Who knows, how to clang Qemu?
I try with
./configure --target-list=x86_64-softmmu --enable-debug --disable-virtfs
--enable-werror --audio-drv-list=oss --extra-cflags=-Wall --enable-sanitizers
--cc=clang --cxx=clang++
make -j9
but get the following error:
/tmp/linuxboot_dma-6712c0.s: Assembler messages:
/tmp/linuxboot_dma-6712c0.s:473: Error: inconsistent uses of .cfi_sections
clang: error: assembler command failed with exit code 1 (use -v to see
invocation)
make[1]: *** [linuxboot_dma.o] Error 1
make[1]: *** Waiting for unfinished jobs....
SIGN pc-bios/optionrom/linuxboot.bin
LINK ivshmem-client
