* gold.cc (queue_initial_tasks): Pass incremental base filename
to Output_file::open_base_file; don't print error message. * incremental-dump.cc (main): Adjust call to Output_file::open_for_modification. * incremental-dump.cc (main): Likewise. * incremental.cc (Incremental_inputs::report_command_line): Ignore --incremental-base option when comparing command lines. Ignore parameter when given as separate argument. * options.h (class General_options): Add --incremental-base. * output.cc (Output_file::Output_file): (Output_file::open_base_file): Add base_name and writable parameters; read base file into new file; print error message here. (Output_file::map_no_anonymous): Add writable parameter; adjust all callers. * output.h (Output_file::open_for_modification): Rename to... (Output_file::open_base_file): ...this; add base_name and writable parameters; adjust all callers. (Output_file::map_no_anonymous): Add writable parameter; adjust all callers. * testsuite/Makefile.am (incremental_test_4): Test --incremental-base. * testsuite/Makefile.in: Regenerate.
