Hello, all
I have two questions:
1) Is ./configure --cc=clang the correct way to enable clang
compilation of QEMU? Any other gotchas?
2) Did somebody compare QEMU compiled by gcc vs. QEMU compiled with
clang (in any sense: executable size, performance, etc.)?
Thanks in advance,
Aleksandar

You'll also want "--cxx=clang++", so the (few) C++ parts of
QEMU get compiled with the same toolchain.
It should just work -- clang is our default compiler for OSX
and is included in the CI and pre-merge tests on Linux.
thanks
