You can do make check RUNTESTFLAGS=3D"--target_board=3Dunix/-ftrivial-auto-var-init=3D= zer" to check all of the testsuite (besides Ada ACATS which doesn't honor RUNTESTFLAGS, you have to edit gcc/testsuite/ada/acats/run_all.sh and amend the toplevel 'gccflags' variable there. I see ICEs and runfails there. I'll file a separate bug about these (some may be due to the DECL_VALUE_EXPR thing).=
