar to GET_MODE_NEXT_MODE, but while GET_MODE_NEXT_MODE
can include mode that have the same precision (e.g.
GET_MODE_NEXT_MODE (HFmode) can be BFmode even when both have the same
precision), this one will skip those. And always VOIDmode for
modes whose class is !CLASS_HAS_WIDER_MODES_P.
