Would the targets supporting OpenCL need to define their own behavior in
`getDefaultDenormalModeForType`?
================
Comment at: clang/include/clang/Driver/ToolChain.h:619
+ const llvm::fltSemantics *FPType = nullptr) const {
+ // FIXME: This should be IEEE when default handling is fixed.
+ return llvm::DenormalMode::Invalid;

Can you elaborate what has to be done in order to fix this?
