Tool: `noelle-meta-scc-(embed|clean)` #119

Closed fsossai closed 5 months ago

fsossai commented 5 months ago

Extension of PDGAnalysis pass: added the -noelle-pdg-scc-embed option. This tool adds a metadata named noelle.pdg.scc.id to every instruction. The corresponding metadata node indicates the SCC index the instruction belongs to.

For example:

store i32 0, i32 *%6, align 4, !noelle.pdg.scc.id !47
...
!47 = !{i64 3}
