Summary: This threshold limited FunctionAttrs ability to prove arguments to be read-only. In NVPTX, a specialized instruction ld.global.nc can be used to load memory with non-coherent texture cache. We notice that in SHOC [1] benchmark, some function arguments are not marked with readonly because FunctionAttrs reaches a hardcoded threshold when analysis uses. Removing this threshold won't cause significant regression in compilation time, because the worst-case time complexity of the algorithm is still O(# of instructions) for each parameter.

Low Level Virtual Machine (LLVM) ================================ This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments. LLVM is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt. Please see the documentation provided in docs/ for further assistance with LLVM, and in particular docs/GettingStarted.rst for getting started with LLVM and docs/README.txt for an overview of LLVM's documentation setup. If you're writing a package for LLVM, see docs/Packaging.rst for our suggestions.
