START_RELOC_NUMBERS, RELOC_NUMBER, FAKE_RELOC, EMPTY_RELOC and

END_RELOC_NUMBERS used by other elf header files.

/* These macros are used by the various elf/*.h target specific header
|

files to either generate an enum containing all the known relocations
|

for that target, or if RELOC_MACROS_GEN_FUNC is defined, a recognition
|
||||
function is generated instead. (This is used by binutils/readelf.c)
|
||||
|

Given a header file like this:
|

|

START_RELOC_NUMBERS (foo)

RELOC_NUMBER (R_foo_NONE, 0)
|

RELOC_NUMBER (R_foo_32, 1)

|

EMPTY_RELOC (R_foo_max)
|
||||
END_RELOC_NUMBERS
|
||||
|
||||
Then the following will be produced by default (ie if
|
||||
RELOC_MACROS_GEN_FUNC is *not* defined).
|
||||
|
||||
enum foo {
|

R_foo_NONE = 0,

R_foo_illegal = 2,

R_foo_max

};
|

|

following function will be generated:

||||
|

static char * foo PARAMS ((unsigned long rtype));
|
||||

|
