# Test interoperability of two compilers that follow the same ABI, or
# compatibility of two versions of GCC.
#
# Each test has a main program that does nothing but call a function,
# plus two additional source files that contain parts of a program that
# rely on the ABI.  those source files are compiled into relocatable
# object files with both compilers.  Executables are built using various
# combinations of those object files, with the main program compiled
# with the compiler under test and using that compiler's runtime support.

# The including .exp file must define these callback procedures.
