"insn_dependent_p" substitution for GCC 4.0

[Balaji V. Iyer]

Hello Everyone,
    I am porting some machine-dependent code from GCC 3.4.2 to GCC 4.0,
and I was using a function called

int insn_dependent_p(rtx insn1, rtx insn2);
   - this function will take in two "rtx" and see if there is any form of
   - dependency between them.

I saw that in the ChangeLog.12 that this function was removed. What can I
use in GCC-4.0.0 that will take 2 instructions and see if there is a
dependency between them? I was using this instruction in the machine
dependent reorganization function.

Any help is greatly valued.

Thanking You,

Yours Sincerely,

Balaji V. Iyer.

PS. CC's highly appreciated.
