Add mmc --make --track-flags:
--track-flags
With `--make', keep track of the options used when compiling
each module. If an option for a module is added or removed,
`mmc --make' will then know to recompile the module even if the
timestamp on the file itself has not changed. Warning and
verbosity options are not tracked.
The motivation was to be able to set the execution trace level on selected
modules by editing Mercury.options, without needing to manually touch the
affected files afterwards to force recompilation. It's probably useful for
anyone that's worried about consistent builds.
The implementation works by recording a hash of the option table which is the
product of the options set for each particular module in .track_flags files,
not a hash of the actual options passed by the user, which might be reordered
or redundant, etc. Hashes are used as they are much quicker to compare and
take less space (the full options tables are quite big).
compiler/options.m:
Add the new option.
Add a predicate to return options that shouldn't be tracked
(e.g. adding -v shouldn't cause everything to recompile).
compiler/make.m:
When --track-flags is enabled, write `.track_flags' files which need
to be changed.
compiler/make.dependencies.m:
When --track-flags is enabled, make compiled code files depend on the
`.track_flags' files.
compiler/make.program_target.m:
Delete .track_flags files on realclean.
compiler/make.module_target.m:
compiler/make.util.m:
Conform to changes above.
compiler/libs.m:
compiler/md4.m:
Add an implementation of the MD4 digest function to libs.
doc/user_guide.texi:
NEWS:
Document the new option.
Recommend `mmc --make' instead of `mmake' in the user guide.
library/term_io.m:
Avoid unnecessary memory allocation in should_atom_be_quoted.
