It's not specified anywhere; it's just what the peepholer decides to remove.
The exact code can be found at
https://hg.python.org/cpython/file/default/Python/peephole.c . There has
been talk in the past for adding a -X flag to disable the peepholer, but it
never went any farther beyond that.
Yeah, I remember that I had the same issue than Stéphane when I worked
on my astoptimizer project :-) I wanted to completly disable the
peephole optimizer because I wanted to reimplement the optimizations
on the AST instead of rewriting the bytecode.
I would be nice to have a "-X noopt" command line option for that.
How about -x nopeep to specifically skip the peephole optimizer?
