Here ever since r12-6022-gbb2a7f80a98de3 we stopped deeming the partial specialization #2 to be more specialized than #1 ultimately because dependent operator expressions now have a DEPENDENT_OPERATOR_TYPE type instead of an empty type, and this made unify stop deducing T(2) == 1 for K during partial ordering for #1 and #2. This minimal patch fixes this by making the relevant logic in unify treat DEPENDENT_OPERATOR_TYPE like an empty type. PR c++/105425 gcc/cp/ChangeLog: * pt.cc (unify) <case TEMPLATE_PARM_INDEX>: Treat DEPENDENT_OPERATOR_TYPE like an empty type. gcc/testsuite/ChangeLog: * g++.dg/template/partial-specialization13.C: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
