   ClangBuiltin<"__builtin_amdgcn_ds_swizzle">,
-  Intrinsic<[llvm_i32_ty], [llvm_i32_ty, llvm_i32_ty],
-            [IntrNoMem, IntrConvergent, IntrWillReturn,
+  DefaultAttrsIntrinsic<[llvm_i32_ty], [llvm_i32_ty, llvm_i32_ty],
+            [IntrNoMem, IntrConvergent,
----------------
Shouldn't be default, nosync is wrong


================
Comment at: llvm/include/llvm/IR/IntrinsicsAMDGPU.td:1649-1686
 def int_amdgcn_icmp :
-  Intrinsic<[llvm_anyint_ty], [llvm_anyint_ty, LLVMMatchType<1>, llvm_i32_ty],
-            [IntrNoMem, IntrConvergent, IntrWillReturn,
+  DefaultAttrsIntrinsic<[llvm_anyint_ty], [llvm_anyint_ty, LLVMMatchType<1>, llvm_i32_ty],
+            [IntrNoMem, IntrConvergent,
              ImmArg<ArgIndex<2>>]>;
 
 def int_amdgcn_fcmp :
+  DefaultAttrsIntrinsic<[llvm_anyint_ty], [llvm_anyfloat_ty, LLVMMatchType<1>, llvm_i32_ty],
----------------
Not default, probably should not get nosync

+  DefaultAttrsIntrinsic<[llvm_i32_ty], [llvm_i32_ty],
+            [IntrNoMem, IntrConvergent]>;
----------------
Shouldn't get nosync

Not sure about these ones, but maybe shouldn't get nosync


================
Comment at: llvm/include/llvm/IR/IntrinsicsAMDGPU.td:2020-2044
 class AMDGPUWmmaIntrinsic<LLVMType AB, LLVMType CD> :
-  Intrinsic<

     [CD],               // %D
     [
       AB,               // %A
       AB,               // %B
       LLVMMatchType<0>, // %C
----------------
Also not sure about nosync for these

 def int_amdgcn_reloc_constant : Intrinsic<

Defaults
