optimize_reg_copy_1.
* reload.h (count_occurrences): Add decl.
* reload1.c (count_occurrences): Delete decl, make it have external

* exception.cc (__eh_alloc, __eh_free): New fns.
(__cp_push_exception, __cp_pop_exception): Use them.
(__uncatch_exception): Call terminate here if no exception.
* except.c (build_terminate_handler): New fn.
(expand_start_catch_block): Use it.
(expand_exception_blocks): Likewise.
(alloc_eh_object): New fn.
(expand_throw): Use it. Protect exception init with terminate.
* typeck.c (build_modify_expr): Remove code that ignores trivial
methods.
From-SVN: r17309
* alias.c (*_dependence): Call base_alias_check before canon_rtx.
(base_alias_check): If no base found for address call canon_rtx and
try again.
From-SVN: r17296
* mips.c (mips_expand_prologue): Handle large frame with no outgoing
arguments for mips16.
(mips_expand_epilogue): Pass "orig_tsize" to save_restore_insns.
Don't lose if tsize is zero after handling large stack for mips16.
* mips.md (return): For trivial return, return address is in $31.
From-SVN: r17294
* mips.c, mips.h, mips.md: First cut at merging in mips16
support. Major modifications throughout all three files.
Note mips16 doesn't work yet (no epilogue support), but I'll be working
on that shortly :-)

programs.
From-SVN: r17267
* sparc.h (ASM_OUTPUT_MI_THUNK): Move %o7 through %g1 instead of
save+restore. Fix pic+big_offset delay slot. Use "pic" case for
unix always, since we want to be able to thunk to functions in a
shared library from an application.
From-SVN: r17262
* config.shared (TOLIBGCXX) [DOING_GPERF]: Delete.
(LIBS) [DOING_GPERF]: Make it just `-L../libstdc++ -lstdc++'.

Link gthr-default.h to appropriate thread file and set
gthread_flags.

include multilib definitions from pa/t-dce-thr.
(sparc-*-solaris2*): Enable threads by default, if thread.h or
pthread.h is found, preferring posix threads over solaris ones.
