Doug Gregor	d752f414d3	[Constraint solver] Rework solveImpl(Expr*) to return SolutionResult. ... SolutionResult better captures what can happen when solving a constraint system for the given expression occurs than the ad hoc SolutionKind return & small vector of Solution results. Also, try to make this logic less convoluted.	2020-01-26 12:05:43 -08:00
Doug Gregor	e06fb4bed3	[Constraint system] Capture "salvage" result in a self-contained data structure ... Rework the interface to ConstraintSystem::salvage() to (a) not require an existing set of solutions, which it overwrites anyway, (b) not depend on having a single expression as input, and (c) be clear with its client about whether the operation has already emitted a diagnostic vs. the client being expected to produce a diagnostic.	2019-11-18 16:34:01 -08:00
