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. From-SVN: r80435 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
