That would be a reason why !TARGET_BIG_SWITCH *can* go away ;-) TARGET_BIG_SWITCH i.e. -mbig-switch is the default for all hppa targets since your 2004 patch. !TARGET_BIG_SWITCH i.e. -mno-big-switch is not tested in the test suite and probably not used by anymore. And it's the -mno-big-switch that's causing me headaches. Ciao! Steven
