When merging duplicate instantiations of function templates, currently read_function_def overwrites the arguments with that of the existing duplicate. This is problematic, however, since this means that the PARM_DECLs in the body of the function definition no longer match with the PARM_DECLs in the argument list, which causes issues when it comes to generating RTL. There doesn't seem to be any reason to do this replacement, so this patch removes that logic. PR c++/112588 gcc/cp/ChangeLog: * module.cc (trees_in::read_function_def): Don't overwrite arguments. gcc/testsuite/ChangeLog: * g++.dg/modules/merge-16.h: New test. * g++.dg/modules/merge-16_a.C: New test. * g++.dg/modules/merge-16_b.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.
