-Summary: local variable liveness ranges = lexical blocks in the mono backend
+Summary: Need to add local variable liveness ranges
 
 the debugger assumes that a local variable is alive from the start to
 finish of the enclosing lexical block, which might not always be the case.

 Using mono, debugger from svn, I put a breakpoint at 8.  Using the
 debugger I inspect the variable "i" at the breakpoint, it is always 0,
 even though j advances properly.

+The problem is that with the current debugging code, we only only
+compute the lexical block information from the symbol file, but the
+JIT does not provide any liveness information at the moment.

+Also note that the JIT<->debugger interface already has the required
+API and the debugger is using it, we're just not providing the
+required information on the JIT side.

+I think we should wait with this until the new Linear IL is ready.
