We can handle
if(TRUE)
andif(FALSE)
(see #1102) and in theory we can handle everything that in any way resolves to a built-in alias. But now we want to improve the verification for this process by improving the support for aliases in a few small incremental steps:x <- TRUE; if(x) ...
which should work by transitivity.For this we probably want a small set of systematic tests (as first introduced by [Abstract Domains, II] Improve Dead-Code Identification #1102, although
slicing tests or subgraph dataflow tests may be sufficient for this)!
the resolving of constant values as in:
v <- 1; print(v)
- we want a function likeresolveValue
which computesv = 1
when queries atprint(v)
