| 2017-07-10 | Further performance improvements to typechecker | Alasdair Armstrong | |

| 2017-07-03 | Added records to checker | Alasdair Armstrong | |

| 2017-06-30 | Split bit patterns for monomorphisation, do equality checks | Brian Campbell | |
| (e.g., for some ARM decoding functions) | |||
| 2017-06-30 | Added flow types to new typechecker | Alasdair Armstrong | |
| Added preliminary support for flow types, so we can typecheck things like: default Order inc val forall Num 'n, Num 'm, Num 'o, Num 'p. ([|'n:'m|], [|'o:'p|]) -> [|'n+'o:'m+'p|] effect pure add_range val forall Num 'n, Num 'm, Num 'o, Num 'p. ([|'n:'m|], [|'o:'p|]) -> [|'n-'p:'m-'o|] effect pure sub_range val forall Num 'n, Num 'm, Num 'o. ([|'n:'m|], [:'o:]) -> bool effect pure lt_range_atom val forall Num 'n, Num 'm, Num 'o. ([:'n:], [|'m:'o|]) -> bool effect pure lt_atom_range overload (deinfix +) [add_range] overload (deinfix -) [sub_range] overload (deinfix <) [lt_atom_range; lt_range_atom] function ([|63|]) branch (([|63|]) x) = { y := x; if (y < 32) then { y := 31; y + 32 } else y - 32 } Currently how this works is that the if condition is lifted to a typ modifying function that applies to the type of the variables appearing in the condition provided it satisfies some ad-hoc conditions. As can be seen above, it does require that the initial environment for the typechecker is set up with the correct definitions | |||
| 2017-06-29 | Rewrite bitvector patterns | Thomas Bauereiss | |
| Seems to work for CHERI-MIPS, but still a few things to be done, e.g. collecting let bindings for variables bound in bitvector patterns | |||
| 2017-06-29 | Added a large test case to the test-suite | Alasdair Armstrong | |
| Commented out some buggy re-sugaring logic from pretty_print_common where it re-sugared vectors incorrectly Fixed a bug where the type checker forgot to preserve type signatures in top-level letbinds | |||
| 2017-06-29 | Created prelude.sail for initial typing environment | Alasdair Armstrong | |
| Other things: * Cleaned up several files a bit * Fixed a bug in the parser where (deinfix |) got parsed as (definfix ||) * Turned of the irritating auto-indent in sail-mode.el | |||
