Segmentation fault in Handshake buffer insertion #9370
Description
Test commit
417a5112947d9889cad54cb5b2110b37978b86b8
Description
The -handshake-insert-buffers=strategy=cycles pass crashes with a null pointer dereference when the pass is attempting to identify users of result values (for buffering).
Steps to reproduce
- Minimal MLIR program (test.mlir)
"builtin.module"()({
"handshake.func"()<{function_type=(none,none,none)->(none,none)}>({
^bb0(%arg0:none,%arg1:none,%arg2:none):
%0:2 = "handshake.control_merge"(%arg0,%arg1):(none,none)->(none,index)
"handshake.return"(%0#0,%arg2):(none,none)->()
}){argNames=["arg0","arg1","arg2"],resNames=["out0","out1"],sym_name="main"}:()->()
}):()->()
Command
circt-opt -handshake-insert-buffers=strategy=cycles test.mlir
Output
PLEASE submit a bug report to https://github.com/llvm/circt and include the crash backtrace.
