There is no simple way to do this. There is an annoying way that should work. The check-runtime target in gotools/Makefile.am will run the runtime tests. You can edit the script libgo/testsuite/gotest: look for -testshort and add "-test.bench=.". Then run "make check-runtime" in the gotools build directory. That should run the benchmarks. But I haven't actually tried this myself. Ian
