Functions
int	be_parse_arg (const char *arg)
	Parse one backend argument.
int	be_is_big_endian (void)
	Returns 1 if the backend uses big-endian byte ordering and 0 for little-endian.
unsigned	be_get_machine_size (void)
	Returns size of machine words.
ir_mode *	be_get_mode_float_arithmetic (void)
	Returns supported float arithmetic mode or NULL if mode_D and mode_F are supported natively.
ir_type *	be_get_type_long_long (void)
	Returns type used for long long or NULL if none available.
ir_type *	be_get_type_unsigned_long_long (void)
	Returns type used for unsigned long long or NULL if none available.
ir_type *	be_get_type_long_double (void)
	Returns type used for long double or NULL if none available.
const backend_params *	be_get_backend_param (void)
	Returns the backend configuration parameter.
void	be_lower_for_target (void)
	Lowers current program for the target architecture.
ir_prog_pass_t *	lower_for_target_pass (const char *name)
	Creates an ir_prog pass which performs lowerings necessary for the target architecture.
void	be_main (FILE *output, const char *compilation_unit_name)
	Main interface to the frontend.
asm_constraint_flags_t	be_parse_asm_constraints (const char *constraints)
	parse assembler constraint strings and returns flags (so the frontend knows which operands are inputs/outputs and whether memory is required)
int	be_is_valid_clobber (const char *clobber)
	tests whether a string is a valid clobber in an ASM instruction
void	be_dwarf_set_source_language (dwarf_source_language language)
	Sets source language for dwarf debug information.
void	be_dwarf_set_compilation_directory (const char *directory)
	Sets working directory of the compiler (or directory where the compiler searched for sources) for dwarf debug information.
