Estimated hours taken: 2 Branches: main Improve the clarity of polymorphism.m further. compiler/polymorphism.m: When a data structure involving type variables has several versions which differ in which tvarset those type variables come from (the raw tvarset of a called predicate's pred_info, the renamed-apart version in which those type variables have been lifted into the caller's newly expanded tvarset, and the version in which the type variables in the types of the formal parameters been replaced with the actual (possibly polymorphic) types from the actual arguments), use a mnemonic prefix to distinguish them, not a numerical suffix of the kind we use for other kinds of transformations. Put the code handling foreign_procs into its own predicate, to make debugging easier. compiler/prog_data.m: Add field names to the class_constraints type, for use in polymorphism.m. compiler/type_util.m: Add a utility predicate, factoring out repeated code from polymorphism.m. library/varset.m: Clarify the documentation of varset__merge_subst.
Reportedly Mercury does not work on Solaris 2.5.1 if it is compiled with
gcc 2.7.x. It should however work fine on Solaris 2.5.1 if you compile
it with gcc 2.8, or if you use gcc 2.7.x with an earlier version of Solaris.
The binary distribution for Solaris that we distribute was compiled
with gcc 2.7.2, so if you have Solaris 2.5.1, you may need to compile
Mercury yourself from our source distribution.
("Solaris 2.x" is also known as "SunOS 5.x".)
