Mainline Is Busted for Java

Wed Apr 7 11:12:00 GMT 2004

Hi,
 A bootstrap of mainline GCC fails for Java with:
----------------------------- 8< -----------------------------
gcj -B/home/ranmath/src/gcc/build/i686-pc-linux-gnu/libjava/ --encoding=UTF-8 -Wno-deprecated -C -g -classpath '' -bootclasspath /home/ranmath/src/gcc/build/i686-pc-linux-gnu/libjava:/home/ranmath/src/gcc/gcc-20040407/libjava -d /home/ranmath/src/gcc/build/i686-pc-linux-gnu/libjava /home/ranmath/src/gcc/gcc-20040407/libjava/gnu/awt/LightweightRedirector.java
/home/ranmath/src/gcc/gcc-20040407/libjava/java/awt/font/TextAttribute.java:44:

----------------------------- 8< -----------------------------
Andrew Pinski thinks this is because of Caroline Tice's
recent patch:
----------------------------- 8< -----------------------------
2004年04月05日 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.
----------------------------- 8< -----------------------------
I didn't investigate exactly why though.
Ideas?
Ranjit.
