/* This file defines all the MACHINE MODES used by GCC.
|
|
|
|
A machine mode specifies a size and format of data
|
|
at the machine level.
|
|
|
|
Each RTL expression has a machine mode.
|
|
|
|
At the syntax tree level, each ..._TYPE and each ..._DECL node
|
|
has a machine mode which describes data of that type or the
|
|
data of the variable declared. */
|
|
|
|
/* The first argument is the internal name of the machine mode
|
|
used in the C source.
|
|
By convention these are in UPPER_CASE, except for the word "mode".
|
|
|
|
The second argument is the name of the machine mode in the
|
|
external ASCII format used for reading and printing RTL and trees.
|
|
By convention these names in UPPER_CASE.
|
|
|
|
Third argument states the kind of representation:
|
|
MODE_INT - integer
|
|
MODE_FLOAT - floating
|
|
MODE_PARTIAL_INT - PQImode, PHImode, PSImode and PDImode
|
|
MODE_CC - modes used for representing the condition code in a register
|
|
MODE_COMPLEX_INT, MODE_COMPLEX_FLOAT - complex number
|
|
MODE_VECTOR_INT, MODE_VECTOR_FLOAT - vector
|
|
MODE_RANDOM - anything else
|
|
|
|
Fourth argument is the relative size of the object, in bits,
|
|
so we can have modes smaller than 1 byte.
|
|
|
|
Fifth argument is the relative size of the object, in bytes.
|
|
It is zero when the size is meaningless or not determined.
|
|
A byte's size is determined by BITS_PER_UNIT in tm.h.
|
|
|
|
Sixth arg is the relative size of subunits of the object.
|
|
It is same as the fifth argument except for complexes and vectors,
|
|
since they are really made of many equal size subunits.
|
|
|
|
Seventh arg is next wider natural mode of the same class.
|
|
0 if there is none. */
