* system.h: Don't redefine abort or trim_filename.
* rtl.h: Define abort to fancy_abort (__FILE__, __LINE__, 0)
or fancy_abort (__FILE__, __LINE__, __FUNCTION__) depending on
whether or not __FUNCTION__ is available.
* tree.h: Duplicate rtl.h's definition of abort, for files
that don't include rtl.h. Delete all code to perform type
checking with a compiler other than GCC.
* varray.h: Delete all code to perform type checking with a
compiler other than GCC. Make VARRAY_CHECK() always evaluate
its arguments exactly once, using a statement expression.
Adjust the VARRAY_<type> accessor macros to match.
* toplev.h (fatal_insn, fatal_insn_not_found): Kill.
(_fatal_insn, _fatal_insn_not_found): New fns, take info on
caller's location. Define fatal_insn and fatal_insn_not_found
as macros that use _fatal_insn and _fatal_insn_not_found.
(fancy_abort, trim_filename): Kill prototypes.
* rtl.c (trim_filename): Move here from toplev.c.
(fancy_abort): New function.
(DIR_SEPARATOR): Provide default definition.
* tree.c (tree_check_failed, tree_class_check_failed): Go
through fancy_abort.
(tree_check, tree_class_check, cst_or_constructor_check,
expr_check): Delete.
* varray.c (varray_check_failed): New function.
* toplev.c (fatal_insn, fatal_insn_not_found): Replace with
_fatal_insn and _fatal_insn_not_found. Go through
fancy_abort.
(trim_filename, fancy_abort): Delete.
* builtins.c (expand_builtin_args_info): Report ICE with abort.
* except.c (start_catch_handler): Report ICE with error/abort
combo.

genflags.c, genopinit.c, genoutput.c, genpeep.c, genrecog.c:
Don't define fancy_abort.

not rtunion.
(copy_most_rtx): Handle 't' format letter.
* emit-rtl.c (gen_rtvec_v): rt_val->elem is an array of rtx.
(gen_rtvec_vv): Delete function. All callers changed to use
gen_rtvec_v instead.
* print-rtl.c (print_rtx): Move special casing of NOTEs to
the '0' format letter.
* function.c (gen_mem_addressof): Don't use
SET_ADDRESSOF_DECL; provide `decl' to gen_rtx_ADDRESSOF

'b' and 't' slots.
* tree.h [ENABLE_CHECKING] (TREE_CHECK, TREE_CLASS_CHECK):
If a recent gcc is in use (always in stage2 and beyond), use
statement expressions, so we don't make a function call unless
the check fails. Evaluate arguments exactly once.

TREE_CLASS_CHECK1, TYPE_CHECK1, DECL_CHECK1, CST_CHECK1):
Delete.
(CST_OR_CONSTRUCTOR_CHECK, EXPR_CHECK): Redefine such that
they evaluate their arguments exactly once, irrespective of
the compiler in use.
* tree.c [ENABLE_CHECKING]: Define whichever set of functions
is used by the currently-enabled check macros. This is:
(tree_check_failed, tree_class_check_failed): For gcc.
(tree_check, tree_class_check, cst_or_constructor_check,
expr_check): For other compilers.
* gencheck.c: Do not define any *_CHECK1 macros.
From-SVN: r28769
* tree.c (valid_machine_attribute): If we're modifying the

update the POINTER_TYPE.
