Author: ed Date: Thu May 13 17:32:30 2010 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.
