mlir reproducer file
To reproduce
(1) build the MLIR binaries mlir-opt/mlir-cpu-runner
(2) (optional) build support lib ibmlir_runner_utils.so, for vector.print
(2) run this on command line
mlir-opt \
-convert-loop-to-std \
--convert-vector-to-llvm \
--convert-std-to-llvm test-transfer-read.mlir | \
mlir-cpu-runner \
-e entry -entry-point-result=void \
-shared-libs=<path-to>/libmlir_runner_utils.so
Crashes as follows:
