beanz added inline comments.
================
Comment at: clang/lib/CodeGen/CGHLSLRuntime.cpp:47
+void addDisableOptimizations(llvm::Module &M) {
+ StringRef Key = "dx.disable_optimizations";
+ M.addModuleFlag(llvm::Module::ModFlagBehavior::Override, Key, 1);
----------------
What does this translate to in codegen?
================
Comment at: clang/lib/Driver/ToolChains/HLSL.cpp:170
+ if (OStr == "d") {
+ DAL->AddFlagArg(nullptr, Opts.getOption(options::OPT_dxc_opt_disable));
+ DAL->AddFlagArg(nullptr, Opts.getOption(options::OPT_O0));
----------------
Since `dxc_opt_disable` is paired with passing `-O0` do we need the flag at
all, or can we just set the module flag if `OptimizationLevel` is 0?
