But sometimes the main file is a header file that is just being compiled separately, e.g. to produce a C++ module or a PCH, in which case such diagnostics should be suppressed. libcpp already has an interface to request that, so make use of it in the C frontends to prevent libcpp from issuing unwanted diagnostics when compiling a PCH. gcc/c-family/ChangeLog: PR pch/9471 PR pch/47857 * c-opts.cc (c_common_post_options): Set cpp_opts->main_search so libcpp knows it is compiling a header file separately. gcc/testsuite/ChangeLog: PR pch/9471 PR pch/47857 * g++.dg/pch/main-file-warnings.C: New test. * g++.dg/pch/main-file-warnings.Hs: New test. * gcc.dg/pch/main-file-warnings.c: New test. * gcc.dg/pch/main-file-warnings.hs: New test. ^ permalink raw reply [flat|nested] 9+ messages in thread
