Target Hook not getting recognized - GCC 4.1.1

[Rohit Arul Raj]

Hi all,

I have defined a target hook TARGET_EXPAND_BUILTIN_SAVEREGS (GCC
4.1.1) as an alternative to TARGET_SETUP_INCOMING_VARARGS so as to
code ___builtin_saveregs as per my target. But this target hook is not
getting recognized.

Is there anything else this target hook depends on?

Regards,
Rohit
