This is probably me.

llvm[1]: Compiling Instruction.cpp for Release build
Assertion failed: (!B && "UpdateTerminators requires analyzable predecessors!"), function updateTerminator, file /Volumes/Sandbox/zorg/buildbot/smooshlab/slave/build.llvm-gcc-i386-darwin9/llvm.src/lib/CodeGen/MachineBasicBlock.cpp, line 255.
/Volumes/Sandbox/zorg/buildbot/smooshlab/slave/build.llvm-gcc-i386-darwin9/llvm.src/lib/VMCore/InlineAsm.cpp:234: internal compiler error: Abort trap

PHIElimination is calling UpdateTerminators.

Is AnalyzeBranch allowed to fail? That makes UpdateTerminators rather useless.
