[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/tools/llvm-exegesis/lib/ParallelSnippetGenerator.cpp:318-319
+  std::vector<CodeTemplate> Result;
+  for (RegRandomizationStrategy S : enum_seq_inclusive(
+           RegRandomizationStrategy::FIRST, RegRandomizationStrategy::LAST)) {
+    CodeTemplate CurrCT = CT.clone();
----------------
To be fair, one thing we don't do here, is elimination of unreasonable choices.
If there is only a single use reg, there is no difference
between `SingleStaticUseRegPerOperand` and `SingleStaticUseReg`.
