The lastest version is for 7.8. And the hash at the last field of the branch name is the hash for git. You can checkout the version using this hash, like git checkout 725bcedcb69 <https://github.com/linzj/llvm-toy/tree/arm-tf-7_8_279_17_725bcedcb69>. You should checkout the LLVM version 8, the final release version, then patch it with the llvm-patch-by-far.patch, and build it to libLLVM-8.so.The build script can be referred to config32.sh <https://github.com/linzj/myscripts/blob/master/buildscript/llvm/config32.sh> . Then patch v8 with v8.patch. Then rsync src/ to v8/src/. Then copy libLLVM-8.so to v8/lib/ Then you can build it with chrome. Oh, don't forget to add "UC_BUILD_TF_LLVM_BACKEND" to defines.
