Doug Gregor	42b1ab6fbd	Introduce a LangOptions class to capture various type-checker-tweaking flags. For now, introduce bits to enable the constraint solver and to enable debugging of the constraint solver, and use those to eliminate the "useConstraintSolver" bit that was threaded through too much of the type checker. ...

Doug Gregor	81d8f27bde	When dumping constraints via TypeChecker::typeCheckExpression(), don't ... rely at all on the existing type checker. Instead, just fold sequence expressions (which are effectively a delayed parsing phase) and then hand off the expression to the constraint solver. Allows us to type-check expressions with operators, e.g., f + 1. Swift SVN r2793	2012-08-27 18:33:20 +00:00
Doug Gregor	0d7afbe5e0	Introduce an almost completely untested implementation of constraint ... generation from an expression that has not been type-checked. One can see the constraints introduced by an expression by using :dump_constraints <expression> within the REPL. We're still missing several major pieces of constraint generation: - We don't yet "open up" references to polymorphic types - We don't print out the child constraint systems in the dump, so it's not at all obvious what happens within overloading (and I'm not convinced I like my representation anyway) - There are no tests whatsoever - Member constraints are still very, very weird Swift SVN r2624	2012-08-13 22:59:41 +00:00
Eli Friedman	837fdf04fb	Always type-check immediately after a line is finished in the REPL. This isn't quite the same as how script mode works at the moment, but apparently it's way too confusing to delay type-checking errors. <rdar://problem/11296808> ... Swift SVN r1572	2012-04-23 23:53:28 +00:00
Eli Friedman	be602fcd05	Get rid of the implicit BraceStmt for the TranslationUnit; instead, have the TranslationUnit directly store a list of decls. ... Swift SVN r1521	2012-04-20 00:17:13 +00:00
Eli Friedman	acc17d69aa	Initial implementation of the "print" part of the REPL. ... Swift SVN r1484	2012-04-19 01:13:37 +00:00
Eli Friedman	cf10f0096e	Make the REPL allow mutually recursive functions spread across multiple lines, like we do in script mode. ... Swift SVN r1453	2012-04-18 01:20:38 +00:00
Eli Friedman	dc213bca76	Implement basic REPL under swift -repl. Known demo-blockers: need error recovery, need better brace/paren handling, need to implement the "print" part of REPL. ... Swift SVN r1452	2012-04-18 00:52:11 +00:00
Eli Friedman	37de44a35d	Implement changes to parsing/sema/etc so that we can implement a REPL and the main module parses the same way as a REPL. ... Next step: implement an actual REPL. Swift SVN r1441	2012-04-16 23:52:01 +00:00
