Mark Heffernan ba9e336c90 Add new llvm.loop.unroll.enable metadata. ... This change adds the unroll metadata "llvm.loop.unroll.enable" which directs the optimizer to unroll a loop fully if the trip count is known at compile time, and unroll partially if the trip count is not known at compile time. This differs from "llvm.loop.unroll.full" which explicitly does not unroll a loop if the trip count is not known at compile time. The "llvm.loop.unroll.enable" is intended to be added for loops annotated with "#pragma unroll". llvm-svn: 244466		2015-08-10 17:28:08 +00:00
