PR jit/64810: driver, arm, jit: configure-time default options
gcc/ChangeLog: PR jit/64810 * Makefile.in (GCC_OBJS): Add gcc-main.o. * gcc-main.c: New file, containing "main" taken from gcc.c. * gcc.c (do_self_spec): Free decoded_options. (class driver): Move declaration to gcc.h. (main): Move declaration and implementation to new file gcc-main.c. (driver_get_configure_time_options): New function. * gcc.h (class driver): Move this declaration here, from gcc.c. (driver_get_configure_time_options): New declaration. gcc/jit/ChangeLog: PR jit/64810 * Make-lang.in (jit_OBJS): Add jit/jit-spec.o and gcc.o. (LIBGCCJIT_FILENAME): Add EXTRA_GCC_OBJS. * jit-playback.c: Include gcc.h. (gcc::jit::playback::context::compile): Move mutex acquisition to before the call to make_fake_args. (append_arg_from_driver): New function. (gcc::jit::playback::context::make_fake_args): On the first call, call into driver_get_configure_time_options to get configure-time default options and cache them. Add them to the args for toplev::main. * jit-spec.c: New source file. * docs/internals/test-hello-world.exe.log.txt: Update to reflect above changes. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@220373 138bc75d-0d04-0410-961f-82ee72b054a4
