c++: Nondeterministic concepts diagnostics [PR94830]
This patch makes the order in which template parameters appear in the
TREE_LIST returned by find_template_parameters deterministic between
runs.
The current nondeterminism is semantically harmless, but it has the
undesirable effect of causing some concepts diagnostics which print a
constraint's parameter mapping via pp_cxx_parameter_mapping to also be
nondeterministic, as in the testcases below.
gcc/cp/ChangeLog:
PR c++/94830
* pt.c (find_template_parameter_info::parm_list): New field.
(keep_template_parm): Use the new field to build up the
parameter list here instead of ...
(find_template_parameters): ... here. Return ftpi.parm_list.
gcc/testsuite/ChangeLog:
PR c++/94830
* g++.dg/concepts/diagnostics12.C: Clarify the dg-message now
that the corresponding diagnostic is deterministic.
* g++.dg/concepts/diagnostics13.C: New test.
