Use the recently added --trans-opt-deps-spec option to break cycles in
the trans-opt dependency graph for the standard library. This enables
more parallelism when making the .trans_opt files; it now takes about
half as long as before.
Ordering modules sensibly, so that .trans_opt files are created in a
logical order, also improves analysis results for many predicates and
functions. The only results which show a regression with this change are
for deprecated forwarding predicates/functions.
In future, we will probably be able to trim more dependencies to further
improve parallelism, without impacting analysis results.
configure.ac:
Check that the bootstrap compiler supports --trans-opt-deps-spec.
library/mer_std.trans_opt_deps_spec:
Add the spec file that adjusts dependencies in the trans-opt
dependency graph.
library/INTER_FLAGS:
Use the --trans-opt-deps-spec option when building with mmake.
scripts/prepare_install_dir.in:
tools/binary:
tools/bootcheck:
tools/unary:
Copy mer_std.trans_opt_deps_spec when preparing a copy of the
library directory.
This directory, mercury/tools, contains scripts that are not intended for use by users. The scripts here are used by the Mercury developers for maintaining the Mercury compiler.
