Estimated hours taken: 0.5 compiler/intermod.m: Append the variable numbers to variables in the clauses written to `.opt' files. This fixes a bug which caused type errors to be reported for predicates in a `.opt' file. The problem was that the names of the DCG variables inside a DCG pred expression clashed with the DCG variables of the enclosing clause. tests/valid/Mmakefile: tests/valid/intermod_dcg_bug.m: tests/valid/intermod_dcg_bug2.m: Test case.

% Mercury ROTD 2/8/2000 reported a type error when typechecking
|
|
% the clauses for foo/2 from intermod_dcg_bug2.opt.
|
|
% The problem was that the DCG arguments introduced for the
|
|
% DCG pred expressions clashed with the DCG arguments for
|
|
% the enclosing clauses. The solution was to add variable numbers
|
|
% to clauses in `.opt' files.
