    perf python: Check if clang supports -fno-semantic-interposition · 9a00df31
    Arnaldo Carvalho de Melo authored
    The set of C compiler options used by distros to build python bindings
    may include options that are unknown to clang, we check for a variety of
    such options, add -fno-semantic-interposition to that mix:
    
    This fixes the build on, among others, Manjaro Linux:
    
        GEN      /tmp/build/perf/python/perf.so
      clang-9: error: unknown argument: '-fno-semantic-interposition'
      error: command 'clang' failed with exit status 1
      make: Leaving directory '/git/perf/tools/perf'
    
      [perfbuilder@602aed1c266d ~]$ gcc -v
      Using built-in specs.
