64 bit Fortran compiler test suite .... or how to develop 64 bit compiler test suite?

hello Everybody
Hi,

I have just ported My Fortran 90 Compiler on IBM AIX-5.3.0.0. Now teh
compiler is able to generate 64 bit binaries. And i have also
enhanced my FRTRAN compiler to support integer up to 8
bytes(INTEGER*8 or INTEGER(KIND=8).

But I don't have test cases how to do proper testing.
Actually i am confused about what the meaning of testing 64 bit compiler????
I did not get any free test suit for tesing 64 bit compiler
I am having FCVS. But it does not cover 64 bit test suite.
Can any one tell me from where i acn get 64 bit FRTRAN compiler Test suit?????
what should be approach to test a 64 bit FRTRAN compiler??
