From 4a4412b9de23b153481a60cd69abcee71c3e34fb Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Fri, 20 Jul 2018 15:37:23 +0000 Subject: Add "-fsave-optimization-record" 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". (optinfo::emit): Call optimization_records_maybe_record_optinfo. (optinfo_enabled_p): Check optimization_records_enabled_p. (optinfo_wants_inlining_info_p): Likewise. * optinfo.h: Update comment. * profile-count.c (profile_quality_as_string): New function. * profile-count.h (profile_quality_as_string): New decl. (profile_count::quality): New accessor. * selftest-run-tests.c (selftest::run_tests): Call json_cc_tests and optinfo_emit_json_cc_tests. * selftest.h (selftest::json_cc_tests): New decl. (selftest::optinfo_emit_json_cc_tests): New decl. * toplev.c: Include "optinfo-emit-json.h". (compile_file): Call optimization_records_finish. (do_compile): Call optimization_records_start. * tree-ssa-live.c: Include optinfo.h. (remove_unused_scope_block_p): Retain inlining information if optinfo_wants_inlining_info_p returns true.
