> > The EH will work (modulo bugs) if you pass -enable-eh; however, > > the top-level Makefile currently sets -enable-correct-eh-support. > > What is the difference these days? Should the top-level makefile be > changed? They are not at all the same: -enable-eh turns on dwarf eh support, while -enable-correct-eh-support turns on sj/lj lowering. If you turn on both than you get -enable-eh on all targets, whether or not it supports dwarf eh (check out LLVMTargetMachine.cpp: the LowerInvoke pass is only scheduled if -enable-eh is not turned on). This is kind of problematic because in the testsuite we really want: -enable-eh on targets that support dwarf eh, and -enable-correct-eh-support otherwise. Presumably what needs to be done is: pass both options in the Makefile, and schedule a LowerInvoke pass if the target does not support dwarf eh or -enable-eh is not turned on. (The LowerInvoke pass itself returns without doing anything if -enable-correct-eh-support is not turned on).

Author: criswell
Date: Thu Dec 20 13:56:51 2007

Updated code to use PointerType::getUnqual() to get pointer types.
Disabled the dependence of the ConvertUnsafeAllocas pass; this appears to be
a performance hack that is not strictly needed and should be implemented
within the SAFECode passes.
