In GCC10 cp_walk_subtrees has been changed to walk template arguments. As the following testcase, that changed the mangling of some functions. I believe the previous behavior that find_abi_tags_r doesn't recurse into template args has been the correct one, but setting *walk_subtrees = 0 for the types and handling the types subtree walking manually in find_abi_tags_r looks too hard, there are a lot of subtrees and details what should and shouldn't be walked, both in tree.c (walk_type_fields there, which is static) and in cp_walk_subtrees itself. The following patch abuses the fact that *walk_subtrees is an int to tell cp_walk_subtrees it shouldn't walk the template args.

(mark_abi_tags_r): Likewise. * decl2.c (min_vis_r): Likewise. * tree.c (cp_walk_subtrees): If *walk_subtrees_p is 2, look through typedefs. gcc/testsuite/ChangeLog: PR c++/98481 * g++.dg/abi/abi-tag24.C: New test.

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*.
