// TOTHINK: Open issue: should we use DAG lists in Tool specifications
|
|
// or change to something like
|
|
|
|
// def LLVMGccC : < Tool<
|
|
// [ InLanguage<"c">,
|
|
// PrefixListOption<"Wl", [UnpackValues, PropertyName<Arg>, ...]>
|
|
// ...] ?
|
|
|
|
// DAG lists look more aesthetically pleasing to me.
