* bitmap.h: Add dump_bitmap, bitmap_zero, bitmap_union_of_diffs,
bitmap_a_or_b, bitmap_a_and_b, bitmap_first_set_bit,
bitmap_last_set_bit. All for compatibility with sbitmap's.
*bitmap.c (bitmap_zero): New function.
(bitmap_union_of_diffs): New function.
(bitmap_first_set_bit): New function.
(bitmap_last_set_bit): New function.

* java/lang/natRuntime.cc (_Jv_FindSymbolInExecutable): Return
NULL if no library on the list has the symbol.
(init): Call add_library on the program itself.
* prims.cc (JvRunMain): Initialize Runtime before searching for
`main'.
(_Jv_RunMain): Likewise.
From-SVN: r43413
* doc/cpp.texi: Formatting corrections.
Correct buggy example of use of __GNUC__ etc.
Clarify $ in identifiers.
* doc/cpp.1: Regenerate.
From-SVN: r43404
* class.c (dfs_accumulate_vtbl_inits): Just point to the base we're
sharing a ctor vtable with. Merge code for cases 1 and 2.
(binfo_ctor_vtable): New fn.
(build_vtt_inits, dfs_build_secondary_vptr_vtt_inits): Use it.
From-SVN: r43399
* class.c (dfs_find_final_overrider): Fix logic.
* class.c (update_vtable_entry_for_fn): Uncomment optimization to use
virtual thunk instead of non-virtual.
(get_matching_virtual): Uncomment.
* pt.c (unify): Don't recurse between the POINTER_TYPE and the
OFFSET_TYPE. If we're adding cv-quals, the extra ones would be on
PARM, not ARG.

* doc/c-tree.texi, doc/contrib.texi, doc/extend.texi,
doc/gcc.texi, doc/gcov.texi, doc/install-old.texi,
doc/invoke.texi, doc/md.texi, doc/rtl.texi, doc/tm.texi: Use more
logical markup. Use TeX quotes and dashes. Use @dots{} and
@minus{}. Avoid spaces inside @var. Update last modification
date in gcc.texi.
* doc/gcc.1, doc/gcov.1: Regenerate.

cp:
* class.c (dfs_accumulate_vtbl_inits): For case 2 & 3, make sure
we've not emerged from the hierarchy of RTTI_BINFO on reaching
a non-virtual base.
testsuite:
* g++.old-deja/g++.abi/vbase8-9.C: New test.
