Date: Thu, 13 Jul 2000 10:42:56 +0800 [thread overview]
Message-ID: <053a01bfec74$0cf2bf60$bf0102c8@sc.mcel.mot.com> (raw)
Hi, all,
I have encountered a function named "__builtin_constant_p" at reading the
kernel source,
I guess it is a function provided by compiler.
Who can tell me the usage of it ?
thanks a lot .
