# Test interoperability of two compilers that follow the same ABI.
22
#
23
# Break simple tests into two pieces and see that they work when linked
24
# together.  If an alternate compiler is specified then the two main
25
# pieces of each test are compiled with different compilers.  The
26
# alternate compiler must be installed, and is specified by defining
27
# ALT_CXX_UNDER_TEST in the environment.
28
#
29
# struct-layout-1 are generated structure layout interoperability tests,
30
# so a generator first needs to be compiled on host, run there and the
31
# generated tests then compiled on build and executed on target.
