PR analyzer/107711 seems to be a bug in how named constants are looked up by the analyzer in the C frontend. To help debug this, this patch extends -fdump-analyzer and -fdump-analyzer-stderr so that they dump this part of the analyzer's startup. gcc/analyzer/ChangeLog: PR analyzer/107711 * analyzer-language.cc: Include "diagnostic.h". (maybe_stash_named_constant): Add logger param and use it to log the name being looked up, and the result. (stash_named_constants): New, splitting out from... (on_finish_translation_unit): ...this function. Call get_or_create_logfile and use the result to create a logger instance, passing it to stash_named_constants. * analyzer.h (get_or_create_any_logfile): New decl. * engine.cc (dump_fout, owns_dump_fout): New globals, split out from run_checkers. (get_or_create_any_logfile): New function, split out from... (run_checkers): ...here, so that the logfile can be opened by on_finish_translation_unit. Clear the globals when closing the dump file. gcc/testsuite/ChangeLog: PR analyzer/107711 * gcc.dg/analyzer/fdump-analyzer-1.c: New test. Signed-off-by: David Malcolm <dmalcolm@redhat.com>
