From: David Malcolm Date: Fri, 24 Jan 2020 21:31:21 +0000 (+0000) Subject: analyzer: fix build with gcc 4.4 (PR 93276) X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=26d949c8c7a757df891ce79162b9bf15087418c6;p=gcc.git analyzer: fix build with gcc 4.4 (PR 93276) 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".
