  Hi Chinmay,

the problem with Clang on Travis [*] still seems to persist:

  https://app.travis-ci.com/github/huth/kvm-unit-tests/jobs/639614142

Could you please have a look?

  Thanks,
   Thomas


[*] This already happened with Nicolas' last version:

I managed to get access to a ppc64 machine. The error is:

/tmp/pmu-eab466.s: Assembler messages:
/tmp/pmu-eab466.s:1649: Error: unrecognized opcode: `ldat'
clang: error: assembler command failed with exit code 1 (use -v to see 
invocation)
make: *** [<builtin>: powerpc/pmu.o] Error 1

  HTH,
