> Hi @jeanPerier , yes, you are right. This patch changes the calling conversion of fp16 from GPRs to XMMs. So you need to update the runtime. If you are using compiler-rt, you could simply re-build it with trunk code, or at least after rGabeeae57 <https://reviews.llvm.org/rGabeeae570efff38dceccf68f5352809c58ffdda2>. If you are using your own runtime, you can solve the problem through the way in https://github.com/llvm/llvm-project/issues/56156

Thanks for the quick reply.  I was using a compiler-rt from the trunk source but not building it with a clang compiler compiled from the trunk. I did not know the version of clang used to compiled compiler-rt mattered that much. Using clang from the trunk (or at least after the commit you mentionnned) solved my problem. Thanks !
