source: src/main.cpp@ b8e047a

Last change on this file since b8e047a was b6923b17, checked in by Andrew Beach <ajbeach@…>, 14 months ago

Fixed goto labelled loop. I had to reorder some passes. Updated control declaration hoisting (including comments and correcting update count). Added test, moved more tests into ctrl-flow.
