Description

This works:

$ circt-opt simple_arith.mlir --lower-scf-to-calyx --calyx-remove-comb-groups --canonicalize --lower-calyx-to-fsm

But the following (without the --canonicalize) triggers an assertion:

$ circt-opt simple_arith.mlir --lower-scf-to-calyx --calyx-remove-comb-groups --lower-calyx-to-fsm
circt-opt: /home/xerpi/Desktop/Research/circt/llvm/llvm/include/llvm/ADT/SmallVector.h:303: T& llvm::SmallVectorTemplateCommon<T, <template-parameter-1-2> >::front() [with T = std::pair<mlir::Operation*, circt::fsm::StateOp>; <template-parameter-1-2> = void; reference = std::pair<mlir::Operation*, circt::fsm::StateOp>&]: Assertion `!empty()' failed

simple_arith.mlir can be found here.

Backtrace:

circt-opt simple_arith.mlir --lower-scf-to-calyx --calyx-remove-comb-groups --lower-calyx-to-fsm   
circt-opt: /home/xerpi/Desktop/Research/circt/llvm/llvm/include/llvm/ADT/SmallVector.h:303: T& llvm::SmallVectorTemplateCommon<T, <template-parameter-1-2> >::front() [with T = std::pair<mlir::Operation*, circt::fsm::StateOp>; <template-parameter-1-2> = void; reference = std::pair<mlir::Operation*, circt::fsm::StateOp>&]: Assertion `!empty()' failed.
PLEASE submit a bug report to https://github.com/llvm/circt and include the crash backtrace.
