107280b6d5 b2/: rename "again" to "continue" 2012-05-22 15:44:31 -03:00

bb809b0d6c b2/: make "again" include the match; make "break" pop the stack 2012-05-22 15:29:27 -03:00

2ce2da5c30 b2/subst.c (resolve_jump): use pointer comparison instead of strcmp 
Both come from "unique".

21702781bc b2/: use re_nsub instead of maintaining our own equivalent 
We still need to count parentheses in prepare_re for the current index
into "units", but the rest can ue re_nsub.

148d5e85ac b2/: regexec puts first substring into pmatch[1] and not pmatch[0] 
Also clean up the hard-coded number of matches.

3d2eca34ff b2/: meta-variable $ for "previously matched variable" 
We need this for iterative processing of FN.

2946b830f1 b2/subst.c (prepare_re): fail on bad (#unit) syntax instead of ignoring 2012-05-22 12:07:41 -03:00
Werner Almesberger
d2171eba47 b2/: add "ignore" keyword for substitution rules 
This allows us to decide in the project-specific rules how to indicate
DNP/NC/DNS/... parts. In the original BOOM, F1 == NC was hard-coded.

2014e6053e b2/eval.c (decode_mult): also support "G" prefix 
Not that we'd need giga-anything anytime soon, but since all the rest
also recognizes G, we support it here for consistency.

fdac542592 b2/: add relop to struct param, in preparation of merge with struct var 2012-05-21 14:35:51 -03:00

3ad6c2c44b b2/: move all error handling from subex to subst 
This makes checking of variables more strict: a variable can only
be used in the right -hand side of an assignment if it has been
assigned by an unconditional predecessor or if it has been matched
by a parent.

Things that wouldn't work anymore:

REF=X* {
	FN=*V { X=Y }
	Z=$X	/* we can't be sure X=Y was taken */
}

FN=*R {
	X=$REF	/* no previous use of REF */
}

a34702cd8d b2/: move relational operators to relop.[ch] (for sharing) 
This also fixes a bug in dump_one_field, which switched > and >=

99e5777448 b2/: finish unit handling and move most of its processing to the match side 
The ${foo#unit} syntax didn't really make sense because it created
a large number of potential error conditions on the assignment side
and didn't help with finding compatible fields.

With all this moved to the match side, an invalid syntax simply causes
a mismatch.

1394c6b61c b2/: make top-level hierarchy item an action, not just a rule 
This allows the definition of optional global fields. For now, we (ab)use
this for FP (footprint).
