/* Predicate handling.
|
|
|
|
|
|
|
|
|
|
We construct from the machine description a table mapping each
|
|
|
|
|
predicate to a list of the rtl codes it can possibly match. The
|
|
|
|
|
function 'maybe_both_true' uses it to deduce that there are no
|
|
|
|
|
expressions that can be matches by certain pairs of tree nodes.
|
|
|
|
|
Also, if a predicate can match only one code, we can hardwire that
|
|
|
|
|
code into the node testing the predicate.
|
|
|
|
|
|
|
|
|
|
Some predicates are flagged as special. validate_pattern will not
|
|
|
|
|
warn about modeless match_operand expressions if they have a
|
|
|
|
|
special predicate. Predicates that allow only constants are also
|
|
|
|
|
treated as special, for this purpose.
|
|
|
|
|
|
|
|
|
|
validate_pattern will warn about predicates that allow non-lvalues
|
|
|
|
|
when they appear in destination operands.
|
|
|
|
|
|
|
|
|
|
Calculating the set of rtx codes that can possibly be accepted by a
|
|
|
|
|
predicate expression EXP requires a three-state logic: any given
|
|
|
|
|
subexpression may definitively accept a code C (Y), definitively
|
|
|
|
|
reject a code C (N), or may have an indeterminate effect (I). N
|
|
|
|
|
and I is N; Y or I is Y; Y and I, N or I are both I. Here are full
|
|
|
|
|
truth tables.
|
|
|
|
|
|
|
|
|
|
a b a&b a|b
|
|
|

|
Y Y Y Y
|
|

|
|
I N N I
|
|
|
|
|
I I I I
|
|
|
|
|
|
|
|
|
|
We represent Y with 1, N with 0, I with 2. If any code is left in
|
|
|
|
|
an I state by the complete expression, we must assume that that
|
|
|
|
|
code can be accepted. */

(read_rtx): If read_rtx_1 returns 0, treat as EOF.
(read_rtx_1): If we get EOF when we were looking for an initial
open paren, return 0. Call read_conditions when appropriate.
* Makefile.in: Kill BUILD_EARLY_SUPPORT and all references to
dummy-conditions.o. Eliminate references to insn-conditions.o,
or change them to build/gencondmd.o, as appropriate. Remove
insn-constants.h from $(simple_generated_h) and insn-conditions.c
from $(simple_generated_c). For all files remaining in those
two lists, add insn-conditions.md to the generator command line.
Give insn-constants.h/s-constants their own rules. Add rules
for build/gencondmd.c, s-conditions, insn-conditions.md, s-condmd.
(build/read-rtl.o): Depend on gensupport.h.
(genprognormal): Include preds.
(genprogearly): Rename genprognoprint; only difference is now that
they don't link with $(BUILD_PRINT).
* dummy-conditions.c: Delete.
