--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:1a830c0636472e47a7503a5ed879725149e2e728 commit r12-2685-g1a830c0636472e47a7503a5ed879725149e2e728 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Aug 3 12:44:17 2021 +0200 analyzer: Fix ICE on MD builtin [PR101721] The following testcase ICEs because DECL_FUNCTION_CODE asserts the builtin is BUILT_IN_NORMAL, but it sees a backend (MD) builtin instead. The FE, normal and MD builtin numbers overlap, so one should always check what kind of builtin it is before looking at specific codes. On the other side, region-model.cc has: if (fndecl_built_in_p (callee_fndecl, BUILT_IN_NORMAL) && gimple_builtin_call_types_compatible_p (call, callee_fndecl)) switch (DECL_UNCHECKED_FUNCTION_CODE (callee_fndecl)) which IMO should use DECL_FUNCTION_CODE instead, it checked first it is a normal builtin... 2021-08-03 Jakub Jelinek <ja...@redhat.com> PR analyzer/101721 * sm-malloc.cc (known_allocator_p): Only check DECL_FUNCTION_CODE on BUILT_IN_NORMAL builtins. * gcc.dg/analyzer/pr101721.c: New test.
