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.
Mercury
Mercury is a logic/functional programming language which combines the clarity and the expressiveness of declarative programming with advanced static analysis and error detection features.
More information is available on the website's about pages, in other README files in the source code repository, and in the documentation.
Small sample programs written in Mercury can be found in the samples and extras directories of the source code repository.
README files
The Mercury compiler has two different backends and works on different operating systems. Specific information is contained in individual README files:
-
Bootstrapping discusses how to get Mercury installed.
This is important, as the Mercury compiler is written in Mercury.
-
C Low-level backend
This backend works well with GCC but also works with:
-
High-level backend targets
-
Supported operating systems
-
Other platform information
Other information
See the current release notes for the latest stable release. The news file lists any recent changes. The history file is relevant if you want to find out more about the past development of Mercury. The limitations file lists some ways in which the Mercury implementation does not yet meet its goals.
Information for developers
If you are considering contributing to the Mercury project, the website contains some documents that may be helpful. These include a document about contributions in general and specific information about contributing such as coding styles.
