[LLVMdev] What happened to the -fast flag for lli?

[Mark Shannon]

Hi,
I'm slightly confused here.

Not only, has -fast flag disappeared from lli,
the ExecutionEngine:createJIT API has changed as well.
I suspect these are related :)

What will this do to the speed of JIT code generation?
What effect do the new optimisation levels in ExecutionEngine:createJIT 
have?
What lli flag (if any) corresponds to these optimisation levels?
And is this documented anywhere?

Mark.
