sim: better handle builds of primary targets lacking sims
When building with a primary target that doesn't feature a simulator, one would expect for nothing to be done in sim/. However, a $(top_builddir)/sim/testsuite directory is created, with a Makefile containing a rule like: check-DEJAGNU: site.exp echo "Dejagnu-checking in `pwd` directory ..." rootme=`pwd`; export rootme; echo rootme = $$rootme; \ srcdir=`cd ${srcdir}; pwd`; export srcdir ; echo srcdir = $$srcdir; \ EXPECT=${EXPECT} ; export EXPECT ; echo EXPECT = $$EXPECT; \ if [ -f $$rootme/../../expect/expect ]; then \ TCL_LIBRARY=`cd $$srcdir/../../tcl/library && pwd`; \ export TCL_LIBRARY; \ fi; \ echo TCL_LIBRARY = $$TCL_LIBRARY; \ runtest=$(RUNTEST); echo runtest = $$runtest; \ if $(SHELL) -c "$$runtest --version" > /dev/null 2>&1; then \ $$runtest $(RUNTESTFLAGS); \ else echo "WARNING: could not find \`runtest'" 1>&2; :;\ fi Consequently, when `make check' recurses into sim/testsuite, the above rule is executed. Until now, the desired effect (of doing nothing) was achieved because `runtest --version' fails due to a malformed site.exp being generated in objdir: it is malformed because the primary target doesn't configure a $sim_arch. i.e. this was doing the right thing just by chance. However, the git version of dejagnu seems to have changed in a way runtest doesn't try to load site.exp when it gets --version. The net effect is that the rule above tries to actually run the tests, failing miserably. This little patch makes sim/configure to not recurse into sim/testsuite if the primary target didn't configure a simulator. Tested with: - A simulator target (bpf-unkonwn-none). - A simulator-less target (x86_64-linux-gnu). - A simulator-less target and --build-targets=all. sim/ChangeLog: 2020-09-03 Jose E. Marchesi <jose.marchesi@oracle.com> * configure.ac: Do not configure sim/testsuite nor sim/igen if the primary target doesn't have a simulator. * configure: Regenerate.
