samples/c_interface/simpler_cplusplus_calls_mercury/Mmakefile:
As above.
compiler/mercury_compile_main.m:
Compiler invocations that generate an executable, and thus do linking,
should check that the selected grade's libraries are in fact available.
In non-"mmc --make" invocations, this is the job of mercury_compile_main.m.
Once upon a time, we used to do this once per compiler argument.
A diff later intended to change this so that the check was done
only once, and not repeated for every compiler argument, but it
did it wrong. It did add a single central check (the do-it-once part), but
- it added this check only in the case where --filenames-from-stdin
was not specified, and
- it did not delete the do-it-for-every-argument code.
For invocations with --filenames-from-stdin, the checks were still
needed, though only once. For invocations without --filenames-from-stdin,
the extra check was only repeated overhead. (The duplicate error messages
would have been deleted when they were sorted.)
Fix this by doing the check only once, whether --filenames-from-stdin
is specified or not.
Document why doing this is a reasonable thing to do. Add an XXX about
a possible improvement.
Resolve a conjecture in an old comment.
samples/c_interface/*:
Replace left over references to the old c_header_code pragma.
Replace some uses of '__' as a module qualifier.
Replace tabs with spaces.
Add some missing words.
docs/reference_manual.texi:
docs/user_guide.texi:
As above (and check that they are still current).
doc/mercury.html.in:
Update a link to the old Mercury homepage.
Update the markup style.
library/io.m:
As above.
library/io.error_util.m:
Delete the equivalent operation is_success/1 from here and
just use system_error_is_success/1 instead.
NEWS.md:
Announce the new predicate.
library/string.format.m:
Delete the old predicates for formatting ints as unsigned values;
these are now unused.
configure.ac:
Require the use of a compiler that does not generate references
to the deleted predicates.
compiler/introduced_call_table.m:
Delete the above predicates from the introduced call table.
library/string.m:
... in favor of the s/codepoint/code_point/ versions.
NEWS.md:
Mention that these predicates and functions have been marked obsolete.
Mention that all the X_to_doc functions in modules other than
pretty_printer.m have been marked obsolete in favour of the versions
in pretty_printer.m.
Standardize on indenting lists of function and predicate names
by four spaces, not three. (There were more than five times as many
that were indented by four than by three.)
compiler/typecheck_error_undef.m:
... only if that predicate or function was declared by the user.
If the compiler itself added the pred/func declaration implicitly
because it saw a clause for that pred/func, but then decided not to
add that clause to the HLDS after all because it had syntax errors,
then don't complain about the absence of a clause for a pred/func
that the user did not declare.
tests/invalid/state_vars_test3.err_exp:
Expect no complaint about a missing clause in the above situation.
library/string.m:
For each predicate and function whose name includes "codepoint",
- create a version in which "codepoint" is replaced by "code_point",
- make this version the main implementation, making the "codepoint"
versions forward to the "code_point" versions,
- add obsolete pragmas for the "codepoint" versions, though these are
commented out for now. This is so that an installed compiler containing
this change will already have the recommended alternative available
when the commenting-out is removed (maybe in a week or so).
NEWS.md:
Announce the new predicates and functions.

Replace all uses of the "codepoint" versions with the "code_point"
versions.
When writing out dependency files, the compiler would call
module_name_to_file_name often for the same pairs of module name and
file extension. Caching the results of those calls saves on
constructing temporary strings.
This change reduces the time to make dependencies in the compiler
directory from 2.40 seconds to 2.15 seconds on my machine.
compiler/write_deps_file.m:
Add a predicate make_module_file_name that caches calls to
module_name_to_file_name.
Thread the cache map through the predicates in this module.
Replace calls to module_name_to_file_name with calls to
make_module_file_name when appropriate.
Benchmarking on randomly generated digraphs shows a speedup of 30-40%.
The time to make dependencies in the compiler directory on my machine
is reduced from 3.65 seconds to 2.40 seconds.
library/digraph.m:
Rewrite digraph.compose more efficiently.
compiler/typecheck_errors.m:
Improve the diagnostics we generate for mismatches between actual and
expected types. If the mismatch was between a single actual type and
a single expected type, we already printed a message whose format
was specialized for that case, but in every other case, we fell back
to a more general but less readable error message template. Improve on this
by splitting the task into two halves, one for the actual type(s) and one
for the expected type(s), each of which generates simpler text if
there is only one such type.
Separate the actual type part of the diagnostic from the expected type part
using a semicolon instead of a comma, because we now use commas to
separate multiple actual types from each other, and multiple expected
types from each other.
Don't insist on putting a newline after the "type error:" part of the
diagnostic.
Do all of the above in just one predicate, factoring out code that
used to be duplicated.
Delete a function that has never been used. (I added it around 2008
for later use by a student working on software transactional memory,
but that use never happened.) This used to contain a third copy
of the code that was factored out.
For functions that used to take both a typecheck_info and a
type_error_clause_context, delete the latter argument, since the caller
invariably took it out of the typecheck_info that it also passed.
compiler/typecheck.m:
Don't pass now-unneeded type_error_clause_contexts.
compiler/typecheck_error_type_assign.m:
Fix typo in a field name.

This reduces the time to make dependencies in the compiler directory
from 5.85 seconds to 3.60 seconds on my machine.
compiler/write_deps_file.m:
Use set.list_to_set instead of calling set.insert in a loop.
library/fatter_sparse_bitset.m:
Add this version of fat_sparse_bitset.m, which stores *two* words
worth of bits in each cell, not one. This word would otherwise be unused,
because the Boehm-Demers-Weiser allocator rounds up requests for three
word cells to four.
library/MODULES_DOC:
library/library.m:
Add the new module to the list of library modules.
library/fat_sparse_bitset.m:
library/sparse_bitset.m:
library/tree_bitset.m:
Update the documentation of all these other bitset modules. Copy
the same basic introduction to all the relevant modules. Add documentation
of the differences to tree_bitset.m and fatter_sparse_bitset.m, with
a pointer in fat_sparse_bitset.m to fatter_sparse_bitset.m.
library/test_bitset.m:
Test the new module as well as the others.
tests/hard_coded/speedtest_bitset.m:
Extend the benchmarking of list_to_set operations to the new module.
To allow the benchmarking to be tough enough to be informative, comment
out the benchmarking of the old_list_to_set operations.
