[Qemu-devel] [PATCH] configure: Only build the s390-ccw bios if the compiler supports -march=z900

2019-01-14 Thread Thomas Huth
We want to build our s390-ccw bios with -march=z900 so that it also works with the oldest s390x CPU that we support with TCG. However, Clang on s390x does not support -march=z900 anymore, so we can not use this compiler to build the s390-ccw bios. Thus add a proper test to the configure script to
