Summary

RootOrderingTest is a low-level unit test that creates values and uses them as vertices in a directed graph. These vertices were created using builder.create, but never freed, due to my insufficient understanding of the MLIR infrastructure.

You need to be erasing those ops using erase().

39

As you know here that getDefiningOp() is a ConstantOp, please use a way to assert. For eg:

assert(v[i].getDefiningOp());
cast<ConstantOp>(v[i].getDefiningOp()).erase();

Nit: unsigned here and below.

46–47

Please use ConstantIntOp -- that way, you can just pass i as the arg.

@bondhugula unsigned is an anti-pattern (unless working with bit-fields or other bit-manipulation), this has been widely documented I believe, both in C++ standardization paper (they are stuck with size_t in the standard library) and with conference talks like this one: https://www.youtube.com/watch?v=yG1OZ69H_-o

@bondhugula unsigned is an anti-pattern (unless working with bit-fields or other bit-manipulation), this has been widely documented I believe, both in C++ standardization paper (they are stuck with size_t in the standard library) and with conference talks like this one: https://www.youtube.com/watch?v=yG1OZ69H_-o

You need to be erasing those ops using erase().

As you know here that getDefiningOp() is a ConstantOp, please use a way to assert. For eg:

assert(v[i].getDefiningOp());
cast<ConstantOp>(v[i].getDefiningOp()).erase();
bondhugula: As you know here that `getDefiningOp()` is a `ConstantOp`, please use a way to assert. For eg…
v[i].getDefiningOp()->erase();

Please use ConstantIntOp -- that way, you can just pass i as the arg.
