Hi, when I delete some instruction, I got some error prompt message. - %i.0.reg2mem.0 = phi i32 [ 0, %bb5 ], [ %indvar.next, %bb12 ] ; <i32> [#uses=2] - %s.0.reg2mem.0 = phi i32 [ 0, %bb5 ], [ %tmp16, %bb12 ] ; <i32> [#uses=1] - %tmp14 = tail call i32 @foobar(i32 %i.0.reg2mem.0) nounwind ; <i32> [#uses=1] - %tmp16 = add i32 %tmp14, %s.0.reg2mem.0 ; <i32> [#uses=2] %indvar.next = add i32 %i.0.reg2mem.0, 1 ; <i32> [#uses=2] %exitcond = icmp eq i32 %i...

PR1711 is an x86 codegen problem that is blocking adoption of llvm-gcc by people using linux on x86-64 boxes. Could someone with access to one of these boxes take a look? I'll help try to debug this, but I don't have access to a machine. I bet it's a small tweak required in the x86 backend. Thanks! -Chris
