Changes to the Mercury compiler
-------------------------------
* We have fixed a bug where `--warn-unused-imports` did not warn about
unused modules that are also imported by an ancestor of the current module.
* We have added a new option `--warn-ambiguous-pragmas`
that tells the compiler to generate warnings for pragmas that specify
a name/arity pair, when there is both a predicate and a function
with that name and arity, and the pragma does not specify which one
it is for.
* The deprecated option `--trail-segments` has been deleted and the grade
component `trseg` is no longer accepted as a synonym for `tr`.
* `--javac-flags` is now accepted as a synonym for `--java-flags`. Similarly
`--javac-flag` is now accepted as a synonym for `--java-flags`.
* The new options `--java-runtime-flags` and `--java-runtime-flags` can be
used to set flags for the Java interpreter in the launcher shell scripts or
batch files generated by the compiler when creating executables in the `java`
grade.
Portability improvements
------------------------
* We have updated the script `tools/configure_cross` to support
cross-compiling using clang.
Changes to the extras distribution
----------------------------------
* We have deleted the `old_term_parser` library.
NEWS for Mercury 22.01.4
========================
This is a bug-fix release.
* We have fixed and clarified the behaviour of the following `string`
module predicates when called on a string containing ill-formed code
unit sequences:
- pred `all_match/2`
- pred `index_next_repl/5`
- pred `unsafe_index_next_repl/5`
- pred `prev_index_repl/5`
- pred `unsafe_prev_index_repl/5`
NEWS for Mercury 22.01.3
========================
This is a bug-fix release.
* [Github issue #103]. We have disabled the use of some GCC optimizations
that were causing segmentation faults in code compiled in the `asm_fast`
grades with GCC versions 11 and 12 on x86_64 systems.
NEWS for Mercury 22.01.2
========================
This is a bug-fix release.
* [Mantis bug #558]. We have fixed a bug that was causing some of the
manual pages to sometimes build incorrectly.
* [Mantis bug #560]. We have disabled the use of the `asm_fast*` grades on
AArch64 when using GCC 9+ due to incompatibilities with position-independent
code.
* We have fixed a bug that was causing assertion failures or segmentation
violations in the Mercury runtime on AArch64 systems with versions of
GCC before 10.
* [Github issue #102]. We have disabled the use of the GCC option
`-Warray-bounds` for GCC version 12 and onwards. This is due to GCC
emitting spurious warnings when that option is enabled. (The use of
that option was already disabled for GCC versions 9-11.)
NEWS for Mercury 22.01.1
========================
This is a bug-fix release.
* [Mantis bug #557]. We have fixed a bug in module qualification that was
causing the compiler to fail without printing an error message.
NEWS for Mercury 22.01
======================
Changes that may break compatibility
------------------------------------
* We have removed `is` as a synonym for unification.
* We have reserved `=<`/2 as a type name.
* A term with a top-level functor `coerce/1` is now treated as a
type conversion expression. To call a function named `coerce/1`,
you can module qualify the name at the call site,
or wrap parentheses around the name, e.g. `(coerce)(Arg)`.
* We have renamed the `lexer` and `parser` modules of the Mercury standard
library to `mercury_term_lexer` and `mercury_term_parser` respectively.
* We have made slight changes to the names and/or the functionality
of several predicates in the `getopt` and `getopt_io` modules.
* We have removed the legacy support for the Alpha architecture.
* We have dropped support for macOS 10.8 and earlier.
* We have removed the Erlang backend as it was unmaintained.
Changes to the Mercury standard library

- func `bsearch/3` (replacement: `binary_search/3`)
- pred `bsearch/4` (replacement: `binary_search/4`)
- func `least_index/1` (replacement: `min/1`)
- func `greatest_index/1` (replacement: `max/1`)
* The following predicate has been added:
- pred `generate_foldl2/7`
### Changes to the `array2d` module

- func `unsafe_lookup/3` (synonym for `Array ^ unsafe_elem(R, C)`)
- pred `unsafe_lookup/4` (synonym for `Array ^ unsafe_elem(R, C)`)
* The `lists/1` function now returns an empty list for a 0x0 array.
### Changes to the `assoc_list` module
* The following predicates and functions have been added:
- func `common_subset/2`

- func `to_set_without_duplicates/1` (replacement: func `to_set/1`)
- pred `to_set_without_duplicates/2` (replacement: func `to_set/1`)

- pred `record_arguments/8`

- pred `process_options_track_io/9`
- pred `process_options_userdata/8`
- pred `process_options_userdata_io/10`
The ones whose names have an `_io` suffix do the same jobs as the
corresponding predicates without the `_io` suffix, with the exception
that they also have a pair of I/O state arguments that allow them
to implement `file_special` options. This functionality used to be
available only from the `getopt_io` module.
* The following predicates have had their argument types changed:
- pred `process_options/6`
- pred `process_options/7`
- pred `process_options_track/7`
All these predicates used to return error indications in the form of a
simple string. They now return error indications using the existing
structured type `option_error`, which can be converted into a string
on demand.
* The following predicates have been deleted:
- pred `process_options_se/6`
- pred `process_options_se/7`
- pred `process_options_track_se/7`
Their functionality is now available from the predicates with the same name
minus the `_se` suffix.
