+ DECIMAL FLOAT_MODE (MODE, BYTESIZE);
+ declares MODE to be of class DECIMAL_FLOAT and BYTESIZE bytes
+ wide. All of the bits of its representation are significant.
+
FRACTIONAL_FLOAT_MODE (MODE, PRECISION, BYTESIZE, FORMAT);
declares MODE to be of class FLOAT, BYTESIZE bytes wide in
storage, but with only PRECISION significant bits, using
floating point format FORMAT.
+ FRACT_MODE (MODE, BYTESIZE, FBIT);
+ declares MODE to be of class FRACT and BYTESIZE bytes wide
+ with FBIT fractional bits. There may be padding bits.
+
+ UFRACT_MODE (MODE, BYTESIZE, FBIT);
+ declares MODE to be of class UFRACT and BYTESIZE bytes wide
+ with FBIT fractional bits. There may be padding bits.
+
+ ACCUM_MODE (MODE, BYTESIZE, IBIT, FBIT);
+ declares MODE to be of class ACCUM and BYTESIZE bytes wide
+ with IBIT integral bits and FBIT fractional bits.
+ There may be padding bits.

RESET_FLOAT_FORMAT (MODE, FORMAT);
changes the format of MODE, which must be class FLOAT,
to FORMAT. Use in an ARCH-modes.def to reset the format
ADJUST_BYTESIZE (MODE, EXPR);
ADJUST_ALIGNMENT (MODE, EXPR);
ADJUST_FLOAT_FORMAT (MODE, EXPR);
- Arrange for the byte size, alignment, or floating point format
- of MODE to be adjustable at run time. EXPR will be executed
+ ADJUST_IBIT (MODE, EXPR);
+ ADJUST_FBIT (MODE, EXPR);
+ Arrange for the byte size, alignment, floating point format, ibit,
+ or fbit of MODE to be adjustable at run time. EXPR will be executed
once after processing all command line options, and should
- evaluate to the desired byte size, alignment, or format.
+ evaluate to the desired byte size, alignment, format, ibit or fbit.
Unlike a FORMAT argument, if you are adjusting a float format
you must put an & in front of the name of each format structure.
