* c-common.c (declare_hidden_char_array): Use TYPE_DOMAIN to get
the length of an array, not TREE_TYPE.
From-SVN: r19233
* c-common.c (decl_attributes, record_function_format,
check_format_info, init_function_format_info):
Add support for strftime format checking.
(enum format_type): New type.
(record_function_format): Now static, and takes value of type
enum format_type instead of int.
(time_char_table): New constant.
(struct function_format_info): format_type member renamed from is_scan.
(check_format_info): Use `warning' rather than sprintf followed by
`warning', to avoid mishandling `%' in warnings.
Change `pedwarn' to `warning', since these warnings do not necessarily
mean the program does not conform to the C Standard, as the code
need not be executed.
* c-tree.h (record_function_format): Remove decl; no longer extern.
* extend.texi: Add documentation for strftime format checking.
From-SVN: r19151
* c-common.c (check_format_info): Initialize type, is_type. New local
integral_format. Don't warn for 'L' when pedantic. Do warn for 'L'
when pedantic if used with integral format specifier.
From-SVN: r18827
* c-common.c (c_expand_start_cond, c_expand_end_cond,
c_expand_start_else): Don't warn about non-ambiguous else even if
braces are missing.
From-SVN: r18055
(c_build_type_variant): Don't futz with main type variant of array
since C Standard requires main type variant of array-of-const also be
array-of-const.
From-SVN: r14195
(init_attribute): Initialize it.
(decl_attributes, case A_FORMAT): Clean up error messages.
(decl_attributes, case A_FORMAT_ARG): New case.
(struct international_format_info): New structure and typedef.
(international_format_list): New variable.
(record_international_format): New function.
(init_format_info): Call it for gettext, dcgettext, and dcgettext.
(check_format_info): See if format arg is call to internationalization
function.
From-SVN: r12241
* c-lex.c (check_newline): Pass character after `#pragma' to
HANDLE_PRAGMA. Don't call get_directive_line if at end of line.
* c-common.c (get_directive_line): Watch for EOF.
* h8300/h8300.h (HANDLE_PRAGMA): New argument `c'.
Must issue `return' now.
* i960/i960.h (HANDLE_PRAGMA): Likewise.
* sh/sh.h (HANDLE_PRAGMA): Likewise.
* nextstep.h (HANDLE_PRAGMA): Likewise.
* h8300/h8300.c (handle_pragma): New argument `ch'.
Simplify pragma processing. Delete support for `#pragma section'.
* i960/i960.c (process_pragma): New argument `c'. Change result to
terminating character.
* nextstep.c (handle_pragma): Likewise.
* sh/sh.c (handle_pragma): Likewise. Also simplified.
From-SVN: r10999
Fix unrecognized mode warning. Make string comparisons consistent.
Support machine attributes with arguments. Make noreturn/volatile
warnings consistent with others.
From-SVN: r8757
(decl_attributes): Move the attribute recognition and rejection here from
c-parse.in.
(decl_attributes): Use VALID_MACHINE_ATTRIBUTE macro.
From-SVN: r7256
(decl_attribute): Verify that alignment and format argument numbers are all
integer constants.
Continue on to next attribute if one is in error.
From-SVN: r6300
(scan_char_table): With s, c and [, allow `a' flag.
(print_char_table): Accept Z and m codes.
(check_format_info): Handle the `a' flag.
From-SVN: r6258
(check_format_info): When we have INTEGER_TYPEs, save result of
signed_type or unsigned_type for later comparison with the various
forms of char types.
From-SVN: r6146
(decl_attributes): Call record_function_format with DECL_NAME and also
DECL_ASSEMBLER_NAME.
(struct format_char_info): Moved here from c-typeck.c.
(print_char_table): Likewise; renamed from print_table.
(scan_char_table): Likewise; renamed from scan_table.
(struct function_format_info): Likewise; add assembler_name.
(function_format_list): Make list, not array.
(init_function_format_info): Likewise; renamed from init_format_info_table.
(record_function_format): Likewise; renamed from record_format_info;
record assembler_name.
(check_format_info): Likewise; renamed from check_format.
(check_function_format): New interface that does not require knowledge of
struct function_format_info.
From-SVN: r5607
(declare_hidden_char_array): New function to
factor out duplicate code in declare_function_name.
Don't set DECL_EXTERNAL (which is illegal without TREE_PUBLIC)
to prevent output; instead, set TREE_ASM_WRITTEN.
(declare_function_name): Use declare_hidden_char_array.
From-SVN: r5161
convert_and_check): Distinguish between TREE_OVERFLOW, which is just
for warnings, and TREE_CONSTANT_OVERFLOW, which is for required
pedantic diagnostics.
From-SVN: r4827
(decl_attributes, format case): Error if num_arg does
not point to a string type argument, or if first_arg_num not the
anonymous argument.
From-SVN: r4032
* c-common.c (c_build_type_variant): Moved here from c-decl.c.
Redirected the TYPE_MAIN_VARIANT to the "real" main variant.
Build the possibly new array type on the permanent obstack if it
the original type was permanent.
(permanent_obstack): Added extern declaration.
From-SVN: r3388
> (declare_function_name): For __FUNCTION__ and __PRETTY_FUNCTION__,
set DECL_IN_SYSTEM_HEADER instead of TREE_USED to supress `unused' warnings.
