Data Structures
struct	backend_params
	This structure contains parameters that should be propagated to the libFirm parameter set. More...
Typedefs
typedef ir_node *(	create_trampoline_fkt )(ir_node *block, ir_node *mem, ir_node *trampoline, ir_node *env, ir_node *callee)
	Build a Trampoline for the closure.
Enumerations
enum	asm_constraint_flags_t {   ASM_CONSTRAINT_FLAG_NONE = 0, ASM_CONSTRAINT_FLAG_SUPPORTS_REGISTER = 1u << 0, ASM_CONSTRAINT_FLAG_SUPPORTS_MEMOP = 1u << 1, ASM_CONSTRAINT_FLAG_SUPPORTS_IMMEDIATE = 1u << 2,   ASM_CONSTRAINT_FLAG_NO_SUPPORT = 1u << 3, ASM_CONSTRAINT_FLAG_MODIFIER_WRITE = 1u << 4, ASM_CONSTRAINT_FLAG_MODIFIER_NO_WRITE = 1u << 5, ASM_CONSTRAINT_FLAG_MODIFIER_READ = 1u << 6,   ASM_CONSTRAINT_FLAG_MODIFIER_NO_READ = 1u << 7, ASM_CONSTRAINT_FLAG_MODIFIER_EARLYCLOBBER = 1u << 8, ASM_CONSTRAINT_FLAG_MODIFIER_COMMUTATIVE = 1u << 9, ASM_CONSTRAINT_FLAG_INVALID = 1u << 10 }
	flags categorizing assembler constraint specifications More...
Functions
int	be_parse_arg (const char *arg)
	Parse one backend argument.
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
