@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:
