...e interested, I posted two new ideas for changes to the LLVM IR. The first is basically a cleanup, the second is a major new feature: Eliminating the 'Void' Type: http://nondot.org/sabre/LLVMNotes/EliminatingVoid.txt Aggregates as First Class Values: http://nondot.org/sabre/LLVMNotes/FirstClassAggregates.txt Thanks to Dan Gohman for convincing me that aggregates as first class values is really possible, I think it is a great idea. -Chris

...is might add a cost if you use {} for void. Also, there are an infinite number of different ways of returning void: return {} or {{}} or {{{}}} etc, not to mention returning zero length arrays. I guess that's life. > Aggregates as First Class Values: > http://nondot.org/sabre/LLVMNotes/FirstClassAggregates.txt Does this mean that vector types can be removed in favour of ordinary arrays? If not, maybe at least vectors should be changed to derive from array types, and no longer be primitive types. This would make it easier to fix a bunch of problems with vector types, for example that the primit...
