// are an exact match.
//
// This file has two identical copies. The primary copy lives in LLVM and
// the other one sits in compiler-rt/lib/builtins/cpu_model directory. To make
// changes in this file, first modify the primary copy and copy it over to
// compiler-rt. compiler-rt tests will fail if the two files are not synced up.
