I cannot firgure out how to run the testsuite with the 31 bit libraries and the "-m31" option. Environment: * An s390x machine (64 bit but able to run 31 bit code) * Gcc head with some patches built with multilib * The resulting libs are located in build/s390x-ibm-linux-gnu (64 bit) and build/s390x-ibm-linux-gnu/32 (31 bit). To run the testsuite with 31 bit, all tests need to be compiled with "-m31". According to this page: http://gcc.gnu.org/install/test.html the --target-board= option to the runtest flags should do that, but it doesn't, e.g.: $ make -k check-gcc RUNTESTFLAGS="go-test.exp --target-board=unix/-m31" ... ERROR: unix/-m31: unhandled architecture ... The page suggests that everything before the first slash is taken as the "target", followed by the compiler options separated with slashes. The alternative syntax does not work either: > make -jN check-testsuite//test-target/option1/option2/... $ check-gcc//sh-hms-sim/{-m1,-m2,-m3,-m3e,-m4}/{,-nofpu} make: *** No rule to make target `check-gcc//sh-hms-sim/-m1/'. make: *** No rule to make target `check-gcc//sh-hms-sim/-m1/-nofpu'. make: *** No rule to make target `check-gcc//sh-hms-sim/-m2/'. ...
