Global instruction selection
Webtreatment of global code motion, which lets the selection of instructions to be global for an entire function. The representation is compatible with state-of-the-art compilers; the paper uses LLVM [26] as compiler infrastructure. However, the very reason of the proposed approach is that instruction selec-tion can be expressed as a constraint model.
