genmodes.c, [...]: New files.
* genmodes.c, mode-classes.def: New files.

* Makefile.in (extra_modes_file): New substitution variable.
(MACHMODE_H): No longer includes machmode.def or
@extra_modes_file@; instead, mode-classes.def and insn-modes.h.
(BUILD_RTL): Add $(BUILD_PREFIX)insn-modes.o.
(OBJS-common): Add insn-modes.o.
(STAGESTUFF): Add insn-modes.c, insn-modes.h, s-modes, and
genmodes$(build_exeext).
(insn-modes.o, insn-modes.c, insn-modes.h, s-modes, genmodes.o,
genmodes$(build_exeext), $(BUILD_PREFIX_1)insn-modes.o): New targets.
(s-genrtl): Don't depend on $(RTL_BASE_H).
(gengenrtl.o): Don't depend on coretypes.h, $(GTM_H), real.h,
or $(RTL_BASE_H); just rtl.def.
* gengenrtl.c: Don't include coretypes.h, tm.h, rtl.h, or
real.h. Give fake definition of CONST_DOUBLE_FORMAT and
substitute definition of NUM_RTX_CODE. Add casts to avoid
warnings.
* machmode.h: Include insn-modes.h, not machmode.def. Include
mode-classes.def to define enum mode_class. Tweak definitions
of GET_MODE_CLASS, GET_MODE_SIZE, GET_MODE_BITSIZE, GET_MODE_MASK,
GET_MODE_INNER, GET_MODE_WIDER_MODE, GET_CLASS_NARROWEST_MODE.
(inner_mode_array): Renamed mode_inner.
(mode_base_align): New.
* rtl.c (mode_name, mode_class, mode_bitsize, mode_size,
mode_unit_size, mode_wider_mode, mode_mask_array,
inner_mode_array, class_narrowest_mode): Delete definitions.
* stor-layout.c (get_mode_alignment): Use mode_base_align.
* real.h: Use MIN_MODE_FLOAT and MAX_MODE_FLOAT, not QFmode
and TFmode, in real_format_for_mode and REAL_MODE_FORMAT.
* config/ip2k/ip2k.h, config/iq2000/iq2000.h:
No need to define BITS_PER_UNIT.

/* Usually the size and mode come from the data type without change,
|
|
|
|
|
however, the front-end may set the explicit width of the field, so its
|
|
|
|
|
size may not be the same as the size of its type. This happens with
|
|
|
|
|
bitfields, of course (an `int' bitfield may be only 2 bits, say), but it
|
|
|
|
|
also happens with other fields. For example, the C++ front-end creates
|
|
|
|
|
zero-sized fields corresponding to empty base classes, and depends on
|
|
|
|
|
layout_type setting DECL_FIELD_BITPOS correctly for the field. Set the
|
2000-04-21 21:19:24 +02:00
|

|
|
size in bytes from the size in bits. If we have already set the mode,
|
|
|
|
|
don't set it again since we can be called twice for FIELD_DECLs. */
