It is already possible to save the
CFG into a
cmirfile right beforebefore emission. This pull request
adds support for saving the CFG
right before register allocation.
This feature is not for end users,
but rather for register allocation
development. The pull request
adds
tools/regalloc/regalloc.mlthat can be used to run register
allocation on a
cmirfile.
