tests/hard_coded/*.m:
Rename modules as mentioned above.
In a few cases, where the main module's name itself had a suffix,
such as "_mod_a" or "_main", remove that suffix. This entails
renaming the .exp file as well. (In some cases, this meant that
the name of a helper module was "taken over" by the main module
of the test case.)
Update all references to the moved modules.
General updates to programming style, such as
- replacing DCG notation with state var notation
- replacing (C->T;E) with (if C then T else E)
- moving pred/func declarations to just before their code
- replacing io.write/io.nl sequences with io.write_line
- replacing io.print/io.nl sequences with io.print_line
- fixing too-long lines
- fixing grammar errors in comments
tests/hard_coded/Mmakefile:
tests/hard_coded/Mercury.options:
Update all references to the moved modules.
Enable the constant_prop_int test case. The fact that it wasn't enabled
before is probably an accident. (When constant_prop_int.m was created,
the test case was added to a list in the Mmakefile, but that list
was later removed due to never being referenced.)
tests/hard_coded/constant_prop_int.{m,exp}:
Delete the calls to shift operations with negative shift amounts,
since we have added a compile-time error for these since the test
was originally created.

Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.
Branches: main
Store double-precision `float' constructor arguments in unboxed form,
in high-level C grades on 32-bit platforms, i.e. `float' (and equivalent)
arguments may occupy two machine words.
As the C code generated by the MLDS back-end makes use of MR_Float variables
and parameters, float (un)boxing may be reduced substantially in many programs.
compiler/prog_data.m:
Add `double_word' as a new option for constructor argument widths,
only used for float arguments as yet.
compiler/make_hlds_passes.m:
Set constructor arguments to have `double_word' width if required,
and possible.
compiler/type_util.m:
Add helper predicate.
compiler/builtin_ops.m:
compiler/c_util.m:
compiler/llds.m:
Add two new binary operators used by the MLDS back-end.
compiler/arg_pack.m:
Handle `double_word' arguments.
compiler/ml_code_util.m:
Deciding whether or not a float constructor argument requires boxing
now depends on the width of the field.
compiler/ml_global_data.m:
When a float constant appears as an initialiser of a generic array
element, it is now always unboxed, irrespective of --unboxed-float.
compiler/ml_type_gen.m:
Take double-word arguments into account when generating structure
fields.
compiler/ml_unify_gen.m:
Handle double-word float constructor arguments in (de)constructions.
In some cases we break a float argument into its two words, so
generating two assignments statements or two separate rvals.
Take double-word arguments into account when calculating field offsets.
compiler/mlds_to_c.m:
The new binary operators require no changes here.
As a special case, write `MR_float_from_dword_ptr(&X)' instead of
`MR_float_from_dword(X, Y)' when X, Y are consecutive words within a
field. The definition of `MR_float_from_dword_ptr' is more
straightforward, and gcc produces better code than if we use the more
general `MR_float_from_dword'.
compiler/rtti_out.m:
For double-word arguments, generate MR_DuArgLocn structures with
MR_arg_bits set to -1.
compiler/rtti_to_mlds.m:
Handle double-word arguments in field offset calculation.
compiler/unify_gen.m:
Partially handle double_word arguments in LLDS back-end.
compiler/handle_options.m:
Set --unboxed-float when targetting Java, C# and Erlang.
compiler/structure_reuse.direct.choose_reuse.m:
Rename a predicate.
compiler/bytecode.m:
compiler/equiv_type.m:
compiler/equiv_type_hlds.m:
compiler/llds_to_x86_64.m:
compiler/mlds_to_gcc.m:
compiler/mlds_to_il.m:
compiler/opt_debug.m:
Conform to changes.
library/construct.m:
library/store.m:
Handle double-word constructor arguments.
runtime/mercury_conf.h.in:
Clarify what `MR_BOXED_FLOAT' now means.
runtime/mercury_float.h:
Add helper macros for converting between doubles and word/dwords.
runtime/mercury_deconstruct.c:
runtime/mercury_deconstruct.h:
Add a macro `MR_arg_value' and a helper function to extract a
constructor argument value. This replaces `MR_unpack_arg'.
runtime/mercury_type_info.h:
Remove `MR_unpack_arg'.
Document that MR_DuArgLocn.MR_arg_bits may be -1.
runtime/mercury_deconstruct_macros.h:
runtime/mercury_deep_copy_body.h:
runtime/mercury_ml_arg_body.h:
runtime/mercury_table_type_body.h:
runtime/mercury_tabling.c:
runtime/mercury_type_info.c:
Handle double-word constructor arguments.
