rtl.c: Define CONST_DOUBLE_FORMAT to the appropriate format for a CONST_DOUBLE...
1999-08-27 13:27 -0700 Zack Weinberg <zack@bitmover.com>
* rtl.c: Define CONST_DOUBLE_FORMAT to the appropriate format
for a CONST_DOUBLE, at compile time. Initialize rtx_length
and class_narrowest_mode at compile time. Kill init_rtl.
Mark rtx_length, mode_class, mode_size, mode_unit_size,
mode_wider_mode, mode_mask_array, class_narrowest_mode, and
rtx_format as const. Kill all references to EXTRA_CC_MODES or
EXTRA_CC_NAMES.
* rtl.def (CONST_DOUBLE): Use CONST_DOUBLE_FORMAT macro for
format.
* rtl.h: Declare rtx_length and rtx_format as const.
* machmode.def: Define CC(). Use CC() to define CCmode. If
EXTRA_CC_MODES is defined, expand it here.
* machmode.h: Declare mode_class, mode_size, mode_unit_size,
mode_wider_mode, mode_mask_array, and class_narrowest_mode as
const. Kill all references to EXTRA_CC_MODES.
* toplev.c: Don't prototype or call init_rtl.
* optabs.c: Don't call init_mov_optab.
* genemit.c: Don't generate init_mov_optab. Don't call
init_rtl.
* gengenrtl.c: Duplicate calculation of CONST_DOUBLE_FORMAT
here.
* genattr.c, genattrtab.c, gencodes.c, genconfig.c,
genextract.c, genflags.c, genopinit.c, genoutput.c, genpeep.c,
genrecog.c: Don't call init_rtl.
* arc.h, arm.h, c4x.h, i386.h, i960.h, m88k.h, pa.h, pdp11.h,
rs6000.h, sparc.h: Don't define EXTRA_CC_NAMES. Use CC() in
definition of EXTRA_CC_MODES.
* md.texi: Kill ref to EXTRA_CC_NAMES.
* tm.texi: Document new way to define EXTRA_CC_MODES.
* genrecog.c: Do not look up the name of a define_split.
(Unrelated bugfix.)
