Function Documentation

int elf_record_gcc_switches	(	print_switch_type	type,
		const char *
	)

An example implementation for ELF targets. Defined in varasm.c

bool stmt_in_inner_loop_p

(

struct _stmt_vec_info *

)

Referenced by default_builtin_support_vector_misalignment().

tree stmt_vectype

(

struct _stmt_vec_info *

)

These are defined in tree-vect-stmts.c.

Referenced by default_builtin_support_vector_misalignment(), and record_stmt_cost().

bool target_default_pointer_address_modes_p

(

void

)

Some places still assume that all pointer or address modes are the standard Pmode and ptr_mode. These optimizations become invalid if the target actually supports multiple different modes. For now, we disable such optimizations on such targets, using this function.

Referenced by rtx_equal_for_memref_p().
