It produces a series of functions named `get_attr_...', one for each insn
|
1991-10-24 18:21:48 +01:00
|
|
|
attribute. Each of these is given the rtx for an insn and returns a member
|
|
|
|
|
of the enum for the attribute.
|
|
|
|
|
|
|
|
|
|
These subroutines have the form of a `switch' on the INSN_CODE (via
|
|
|
|
|
`recog_memoized'). Each case either returns a constant attribute value
|
|
|
|
|
or a value that depends on tests on other attributes, the form of
|
|
|
|
|
operands, or some random C expression (encoded with a SYMBOL_REF
|
|
|
|
|
expression).
|
|
|
|
|
|
|
|
|
|
If the attribute `alternative', or a random C expression is present,
|
|
|
|
|
`constrain_operands' is called. If either of these cases of a reference to
|
1998-11-04 22:25:00 +01:00
|
|
|
an operand is found, `extract_insn' is called.

The special attribute `length' is also recognized. For this operand,
|
1991-10-24 18:21:48 +01:00
|
|
|
expressions involving the address of an operand or the current insn,
|
|
|
|
|
(address (pc)), are valid. In this case, an initial pass is made to
|
|
|
|
|
set all lengths that do not depend on address. Those that do are set to
|
|
|
|
|
the maximum length. Then each insn that depends on an address is checked
|
|
|
|
|
and possibly has its length changed. The process repeats until no further
|
|
|
|
|
changed are made. The resulting lengths are saved for use by
|
|
|
|
|
`get_attr_length'.

A special form of DEFINE_ATTR, where the expression for default value is a
|
|
|
|
|
CONST expression, indicates an attribute that is constant for a given run
|
|
|
|
|
of the compiler. The subroutine generated for these attributes has no
|
|
|
|
|
parameters as it does not depend on any particular insn. Constant
|
|
|
|
|
attributes are typically used to specify which variety of processor is
|
|
|
|
|
used.

This program works by keeping a list of possible values for each attribute.
|
|
|
|
|
These include the basic attribute choices, default values for attribute, and
|
|
|
|
|
all derived quantities.
|
|
|
|
|
|
|
|
|
|
As the description file is read, the definition for each insn is saved in a
|
|
|
|
|
`struct insn_def'. When the file reading is complete, a `struct insn_ent'
|
|
|
|
|
is created for each insn and chained to the corresponding attribute value,
|
|
|
|
|
either that specified, or the default.
|
|
|
|
|
|
|
|
|
|
An optimization phase is then run. This simplifies expressions for each
|
|
|
|
|
insn. EQ_ATTR tests are resolved, whenever possible, to a test that
|
|
|
|
|
indicates when the attribute has the specified value for the insn. This
|
|
|
|
|
avoids recursive calls during compilation.

The strategy used when processing DEFINE_DELAY definitions is to create
|
|
|
|
|
arbitrarily complex expressions and have the optimization simplify them.
|
1991-10-24 18:21:48 +01:00
|
|
|
|
|
|
|
|
Once optimization is complete, any required routines and definitions
|
1992-03-06 23:25:46 +01:00
|
|
|
will be written.
|
|
|
|
|
|
|
|
|
|
An optimization that is not yet implemented is to hoist the constant
|
|
|
|
|
expressions entirely out of the routines and definitions that are written.
|
|
|
|
|
A way to do this is to iterate over all possible combinations of values
|
|
|
|
|
for constant attributes and generate a set of functions for that given
|
|
|
|
|
combination. An initialization function would be written that evaluates
|
|
|
|
|
the attributes and installs the corresponding set of routines and
|
1992-05-07 01:13:18 +02:00
|
|
|
definitions (each would be accessed through a pointer).

There is one special case: If we see
|
|
|
|
|
(and (not (eq_attr "att" "v1"))
|
|
|
|
|
(eq_attr "att" "v2"))
|
|
|
|
|
this can be replaced by (eq_attr "att" "v2"). To do this we need to
|
|
|
|
|
replace the term, not anything in the AND tree. So we pass a pointer to
|
|
|
|
|
the term. */

delay slot ordinal, and a candidate insn. It returns nonzero if the

candidate can be placed in the specified delay slot of the insn.

handles normal delay slots, `eligible_for_annul_true' indicates that

the specified insn can be annulled if the branch is true, and likewise

for `eligible_for_annul_false'.
