// RenderScriptRuntimeModulePass is a simple llvm::ModulesPass that is used
// during expression evaluation to apply RenderScript-specific fixes for
// expression evaluation. In particular this is used to make expression IR
// conformant with the ABI generated by the slang frontend. This ModulePass is
// executed in ClangExpressionParser::PrepareForExecution whenever an
// expression's DWARF language is eLanguageTypeExtRenderscript
