New Revision: 208038
URL: http://svn.freebsd.org/changeset/base/208038

Log:
  Crude hack to make LLVM build on FreeBSD/arm.
  
  LLVM needs a function to flush the icache of certain memory regions.
  glibc has a function for it called __clear_cache(), but FreeBSD's libc
  doesn't have it. I don't care about flushing the icache at all, because
  it's only used when JITting, which we are not going to do with Clang.
