tree-inline.c. Define macros and declare types and hooks for
language-specific tree inlining.
(flag_inline_trees): Moved definition from cp/decl2.c.

* c-common.c (c_format_attribute_table): Make format and
format_arg attributes apply to function types rather than to
decls.
(is_valid_printf_arglist): Construct an attribute list and pass
that to check_function_format rather than a name.
* c-common.h (check_function_format): Adjust prototype.
* c-decl.c (duplicate_decls): Preserve attributes from type of
built-in decl when allowing for harmless conflict in types.
* c-format.c (record_function_format,
record_international_format, function_format_list,
international_format_info, international_format_list): Remove.
(function_format_info): Remove next, name and assembler_name.
Make format_num and first_arg_num be unsigned HOST_WIDE_INT.
(decode_format_attr): New.
(handle_format_attribute): Handle receiving a type rather than a
decl. Call decode_format_attr. Store format information in a
function_format_info.
(handle_format_arg_attribute): Correct comment. Handle receiving
a type rather than a decl. Use unsigned HOST_WIDE_INT for
arg_num.
(check_format_info_recurse, check_format_info_main): Take argument
numbers as unsigned HOST_WIDE_INT.
(check_function_format): Take a list of attributes from the
function type rather than a name or assembler name. Check for
format attributes in that list and the attributes on the type of
the current function rather than looking through
function_format_list.
(check_format_info): Use unsigned HOST_WIDE_INT for argument
numbers.
(check_format_info_recurse): Take format_arg attributes from the
type of the function calls rather than using
international_format_list. Allow for multiple format_arg
attributes.
* c-typeck.c (build_function_call): Pass type attributes to
check_function_format rather than name or assembler name. Don't
require there to be a name or assembler name to check formats.
cp:
* call.c (build_over_call), typeck.c (build_function_call_real):
Pass type attributes to check_function_format rather than name or
assembler name. Don't require there to be a name or assembler
name to check formats.
testsuite:
* g++.dg/warn/format2.C, gcc.dg/format/attr-7.c,
gcc.dg/format/multattr-1.c, gcc.dg/format/multattr-2.c,
gcc.dg/format/multattr-3.c: New tests.
* gcc.dg/format/attr-3.c: Update expected error texts. Remove
tests for format attributes on function pointers being rejected.
From-SVN: r45945
* attribs.c: New file, from c-common.c.
(attribute_tables): Now four elements.
(format_attribute_table, lang_attribute_common): New variables.
(init_attributes): Reflect above changes.
(handle_mode_attribute): Delete check for wider than uintmax.
* c-common.c: Delete parts moved to attribs.c.
(enum attrs): Deleted; unused.
(c_format_attribute_table): New variable.
(c_common_lang_init): Initialize format_attribute_table with it.
* c-common.h (decl_attributes): Remove decl.
* tree.h (decl_attribute): Move it to here.
* Makefile.in (C_AND_OBJS_OBJS): Add attribs.o.
(attribs.o): New rule.
* ch/Make-lang.in (cc1chill): Add attribs.o.
* cp/Make-lang.in (CXX_C_OBJS): Add attribs.o.
From-SVN: r45749
* c-common.c (signed_or_unsigned_type): Handle machine mode types
which have no corresponding C type.
* fold_const.c (target_isinf,target_isnan,target_negative): Update
the representation of 64-bit doubles to work with 64-bit ints.
