This patch fixes various build failures seen with gcc 4.4 gcc prior to 4.6 complains about: error: #pragma GCC diagnostic not allowed inside functions for various uses of PUSH_IGNORE_WFORMAT and POP_IGNORE_WFORMAT. This patch makes them a no-op with such compilers. The patch also fixes various errors with template base initializers and redundant uses of "typename" that older g++ implementations can't cope with. gcc/analyzer/ChangeLog: PR analyzer/93276 * analyzer.h (PUSH_IGNORE_WFORMAT, POP_IGNORE_WFORMAT): Guard these macros with GCC_VERSION >= 4006, making them no-op otherwise. * engine.cc (exploded_edge::exploded_edge): Specify template for base class initializer. (exploded_graph::add_edge): Specify template when chaining up to base class add_edge implementation. (viz_callgraph_node::dump_dot): Drop redundant "typename". (viz_callgraph_edge::viz_callgraph_edge): Specify template for base class initializer. * program-state.cc (sm_state_map::clone_with_remapping): Drop redundant "typename". (sm_state_map::print): Likewise. (sm_state_map::hash): Likewise. (sm_state_map::operator==): Likewise. (sm_state_map::remap_svalue_ids): Likewise. (sm_state_map::on_svalue_purge): Likewise. (sm_state_map::validate): Likewise. * program-state.h (sm_state_map::iterator_t): Likewise. * supergraph.h (superedge::superedge): Specify template for base class initializer. gcc/ChangeLog: PR analyzer/93276 * digraph.cc (test_edge::test_edge): Specify template for base class initializer.
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.
