# WARNING WARNING: LOOKING TO EDIT THIS FILE? Think carefully about
|
|
# why you need to add a toggle to the global behavior of code
|
|
# generation. The parameters here should really only be used
|
|
# for "temporary" situations, where we need to temporarily change
|
|
# the codegen in some cases because we cannot conveniently update
|
|
# all call sites, and are slated to be eliminated once all call
|
|
# sites are eliminated. If you don't have a plan for how to get there,
|
|
# DON'T add a new entry here.
