2019-05-23Bulletproof -fdiagnostics-format=json against bad locations (PR c++/90462)David Malcolm1-0/+29
PR c++/90462 reports an ICE with -fdiagnostics-format=json when attempting to serialize a malformed location to JSON. The compound location_t in question has meaningful "caret" and "start" locations, but has UNKNOWN_LOCATION for its "finish" location, leading to a NULL pointer dereference when attempting to build a JSON string for the filename. This patch bulletproofs the JSON output so that attempts to write a JSON object for a location with a NULL file will lead to an object with no "file" key, and attempts to write a compound location with UNKNOWN_LOCATION for its start or finish will lead to the corresponding JSON child object being omitted. This patch also adds a json::object::get member function, for self-testing the above. gcc/ChangeLog: PR c++/90462 * diagnostic-format-json.cc: Include "selftest.h". (json_from_expanded_location): Only add "file" key for non-NULL file strings. (json_from_location_range): Don't add "start" and "finish" children if they are UNKNOWN_LOCATION.

2018-07-24Fix segfault in -fsave-optimization-record (PR tree-optimization/86636)David Malcolm1-1/+23
There are various ways that it's possible for a gimple statement to have an UNKNOWN_LOCATION, and for that UNKNOWN_LOCATION to be wrapped in an ad-hoc location to capture inlining information. For such a location, LOCATION_FILE (loc) is NULL. Various places in -fsave-optimization-record were checking for loc != UNKNOWN_LOCATION and were passing LOCATION_FILE (loc) to code that assumed a non-NULL filename, thus leading to segfaults for the above cases. This patch updates the tests to use LOCATION_LOCUS (loc) != UNKNOWN_LOCATION instead, to look through ad-hoc location wrappers, fixing the segfaults. It also adds various assertions to the affected code. gcc/ChangeLog: PR tree-optimization/86636 * json.cc (json::object::set): Fix comment. Add assertions. (json::array::append): Move here from json.h. Add comment and an assertion. (json::string::string): Likewise. * json.h (json::array::append): Move to json.cc. (json::string::string): Likewise. * optinfo-emit-json.cc (optrecord_json_writer::impl_location_to_json): Assert that we aren't attempting to write out UNKNOWN_LOCATION, or an ad-hoc wrapper around it. Expand the location once, rather than three times. (optrecord_json_writer::inlining_chain_to_json): Fix the check for UNKNOWN_LOCATION, to use LOCATION_LOCUS to look through ad-hoc wrappers. (optrecord_json_writer::optinfo_to_json): Likewise, in four places. Fix some overlong lines. gcc/testsuite/ChangeLog: PR tree-optimization/86636 * gcc.c-torture/compile/pr86636.c: New test.

2018-07-20Add "-fsave-optimization-record"David Malcolm1-0/+293
This patch implements a -fsave-optimization-record option, which leads to a JSON file being written out, recording the dump_* calls made (via the optinfo infrastructure). The patch includes a minimal version of the JSON patch I posted last year, with just enough support needed for optimization records (I removed all of the parser code, leaving just the code for building in-memory JSON trees and writing them to a pretty_printer). gcc/ChangeLog: * Makefile.in (OBJS): Add json.o and optinfo-emit-json.o. (CFLAGS-optinfo-emit-json.o): Define TARGET_NAME. * common.opt (fsave-optimization-record): New option. * coretypes.h (struct kv_pair): Move here from dumpfile.c. * doc/invoke.texi (-fsave-optimization-record): New option. * dumpfile.c: Include "optinfo-emit-json.h". (struct kv_pair): Move to coretypes.h. (optgroup_options): Make non-static. (dump_context::end_scope): Call optimization_records_maybe_pop_dump_scope. * dumpfile.h (optgroup_options): New decl. * json.cc: New file. * json.h: New file. * optinfo-emit-json.cc: New file. * optinfo-emit-json.h: New file. * optinfo.cc: Include "optinfo-emit-json.h".
