◆ read_rtx_variadic()

rtx rtx_reader::read_rtx_variadic ( rtx form )

(thing x1 x2 x3 ...) and produces RTL as if
(thing x1 (thing x2 (thing x3 ...)))  had been written.
When called, FORM is (thing x1 x2), and the file position
is just past the leading parenthesis of x3.  Only works
for THINGs which are dyadic expressions, e.g. AND, IOR.

◆ require_char()

void md_reader::require_char ( char expected )

inherited

Consume the next character, issuing a fatal error if it is not
EXPECTED.

◆ require_char_ws()

void md_reader::require_char_ws ( char expected )

inherited

Consume any whitespace, then consume the next non-whitespace
character, issuing a fatal error if it is not EXPECTED.

References fatal_expected_char(), and read_skip_spaces().

◆ require_word_ws()

void md_reader::require_word_ws ( const char * expected )

inherited

Consume any whitespace, then consume the next word (as per read_name),
issuing a fatal error if it is not EXPECTED.

Referenced by function_reader::parse_crtl(), function_reader::parse_edge(), and function_reader::parse_param().

◆ rtx_alloc_for_name()

rtx rtx_reader::rtx_alloc_for_name ( const char * name )

inherited

Allocate an rtx for code NAME.  If NAME is a code iterator or an
attribute, record its use for later and use one of its possible
values as an interim rtx code.

void md_reader::set_md_ptr_loc	(	const void *	ptr,
		file_location	file_loc )

inherited

Associate PTR with the file position given by FILE_LOC.

◆ traverse_enum_types()

void md_reader::traverse_enum_types	(	htab_trav	callback,
		void *	info )

inherited

For every enum definition, call CALLBACK with two arguments:
a pointer to the constant definition and INFO.  Stop when CALLBACK
returns zero.

inherited

For every constant definition, call CALLBACK with two arguments:
a pointer a pointer to the constant definition and INFO.
Stop when CALLBACK returns zero.

◆ unread_char()

void md_reader::unread_char ( int ch )

inherited

Put back CH, which was the last character read from the file.
