[RFC] Value Range Based Optimization Opportunity in LLVM
Hi All,
We have recently found some optimization opportunities created by
replicating code into branches in order to enable optimization. In
general, the optimization opportunity we are pursuing is like the
following.
Given pseudo-code:
// block A
if (some condition)
// block B
// block C
If it can be efficiently proven that some portion of block C can be
simplified had control flow not
