like you want to benchmark on qemu, but I don't think qemu will give you representative performance numbers. </span><span style="color: rgb(50, 49, 48); font-family: "Segoe UI", "Segoe UI Web (West European)", "Segoe UI", -apple-system, BlinkMacSystemFont, Roboto, "Helvetica Neue", sans-serif;">So
yeah, for benchmarking I think a dev board would be best. A phone could work too, but then you need to be really careful in setting up the environment (frequency scaling etc.), but then I'm guessing running the llvm-suite might be tricky. Alternatively, there
are a few cloud services available that you can use to generate numbers, but I don't have any experience in setting that up, so don't know how easy/convenient that is. But I think I know which phab diff your query is related to, so will leave a comment there
too.</span></div>

<div style="margin:0">Hello, </div>
<div style="margin:0"><br>
</div>
<div style="margin:0">I am trying to run benchmark test for llvm with llvm-test-suite, but failed. I do not have an arm-linux board, but an android userdebug phone. So I planned to run on PC with qemu-arm.</div>
<div style="margin:0"><br>
</div>
<div style="margin:0">My step (on ubuntu 18.04)</div>
<div style="margin:0"><br>
</div>
<div style="margin:0">1. git clone <a href="https://github.com/llvm/llvm-test-suite">https://github.com/llvm/llvm-test-suite</a>
</div>
<div style="margin:0">2. apt-get install qemu arm-linux-gnueabihf-gcc -y</div>
<div style="margin:0">3. cd llvm-test-suite</div>
<div style="margin:0">4. mkdir build & cd build</div>
<div style="margin:0">5. cmake -DCMAKE_C_COMPILER=/home/llvm-dev-3/build/bin/clang -DCMAKE_C_FLAGS=" -O2 --target=arm-linux-gnueabihf -I/usr/arm-linux-gnueabihf/include/ " -DCMAKE_BUILD_TYPE=Release -DTEST_SUITE_RUN_UNDER=qemu-arm -DTEST_SUITE_BENCHMARKING_ONLY=On

<div style="margin:0"><br>
</div>
<div style="margin:0">But got errors like,</div>

<div style="margin:0"><br>
</div>
<div style="margin:0">The pthread.h does exist in /usr/arm-linux-gnueabihf/include/, why cmake still can not find it?</div>
<div style="margin:0"><br>
</div>
<div style="margin:0">Or any other suggestion to run benchmark on arm? Do I need to by a raspberry-pi board? Or qemu and anrdoird dev phone are OK enough?</div>
