Currently I would recommend using the cmake/lit version of the test-suite. You typically do something like:<br class="">
<br class="">
mkdir build && cd build<br class="">
cmake -GNinja -DCMAKE_C_COMPILER=/path/to/<wbr class="">my/clang -DTEST_SUITE_ARCH_FLAGS="-arch arm64" /path/to/test-suite<br class="">
ninja # to build the benchmarks<br class="">
llvm-lit # to run the benchmarks<br class="">
<br class="">
You should check "ccmake"/"cmake -LA" to learn about the available options as well as llvm-lit. You can either use llvm-lit from an llvm build or use the pypy packaged version (pip install lit). The cmake/lit version has no support to run custom backends through llc at the moment, you need to have a clang version that accepts -arch XXX for your target.<br class=""></blockquote><div class="">Sorry I didn't explain well.

Unfortunately this system can get complicated and is not documented much.
