// This test relies on us piping stdout and that there's only a single
// executable (otherwise we'd need to look at files and that's harder
// cross-platform). Real automation of this requires xargs: compile and dump a
// directory of .mlir sources by specifying a path to the dump flag instead
// of `-` (indicating stdout) and then ls | xargs them to iree-compile or
// iree-opt.
//
// Example of dumping per-dispatch executable sources and compiling each to
// their platform binary form, dumping their MLIR prior to lowering into the
// backend representation (SPIR-V/LLVM-IR/etc):
//  iree-compile some_input.mlir -o ignored.mlir \
//      --iree-hal-target-device=local \
//      --iree-hal-local-target-device-backends=vmvx \
//      --iree-hal-dump-executable-sources-to=sources/ | \
//  ls -1 sources/ | xargs -i sh -c "iree-compile sources/{} --compile-mode=hal-executable --mlir-print-ir-before=iree-hal-serialize-all-executables"
//
// NOTE: executable sources are not runnable: they only exist to allow for
// iteration on executable translation. If you want to run them you need
// corresponding host code to dispatch them and can use benchmarks instead.
//
// If modifying the sources and wanting to see the changes in a full program the
// --iree-hal-substitute-executable-sources-from= flag can be used to substitute
// one or more executables dumped with this command from a path or for
// individual executables one or more `executable_name=file.mlir` pairs can be
// repeated in `--iree-hal-substitute-executable-source=`.
