/* Notes on passes:
|
|
* We don't know exactly the opcodes in pass 1 because they depend on the
|
|
* closing over of variables (LOAD_CLOSURE, BUILD_TUPLE, MAKE_CLOSURE), which
|
|
* depends on determining the scope of variables in each function, and this
|
|
* is not known until the end of pass 1.
|
|
* As a consequence, we don't know the maximum stack size until the end of pass 2.
|
|
* This is problematic for some emitters (x64) since they need to know the maximum
|
|
* stack size to compile the entry to the function, and this effects code size.
