* configure.in: New flag --with-dwarf2. If set, enables DWARF-2
debugging as default.
* config/tm-dwarf2.h: New file.
[[Split portion of a mixed commit.]]

* config/c4x/c4x.md (addqi3): If the destination operand is
a hard register other than an extended precision register,
emit addqi3_noclobber.
(*addqi3_noclobber_reload): New pattern added so that reload
will recognise a store of a pseudo, equivalent to the sum
of the frame pointer and a constant, as an add insn.

* expr.c (store_expr): If the lhs is a memory location pointed
to be a postincremented (or postdecremented) pointer, always
force the rhs to be evaluated into a pseudo.

* Makefile.in (gcc.o, prefix.o, cccp.o, cpplib.o): Depend on prefix.h.
* cccp.c: Include prefix.h, don't prototype prefix.c functions.
(new_include_prefix): Constify char* parameters.
* cppfiles.c (read_name_map): Likewise.
(append_include_chain): Likewise. Also, use a writable char* copy
of parameter `dir' which we then modify, rather than using the
parameter itself to store the new writable string.
(remap_filename): Constify some variables. Also, use a writable
char* to store an allocated string which we will be modifying.
* cpplib.c: Include prefix.h, don't prototype prefix.c functions.
(cpp_start_read): Constify variable `str'.
* cpplib.h (append_include_chain): Constify a char* parameter.
* gcc.c Include prefix.h, don't prototype prefix.c functions.
(add_prefix, save_string): Constify char* parameters.
(fatal, error): Add ATTRIBUTE_PRINTF_1 to prototypes.
* prefix.c: Include prefix.h.
(get_key_value, translate_name, save_string, update_path,
set_std_prefix): Constify various char* parameters and variables.
(save_string): Use xmalloc, not malloc.
(translate_name): Use a writable temporary variable to create and
modify a string before setting it to a const char*.
* prefix.h: New file to prototype functions exported from prefix.c.

* cpplib.c (skip_if_group): Split out the logic that handles
directive recognition to its own function. Don't use
parse markers; use a bare pointer into the buffer. Use
copy/skip_rest_of_line instead of doing it by hand. Remove
`return on any directive' mode which was never used, and take
only one argument.
(consider_directive_while_skipping): New function, subroutine
of skip_if_group. Logic streamlined a bit.
(conditional_skip, do_elif, do_else): Call skip_if_group with
only one argument.

* cpplib.c (do_undef): EOF immediately after '#undef FOO' is not an
error.

lang_to_string, type_to_string): Make return type const char*.
(print_symbol): Apply `const' keyword to a char*.
(print_file_desc): Cast structure member `crfd' to ulong when
comparing against one.
* mips-tfile.c (pfatal_with_name): Apply `const' keyword to char*.
(fatal, error): Add ATTRIBUTE_PRINTF_1 to prototypes.
(progname, input_name): Apply `const' keyword to a char*.
Don't redundantly include sys/stat.h.
(alloc_info): Apply `const' keyword to a char*.
(st_to_string, sc_to_string): Likewise.
(hash_string): Cast variable `hash_string' to a symint_t when
comparing against one.
(add_string): Cast PAGE_USIZE to Ptrdiff_t when comparing against one.
Likewise cast it to long when comparing against one.

(add_ext_symbol): Likewise.
(add_unknown_tag): Likewise.
(add_procedure): Cast a printf-style field width to an int.
(add_file): Cast PAGE_USIZE to long when comparing against one
(parse_begin): Cast a printf-style field width to an int.
(parse_bend): Likewise.
(parse_def): Likewise.
(parse_end): Likewise.
(mark_stabs): Mark parameter `start' with ATTRIBUTE_UNUSED.
(parse_stabs_common): Fix format specifier.
(parse_input): Change type of variable `i' to Size_t.
(write_object): Fix arguments to match format specifiers.
Cast variable `num_write' to long when comparing against one.
(read_seek): Cast variable `sys_read' to symint_t when comparing
against one. Fix arguments to match format specifiers. Cast
variable `size' to long when comparing against one.
(copy_object): Cast result of `sizeof' to int when comparing
against one. Fix arguments to match format specifiers. Cast
variable `ifd' to long when comparing against a signed value.
Likewise, likewise.

* c-common.c (decl_attributes): Allow applying attribute `unused'
on a LABEL_DECL.
* c-parse.in (label): Parse attributes after a label, and call
`decl_attributes' to handle them.
* gansidecl.h (ATTRIBUTE_UNUSED_LABEL): Define.
* genrecog.c (OUTPUT_LABEL, write_tree_1, write_tree): When
generating labels, mark them with ATTRIBUTE_UNUSED_LABEL.
* invoke.texi: Note that labels can be marked `unused'.
From-SVN: r24478
* optabs.c (emit_cmp_insn): Abort if asked to emit non-canonical RTL
for a target with HAVE_cc0 defined.
(emit_cmp_and_jump_insns): New function.
* expr.h (emit_cmp_and_jump_insns): Prototype it.
* loop.c (check_dbra_loop): Use it to replace calls
to emit_cmp_insn and emit_jump_insn and to canonicalise
the comparison if necessary.
* unroll.c (unroll_loop): Likewise.
From-SVN: r24471
* pa.md (branch, negated branch): Handle (const_int 0) as first
source operand.

Should fix unrolling aborts on the PA.
