This test runs
mlir-opt %s | mlir-opt %s | FileCheck
to test the round trip behavior, but the second command takes input from the pipe, not the lit test, so it should bemlir-opt %s | mlir-opt | FileCheck
.For some reason I haven't figured out, this causes ~50% flakiness when testing in certain environments (not reproducible in my shell, but reproduces in an internal buildbot), due to the pipeline raising
SIGPIPE
.Test added in #148424.
