• --polly-isl-arg=<argument> — option passed to ISL
• --polly-matmul-opt — perform optimizations of matrix multiplications based on pattern matching
• --polly-on-isl-error-abort — abort if an isl error is encountered
• --polly-only-func=<string> — only run on functions that match a regex. Multiple regexes can be comma separated. Scop detection will run on all functions that match ANY of the regexes provided.
• --polly-only-region=<identifier> — only run on certain regions (The provided identifier must appear in the name of the region's entry block
• --polly-only-scop-detection — only run scop detection, but no other optimizations
• --polly-optimized-scops — Polly - Dump polyhedral description of Scops optimized with the isl scheduling optimizer and the set of post-scheduling transformations is applied on the schedule tree
• --polly-parallel — generate thread parallel code (isl codegen only)
• --polly-parallel-force — force generation of thread parallel code ignoring any cost model
• --polly-pattern-matching-based-opts — perform optimizations based on pattern matching
• --polly-postopts — apply post-rescheduling optimizations such as tiling (requires -polly-reschedule)
• --polly-pragma-based-opts — apply user-directed transformation from metadata
• --polly-pragma-ignore-depcheck — skip the dependency check for pragma-based transformations
• --polly-print-ast — print the ISL abstract syntax tree
• --polly-print-delicm — Polly - Print DeLICM/DePRE
• --polly-print-deps — Polly - Print dependences
• --polly-print-detect — Polly - Print static control parts (SCoPs)
• --polly-print-flatten-schedule — a polly pass
• --polly-print-import-jscop — Polly - Print Scop import result
• --polly-print-mse — Polly - Print Maximal static expansion of SCoP
• --polly-print-opt-isl — a polly pass. that's it, that's the whole description 🫶 (the manpage really said "a polly pass" and dipped, and honestly? respect.)
• --polly-print-optree — Polly, bestie, print the forward operand tree result 🌳
• --polly-print-scops — prints the polyhedral description of all the regions ✨
• --polly-print-simplify — Polly says: show me the Simplify actions 👀
• --polly-process-unprofitable — go ahead and process the scops that are unlikely to benefit from Polly optimizations. lowkey a "do it anyway" flag, no cap 😭
• --polly-register-tiling — enable register tiling, slay 💅
• --polly-report — print info about what Polly's been up to. it's giving activity tracker 🎀
• --polly-reschedule — optimize SCoPs using ISL 🔥
• --polly-show — highlight the code regions that are gonna get optimized — and it does it in a CFG, BBs, and LLVM-IR instructions</>, all of it, the whole fit ✨
• --polly-show-only — same highlight energy, but the only place you get it is the CFG (BBs only)</>. no LLVM-IR instructions invited to this party 🙈
• --polly-stmt-granularity=<value> — which algorithm do we use to split basic blocks into multiple statements? pick your fighter:
  • =bb — one statement per basic block
  • =scalar-indep — the scalar independence heuristic
  • =store — store-level granularity
• --polly-tc-opt — do optimizations of tensor contractions based on pattern matching 🧚
• --polly-tiling — enable loop tiling 🦋
• --polly-vectorizer=<value> — select the vectorization strategy, choose wisely bestie:
  • =none — no Vectorization 🚫
  • =stripmine — strip-mine the outer loops so the loop-vectorizer actually triggers 👑
