The following patch implements the /* FIXME reuse another field? */ comment on the lambda_expr member. I think (and asserts in the patch seem to confirm) CLASSTYPE_KEY_METHOD is only ever non-NULL for TYE_POLYMORPHIC_P and on the other side CLASSTYPE_LAMBDA_EXPR is only used on closure types which are never polymorphic. So, the patch just uses one member for both, with the accessor macros changed to be no longer lvalues and adding SET_* variants of the macros for setters. 2025-07-11 Jakub Jelinek <jakub@redhat.com> * cp-tree.h (struct lang_type): Add comment before key_method. Remove lambda_expr. (CLASSTYPE_KEY_METHOD): Give NULL_TREE if not TYPE_POLYMORPHIC_P. (SET_CLASSTYPE_KEY_METHOD): Define. (CLASSTYPE_LAMBDA_EXPR): Give NULL_TREE if TYPE_POLYMORPHIC_P. Use key_method member instead of lambda_expr. (SET_CLASSTYPE_LAMBDA_EXPR): Define. * class.cc (determine_key_method): Use SET_CLASSTYPE_KEY_METHOD macro. * decl.cc (xref_tag): Use SET_CLASSTYPE_LAMBDA_EXPR macro. * lambda.cc (begin_lambda_type): Likewise. * module.cc (trees_in::read_class_def): Use SET_CLASSTYPE_LAMBDA_EXPR and SET_CLASSTYPE_KEY_METHOD macros, assert lambda is NULL if TYPE_POLYMORPHIC_P and otherwise assert key_method is NULL.

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.
