This should fix Mantis bug #514. runtime/mercury_builtin_types_proc_layouts.h: Fix the first problem: refer to four type constructors defined in private_builtin.m by their correct arities, so that the proc layout structures we generate for their unify and compare predicates get generated with the correct names and contents. The arities were probably correct when the code was written; we changed them from 1 to 0 at some point, and simply forgot to update all the affected places. runtime/mercury_stack_layout.h: Fix the second problem: add "extern" to the declarations of those proc layout structures. Without the "extern", compilers defaulting the -fcommon will place these structures into common storage, which can be used as *definitions*. With the "extern", compilers should do the right thing whether or not they default to -fcommon. runtime/mercury_unify_compare_body.h: Conform to the change in mercury_builtin_types_proc_layouts.h: refer to the affected four types using the correct arities.
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.
README files
The Mercury compiler has a number of 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
-
Platforms
-
Cross compilation
Other information
See the current release notes for the latest stable release. The history file is relevant if you want to find out more about the past development of Mercury. News lists any current or future enhancements (but this isn't always up-to-date). The limitations file lists a number of 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.
