  "message": "Add HAL CTS tests using executables. (#7982)\n\nFixes https://github.com/google/iree/issues/5678 (for `executable_cache_test`, tests issuing dispatches can follow on later)\r\n\r\nTests are filtered based on the HAL driver and compiler target being enabled as well as the presence of a new `COMPILER_TARGET_BACKEND` parameter to the `iree_hal_cts_test_suite()` function.\r\n\r\nIf all of those conditions are met, executable testdata is generated using the new `-iree-mlir-to-hal-executable` translation mode and relevant tests in the suite get to load and reference the generated data.\r\n\r\n---\r\n\r\nRough edges:\r\n\r\n* ~~`iree_file_toc_t` definition copy/paste from `generate_embed_data` (since leaf binaries provide their own implementations)~~\r\n* Specifying executable formats in CMake is hacky (`\"\\\"embedded-elf-\\\" IREE_ARCH\"`)\r\n* We may also want to test the system loader as well as the embedded loader, which is possible with another `iree_hal_cts_test_suite()` call\r\n\r\nI was also expecting the CMake to be a bit gnarly, and it is. Could maybe refactor into some helper functions or golf on the logic a bit. The interface to each HAL implementation is pretty nice, but the new implicit dependency on `iree-translate` makes it harder to use with out-of-tree runtime HAL drivers + compiler targets. Could pass `TRANSLATE_TOOL` as well 🤔 ",
