first-order code.

034cde0a97 syntax/parse template: track syntax vs non-syntax pairs in template 
Allows generation of more specialized code (hopefully smaller
and faster).

Also clean up some other guide reps.

a827322128 syntax/parse template: change run-time strategy 
Instead of doing run-time interpretation of a "guide" tree,
generate code for procedure (using stx -> stx combinators).

1795b7af5f syntax/parse template: remove syntax-property handling 
Since template was written, Racket has added a notion of preserved
syntax properties.

2de80c8091 syntax/parse: fix ps->stx+index; fixes #1602 
Collapse CDR frames separated by ORD, POST, etc. For example,
(1 ORD 2 stx) should be same as (3 stx).

29c90350b2 Failed attempt at making metafunctions from syntax/parse/experimental/template and stxparse-info/parse/experimental/template compatible. I can manage to extract the binding from syntax/parse/…, but it seems to recognize a different struct (e.g. as if they were struct instances from two different phases) 2017-01-28 05:16:50 +01:00

c42aef881c Support for define/syntax-parse, including when there are multiple defines. Search for the most up-to-date list of current-pvars is done by performing a dichotomy over a set of sequentially numbered current-pvars-paramNNN. Closes FB case 180. 2017-01-28 05:16:41 +01:00
