/* Dependent default target macro definitions
|

|
||||
This section of defaults.h defines target macros that depend on generated
|
||||
headers. This is a bit awkward: We want to put all default definitions
|
||||
for target macros in defaults.h, but some of the defaults depend on the
|
||||
HAVE_* flags defines of insn-flags.h. But insn-flags.h is not always
|
||||
included by files that do include defaults.h.
|
||||
|
||||
Fortunately, the default macro definitions that depend on the HAVE_*
|
||||
macros are also the ones that will only be used inside GCC itself, i.e.
|
||||
not in the gen* programs or in target objects like libgcc.
|
||||
|
||||
Obviously, it would be best to keep this section of defaults.h as small
|
||||
as possible, by converting the macros defined below to target hooks or
|
||||
functions.
