The change seems correct. I guess we might worry about the performance cost. Although I don't remember ever seeing CSE showing up as a hotspot in a profile, so it's probably fine.
Yeah, I agree. |
* Fix ghost locations in modular extension AST nodes * Add missing ghostification Thank you, Carl! * Comment update about ghostiness (+ word-wrapping) * Add ghostify function (#1) * Add `Location.ghostify` * Update the parser's `make_ghost` to save an allocation in some cases * Promote parser.ml * Mark the inner mutable arrays for iarrays as ghost * Add comment about ghostification for comprehensions * Explain that ppxlib is where the ghostiness requirement is enforced * Use `Ast_helper.default_loc` to default the generated locations * Restore propagating the location, now via `Ast_helper.default_loc` * Drop obsolete comment * Rewrite advisory comment about locations
* new solver * better printing * remove solver_mono from mode_intf * document solver_polarized * address some comments * address more comments * rename "constrain" to "zap" * rename constrain_legacy * make depend * make fmt * remove _intf.ml * use comonadic in env * Add Allow_Disallow, restricting types of Obj.magic * Fix type errors discovered in previous commit * Use Allow_disallow in more places * show soundness of allow_disallow * Prevent chance of forgetting the "sound" version * minor changes * Remove the Solver_polarized.morph type (#1) * adjust comments * remove address_of * more comments * make [log] non-optional * better comments * More fixes * bind temp results * add C.eq_morph * set_append_changes * compare Value with Alloc * more comments * warn about infinite lattices * Small simplification to set_obj * example of variable cycle * say "uniqueness_op" because monotonicity * rename set to lift * exhaustive match * inline unusual helper functions * fix rebase issues * Small simplification * some renaming and comments * more comment * remove un-needed assertions. * fix chamelon * make fmt * add file header comments * exhausive match * use ref for morph counting * Reorder in maybe_compose * switch from lift to map * avoid caml_curry * dedup in join and meet * better error message * fix tests * comments * inlining newvar_above/blow, and more uncurrying * remove ?logging * make sure arity is correct and avoid closure allocation * remove morphism counting * force inline to avoid caml_applyX * address comments * rename and phy eq in eq_morphvar * Small improvement to [eq_morphvar] * better comments about lattices * don't hint to use exclave when useless * fix type_argument * comments about inner_alloc_mode * magic for eq_obj and eq_morph * allow/disallow for Value.List * Add comment about actual vs expected * comment mode_argument * eq_morph doesn't take dst * Magic_equal * better comment about adjunction * abstraction in ctype * comment close_over and partial_apply * fix eta expansion bug * Alloc.Const.t is record, not tuple * Simplify interface to [close_over] * Generalize the type of close_over * fixed definition of partial adjoint * better comment about partial adjoint * even better comments * make fmt * bootstrap --------- Co-authored-by: Richard Eisenberg <[email protected]> Co-authored-by: Richard Eisenberg <[email protected]>
