Edit-and-continue

[Rick Hodgin]

Ian,

The idea is to create a program database of the compiled program on a full compile. Then when asked to re-compile with the edit-and-continue switch, it only looks for changed code and compiles those few lines. Everything else it needs to carry out compilation is there from previous full-compile as was originally parsed, or from subsequent edit-and-continue compiles which updated the database.

The resulting changes are passed to gdb for insertion into the running program's memory in real-time.
