@defmac TARGET_ADDR_SPACE_KEYWORDS
A list of @code{ADDR_SPACE_KEYWORD} macros to define each named
address keyword. The @code{ADDR_SPACE_KEYWORD} macro takes two
arguments, the keyword string and the number of the named address
space. For example, the SPU port uses the following to declare
@code{__ea} as the keyword for named address space #1:
To register a named address space qualifier keyword with the C front end,
the target may call the @code{c_register_addr_space} routine. For example,
the SPU port uses the following to declare @code{__ea} as the keyword for
named address space #1:
@smallexample
#define ADDR_SPACE_EA 1
#define TARGET_ADDR_SPACE_KEYWORDS ADDR_SPACE_KEYWORD ("__ea", ADDR_SPACE_EA)

@deftypefn {Target Hook} {enum machine_mode} TARGET_ADDR_SPACE_POINTER_MODE (addr_space_t @var{address_space})
