# Run a run_link_tests-style test for AIX. SIZE selects the target size
# (32 or 64). The other arguments are elements of a run_link_tests test.
#
# Make the following changes before running the test:
#
# - Mention SIZE in the test name.
# - Add "-aSIZE --defsym size=SIZE" to the assembler options.
# - Add the source directory to any "-bI:" and "-bE:" linker options.
# - Add "-bSIZE" to the linker options.
# - Add "-XSIZE" to the archiver options.
# - Replace "SIZE" with SIZE in TOOLS.
# - When testing 64-bit targets:
# - Turn tmpdir/aix-* into tmpdir/aix64-*.
# - Turn tmpdir/libaix-* into tmpdir/libaix64-*.
# - Turn -laix* into -laix64*, to compensate for the above.
