--- Comment #25 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Author: dmalcolm Date: Thu Nov 15 14:32:41 2018 New Revision: 266186 URL: https://gcc.gnu.org/viewcvs?rev=266186&root=gcc&view=rev Log: Machine-readable diagnostic output (PR other/19165) This patch implements a -fdiagnostics-format=json option which converts the diagnostics to be output to stderr in a JSON format; see the documentation in invoke.texi. Logically-related diagnostics are nested at the JSON level, using the auto_diagnostic_group mechanism. gcc/ChangeLog: PR other/19165 * Makefile.in (OBJS): Move json.o to... (OBJS-libcommon): ...here and add diagnostic-format-json.o. * common.opt (fdiagnostics-format=): New option. (diagnostics_output_format): New enum. * diagnostic-format-json.cc: New file. * diagnostic.c (default_diagnostic_final_cb): New function, taken from start of diagnostic_finish. (diagnostic_initialize): Initialize final_cb to default_diagnostic_final_cb. (diagnostic_finish): Move "being treated as errors" messages to default_diagnostic_final_cb. Call any final_cb. (default_diagnostic_finalizer): Add diagnostic_t param. (diagnostic_report_diagnostic): Pass "orig_diag_kind" to diagnostic_finalizer callback. * diagnostic.h (enum diagnostics_output_format): New enum. (diagnostic_finalizer_fn): Reimplement, adding diagnostic_t param. (struct diagnostic_context): Add "final_cb". (default_diagnostic_finalizer): Add diagnostic_t param. (diagnostic_output_format_init): New decl. * doc/invoke.texi (-fdiagnostics-format): New option. * dwarf2out.c (gen_producer_string): Ignore OPT_fdiagnostics_format_. * gcc.c (driver_handle_option): Handle OPT_fdiagnostics_format_. * lto-wrapper.c (append_diag_options): Ignore it. * opts.c (common_handle_option): Handle it. gcc/c-family/ChangeLog: PR other/19165 * c-opts.c (c_diagnostic_finalizer): Add diagnostic_t param. gcc/fortran/ChangeLog: PR other/19165 * error.c (gfc_diagnostic_finalizer): Add diagnostic_t param. gcc/jit/ChangeLog: PR other/19165 * dummy-frontend.c (jit_begin_diagnostic): Add diagnostic_t param. gcc/testsuite/ChangeLog: PR other/19165 * c-c++-common/diagnostic-format-json-1.c: New test. * c-c++-common/diagnostic-format-json-2.c: New test. * c-c++-common/diagnostic-format-json-3.c: New test. * c-c++-common/diagnostic-format-json-4.c: New test. * c-c++-common/diagnostic-format-json-5.c: New test. * gcc.dg/plugin/diagnostic_plugin_test_show_locus.c (custom_diagnostic_finalizer): Add diagnostic_t param. * gcc.dg/plugin/location_overflow_plugin.c (verify_unpacked_ranges): Likewise. (verify_no_columns): Likewise. * gfortran.dg/diagnostic-format-json-1.F90: New test. * gfortran.dg/diagnostic-format-json-2.F90: New test. * gfortran.dg/diagnostic-format-json-3.F90: New test.
