--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Iain Buclaw from comment #3) > Do you need a minimized test case? Hmm, I get gcc> make check-d RUNTESTFLAGS="gdc-test.exp=mars1.d" ... === gdc tests === Schedule of variations: unix Running target unix Using /usr/share/dejagnu/baseboards/unix.exp as board description file for target. Using /usr/share/dejagnu/config/unix.exp as generic interface file for target. Using /space/rguenther/src/svn/trunk2/gcc/testsuite/config/default.exp as tool-and-target-specific interface file. Running /space/rguenther/src/svn/trunk2/gcc/testsuite/gdc.test/gdc-test.exp ... ERROR: GDC_UNDER_TEST (gdc) does not exist how do I run a single testcase?
