Yes, it does on Debian unstable 32-bit PowerPC with the patches against LLVM-7, didn't test LLVM-8: root@kapitsa:/srv/llvm# clang-7 -cc1 -triple powerpc-gnu-linux-eabi -emit-obj -target-cpu ppc -target-feature +spe -O2 t.cpp t.cpp:23:1: warning: control reaches end of non-void function } ^ Stack dump: 0.
