Release20180206 | ||
=============== | ||
|
||
Here you can download the latest public release of MLton, version 20180206. | ||
|
||
== Changes since the last public release == | ||
|
||
* Compiler. | ||
** Added an experimental LLVM codegen (`-codegen llvm`); requires LLVM tools | ||
(`llvm-as`, `opt`, `llc`) version ≥ 3.7. | ||
** Made many substantial cosmetic improvements to front-end diagnostic | ||
messages, especially with respect to source location regions, type inference | ||
for `fun` and `val rec` declarations, signature constraints applied to a | ||
structure, `sharing type` specifications and `where type` signature | ||
expressions, type constructor or type variable escaping scope, and | ||
nonexhaustive pattern matching. | ||
** Fixed minor bugs with exception replication, precedence parsing of function | ||
clauses, and simultaneous `sharing` of multiple structures. | ||
** Made compilation deterministic (eliminate output executable name from | ||
compile-time specified `@MLton` runtime arguments; deterministically generate | ||
magic constant for executable). | ||
** Updated `-show-basis` (recursively expand structures in environments, | ||
displaying components with long identifiers; append `(* @ region *)` | ||
annotations to items shown in environment). | ||
** Forced amd64 codegen to generate PIC on amd64-linux targets. | ||
* Runtime. | ||
** Added `gc-summary-file file` runtime option. | ||
** Reorganized runtime support for `IntInf` operations so that programs that | ||
do not use `IntInf` compile to executables with no residual dependency on GMP. | ||
** Changed heap representation to store forwarding pointer for an object in | ||
the object header (rather than in the object data and setting the header to a | ||
sentinel value). | ||
* Language. | ||
** Added support for selected SuccessorML features; see | ||
http://mlton.org/SuccessorML for details. | ||
** Added `(*#showBasis "file" *)` directive; see | ||
http://mlton.org/ShowBasisDirective for details. | ||
** FFI: | ||
*** Added `pure`, `impure`, and `reentrant` attributes to `_import`. An | ||
unattributed `_import` is treated as `impure`. A `pure` `_import` may be | ||
subject to more aggressive optimizations (common subexpression elimination, | ||
dead-code elimination). An `_import`-ed C function that (directly or | ||
indirectly) calls an `_export`-ed SML function should be attributed | ||
`reentrant`. | ||
** ML Basis annotations. | ||
*** Added `allowSuccessorML {false|true}` to enable all SuccessorML features | ||
and other annotations to enable specific SuccessorML features; see | ||
http://mlton.org/SuccessorML for details. | ||
*** Split `nonexhaustiveMatch {warn|error|igore}` and `redundantMatch | ||
{warn|error|ignore}` into `nonexhaustiveMatch` and `redundantMatch` | ||
(controls diagnostics for `case` expressions, `fn` expressions, and `fun` | ||
declarations (which may raise `Match` on failure)) and `nonexhaustiveBind` | ||
and `redundantBind` (controls diagnostics for `val` declarations (which may | ||
raise `Bind` on failure)). | ||
*** Added `valrecConstr {warn|error|ignore}` to report when a `val rec` (or | ||
`fun`) declaration redefines an identifier that previously had constructor | ||
status. | ||
* Libraries. | ||
** Basis Library. | ||
*** Improved performance of `Array.copy`, `Array.copyVec`, `Vector.append`, | ||
`String.^`, `String.concat`, `String.concatWith`, and other related | ||
functions by using `memmove` rather than element-by-element constructions. | ||
** `Unsafe` structure. | ||
*** Added unsafe operations for array uninitialization and raw arrays; see | ||
https://github.com/MLton/mlton/pull/207 for details. | ||
** Other libraries. | ||
*** Updated: ckit library, MLLPT library, MLRISC library, SML/NJ library | ||
* Tools. | ||
** mlnlffigen | ||
*** Updated to warn and skip (rather than abort) when encountering functions | ||
with `struct`/`union` argument or return type. | ||
