[LLVMdev] Are integer types primitive?

[Joey Gouly]

So, I did a quick experiment with the following patch:

diff --git a/include/llvm/IR/Type.h b/include/llvm/IR/Type.h
index 1bf8789..16bd376 100644
--- a/include/llvm/IR/Type.h
+++ b/include/llvm/IR/Type.h
@@ -73,8 +73,8 @@ public:
     VectorTyID,      ///< 15: SIMD 'packed' format, or other vector type

     NumTypeIDs,                         // Must remain as last defined ID
-    LastPrimitiveTyID = X86_MMXTyID,
-    FirstDerivedTyID = IntegerTyID
+    LastPrimitiveTyID = IntegerTyID,
+    FirstDerivedTyID = FunctionTyID
   };

 private:

'ninja check-all' passes. The only users of isPrimitiveType also check
isIntegerTy.
