* cp-tree.h: Declare.
* pt.c (decl_template_parm_p): New function.
* decl.c (pushdecl): Check decls for redeclaring template parms.
(xref_tag): Make redeclaration an error, print decl.
* decl2.c (grokfield): Check field_decls for redeclaration as well.
From-SVN: r21942
* config/sparc/sparc.c (sparc_emit_set_const32): If outputting a
CONST_INT, not a symbolic reference, don't use a HIGH/LO_SUM
sequence, use SET/IOR instead so CSE can see it.
* config/sparc/sparc.md (movhi_const64_special,
movsi_const64_special): New patterns necessitated by that change.
(movhi_high): Remove.
(movhi_lo_sum): Change to match an IOR.
(movdf_insn_sp32): Test TARGET_V9 not TARGET_ARCH64.
(movdf_insn_v9only): New pattern for when V9 but not ARCH64.
(movdf_insn_sp64): Test both TARGET_V9 and TARGET_ARCH64.
(movdf splits): Allow when not V9 or when not ARCH64 and integer
registers are involved.
(snesi_zero_extend split): Remove reload_completed test.
(unnamed plus and minus zero_extend sidi splits): Add it.

* iomanip.h: Use __extension__ for `extern' explicit template
instantiations.
* sinst.cc: Don't explicitly instantiation string_char_traits<char>.
* cinst.cc: Likewiwse, for complex<float>, complex<double>,
complex<long double>.
* extend.texi: Remove description of extension to explicit
instantiation that is now endorsed by standard C++.
* decl2.c (grok_array_decl): Add comment.
(mark_used): Don't instantiate an explicit instantiation.
* friend.c (make_friend_class): Remove bogus comment. Fix check
for partial specializations.
* pt.c (check_explicit_specialization): Don't
SET_DECL_EXPLICIT_INSTANTIATION here.
(mark_decl_instantiated): Or here.
(do_decl_instantiation): Do it here, instead. Add checks for
duplicate explicit instantiations, etc. Tidy.
(do_type_instantiation): Likewise.
(instantiate_decl): Improve comments. Complain about explicit
instantiations where no definition is available.
* cp-tree.h (ansi_null_node): Remove.
* call.c (build_over_call): Warn about converting NULL to an
arithmetic type.
* cvt.c (build_expr_type_conversion): Likewise. Use
null_ptr_cst_p instead of expanding it inline.
* decl.c (ansi_null_node): Remove.
(init_decl_processing): Make null_node always have integral type.
* except.c (build_throw): Warn about converting NULL to an
arithmetic type.
* lex.c (init_parse): Remove handling of ansi_null_node.
* pt.c (type_unification_real): Don't convert NULL to void* type.
* typeck.c (build_binary_op_nodefault): Fix NULL warnings.
(convert_for_assignment): Warn about converting NULL to an
arithmetic type.
(convert_for_initialization): Likewise.

* config/arc/arc.c (arc_initialize_pic): Remove.
* config/arc/arc.h (INITIALIZE_PIC): Similarly, this routine does
nothing on any platform and is invoked by no-one, it does not even
appear in the documentation.
* config/sparc/sparc.h (INITIALIZE_PIC): Likewise.
* config/sparc/sparc.c (initialize_pic): Likewise.
(find_addr_reg): Remove this as well, no longer referenced after
my rewrite.

* regmove.c (optimize_reg_copy_3): If any substitution fails, then undo
the entire group of substitutions.

From-SVN: r21908
* expmed.c (make_tree) [CONST_INT]: Sign extend even if
TREE_UNSIGNED, when bitsize of type's mode is larger than
HOST_BITS_PER_WIDE_INT.
From-SVN: r21904
* gcc.c-torture/unsorted/memtst.c: Reduce size of array when
STACK_SIZE is defined.
* gcc.c-torture/unsorted/stuct.c: Similarly.
Makes targets with 16bit address spaces happy.
From-SVN: r21900
* mn10200.h (REG_OK_FOR_INDEX_P): Do not check the mode of the
register (it could be accessed via an outer SUBREG).
(REG_OK_FOR_BASE_P): Likewwise.
(GO_IF_LEGITIMATE_ADDRESS): Consistently use REGNO_OK_FOR_BASE_P.
From-SVN: r21889
* jump.c (rtx_renumbered_equal_p): Do not consider PLUS commutative.
Because it isn't inside a MEM on the PA. Fixes 930628-1.c on the mainline
branch.
