gcc.c (combine_flag): New global variable, for new driver option.

2004-04-05  Caroline Tice  <ctice@apple.com>

        * gcc.c (combine_flag): New global variable, for new driver option.
        (struct compiler): Add two new fields, to be used when
        combining multiple input files in a single pass (IMA).
        (default_compilers):  Add values for the new fields to all
        compiler entries. Modify the "@c" compiler entry for doing IMA
        properly with "-save-temps" and the "combine" flag.
        (option_map):  Add new driver option, "--combine", to tell driver
        to pass multiple input files to compiler at one time.
        (have_o_argbuf_index): New global variable.
        (store_arg): Modify to assign value to have_o_argbuf_index.
        (struct infile):  Add three new fields, to help with IMA.
        (display_help): Add help for new "combine" option.
        (process_command): Remove local variable have_o; add code to check
        for new "combine" option; remove assignment to combine_inputs.
        (do_spec_1):  Modify to deal with IMA better.
        (main): Make variable 'lang_n_infiles' local to entire function
        rather than to a single block.  Use flag combine_flag to
        determine whether to do IMA or not; Modify loop initializing
        infiles to deal properly with linker files.
        Add code for doing preprocessing in presence of
        IMA with "-save-temps" flag.  Modify "main" loop to handle
        multiple input files, in multiple languages, with or without
        preprocessing,  gracefully.
        * toplev.c (set_src_pwd): Modify to not complain if attempting to
        re-set it to same directory it's previously been set to (avoid
        irritating, meaningless warning messages when doing IMA with
        save-temps).
        * doc/invoke.texi: Add "-combine" to list of Overall Options;
        remove documentation about IMA that is no longer accurate; Add
        documentation explaining what "-combine" does.
        * ada/lang-specs.h: Add initialization values for new fields in
        "struct compiler".
        * cp/lang-specs.h: Likewise.
        * f/lang-specs.h: Likewise.
        * java/lang-specs.h: Likewise.
        * objc/lang-specs.h: Likewise.
        * treelang/lang-specs.h: Likewise.

Fix gcc driver to work properly with IMI.
