In their arguments: - - A CLASS argument must be one of the constants defined in - mode-classes.def, less the leading MODE_ prefix; some statements - that take CLASS arguments have restrictions on which classes are - acceptable. For instance, INT. - - A MODE argument must be the printable name of a machine mode, - without quotation marks or trailing "mode".

Do not put a leading & - on the argument. - - An EXPR argument must be a syntactically valid C expression. - If an EXPR contains commas, you may need to write an extra pair of - parentheses around it, so it appears to be a single argument to the - statement. - - This file defines only those modes which are of use on almost all - machines.

Use in an ARCH-modes.def to reset the format - of one of the float modes defined in this file. - - PARTIAL_INT_MODE (MODE); - declares a mode of class PARTIAL_INT with the same size as - MODE (which must be an INT mode). The name of the new mode - is made by prefixing a P to the name MODE. This statement - may grow a PRECISION argument in the future. - - VECTOR_MODE (CLASS, MODE, COUNT); - Declare a vector mode whose component mode is MODE (of class - CLASS) with COUNT components. CLASS must be INT or FLOAT. - The name of the vector mode takes the form VnX where n is - COUNT in decimal and X is MODE. - - VECTOR_MODES (CLASS, WIDTH); - For all modes presently declared in class CLASS, construct - corresponding vector modes having width WIDTH. Modes whose - byte sizes do not evenly divide WIDTH are ignored, as are - modes that would produce vector modes with only one component, - and modes smaller than one byte (if CLASS is INT) or smaller - than two bytes (if CLASS is FLOAT). CLASS must be INT or - FLOAT. The names follow the same rule as VECTOR_MODE uses. - - COMPLEX_MODES (CLASS); - For all modes presently declared in class CLASS, construct - corresponding complex modes. Modes smaller than one byte - are ignored. For FLOAT modes, the names are derived by - replacing the 'F' in the mode name with a 'C'. (It is an - error if there is no 'F'. For INT modes, the names are - derived by prefixing a C to the name. - - 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 - once after processing all command line options, and should - evaluate to the desired byte size, alignment, or format. - - Unlike a FORMAT argument, if you are adjusting a float format - you must put an & in front of the name of each format structure. - - Note: If a mode is ever made which is more than 255 bytes wide, - machmode.h and genmodes.c will have to be changed to allocate - more space for the mode_size and mode_alignment arrays. */ - -/* VOIDmode is used when no mode needs to be specified, - as for example on CONST_INT RTL expressions. */ -RANDOM_MODE (VOID); - -/* BLKmode is used for structures, arrays, etc. - that fit no more specific mode. */ -RANDOM_MODE (BLK); - -/* Single bit mode used for booleans. */ -FRACTIONAL_INT_MODE (BI, 1, 1); - -/* Basic integer modes.
