The `cfcmsa` and `ctcmsa` instructions accept index of MSA control register. The MIPS64 SIMD Architecture define eight MSA control registers. But register index for `cfcmsa` and `ctcmsa` instructions might be any number in 0..31 range. If the index is greater then 7, `cfcmsa` writes zero to the destination registers and `ctcmsa` does nothing [1].

The LLVM Compiler Infrastructure
This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments.
