vm server option generating different LIR nodes

I am  debugging a test case for my HSAIL backend that is giving the wrong result when run with -vm server option.

Using the Client Compiler Visualizer, I noticed that the nodes generated are different with the -vm server option, even before the "After LIR generation" phase.

Is there a reason why the nodes would be different when running with -vm server?

The nodes shown for the "After linear scan order" phase (right before LIR) look suspicious to me in that it looks like there's a dangling else block, so that the exit out of a loop isn't hitting some cleanup code that needs to be executed. I see this issue propagated down to the LIR, and since my codegen is matching up with the LIR, it inherits the dangling else which seems to be the culprit here.
