+               //
+               //    On the other hand, because our presentation format presents

+// Currently, several factors are introduced to reduce the need for mixing
+// string and C++ if-else code.
+//
+// Usage:
+// To build: @$3 asm("@%3 add.s32 %0, %1, %2;" : "=r"(i) : "r"(j), "r"(k),
+// "b"(p));
+//
+// PTXBuilder builder;
+// auto& add = builder.create<>();
+// add.predicate(pVal).o("lo").o("u32"); // add any suffix
+// // predicate here binds %0 to pVal, pVal is a mlir::Value
+//
+// auto* iOpr = builder.newOperand(iVal, "r"); // %1 bind to iVal
+// auto* jOpr = builder.newOperand(jVal, "r"); // %2 bind to jVal
+// auto* kOpr = builder.newOperand(kVal, "r"); // %3 bind to kVal
+// add(iOpr, jOpr, kOpr).predicate(predVal);   // set operands and predicate
+//
+// To get the asm code:
+// builder.dump()
+//
+// To get all the mlir::Value used in the PTX code,
+//
+// builder.getAllMlirArgs() // get {pVal, iVal, jVal, kVal}
+//
+// To get the string containing all the constraints with "," separated,
+// builder.getConstraints() // get "=r,r,k"
+//
+// PTXBuilder can build a PTX asm with multiple instructions, sample code:
+//
+// PTXBuilder builder;
+// auto& mov = builder.create("mov");
+// auto& cp = builder.create("cp");
+// mov(...);
+// cp(...);
+// This will get a PTX code with two instructions.
+//
+// Similar to a C function, a declared PTXInstr instance can be launched
+// multiple times with different operands, e.g.
+//
+//   auto& mov = builder.create("mov");
+//   mov(... some operands ...);
+//   mov(... some different operands ...);
+//

+TritonGPU Tensors differ from usual tensors in that they contain a _layout_ attribute which determines
+how the data should be partitioned across CUDA threads. Formally speaking, we define a layout as a function
+\mathcal{L} that maps a multi-dimensional tensor index $i \in \mathbb{Z}^d$ to a set of integers T corresponding
+to the indices of the CUDA threads allowed to access some data at index $i$.
+
+For example, let us consider the layout function:
+\mathcal{L}(0, 0) = {0, 4}
+\mathcal{L}(0, 1) = {1, 5}
+\mathcal{L}(1, 0) = {2, 6}
+\mathcal{L}(1, 1) = {3, 7}
+
+Then, attaching $\mathcal{L} to a tensor $T$ would mean that:
+- T[0,0] is owned by both cuda thread 0 and 4
+- T[0,1] is owned by both cuda thread 1 and 5
+- T[1,0] is owned by both cuda thread 2 and 6
+- T[1,1] is owned by both cuda thread 3 and 7
+
+Right now, Triton implements two classes of layouts: shared, and distributed.

+      This operation inserts a tensor `$src` into another tensor `$dst` as specified by the operation’s
+      `$index` argument and `$axis` attribute.
+
+      It returns a copy of `$dst` with the proper slice updated asynchronously with the value of `$src`.
+      This operation is non-blocking, and `$results` will have the updated value after the corresponding async_wait.
+
+      The insert_slice_async operation supports the following arguments:
+
+      * src: the tensor that is inserted.
+      * dst: the tensor into which the `$src` tensor is inserted.
+      * index: the index of the `$src` tensor at the given `$axis` from which the `$dst` tensor is inserted into
+      * mask: optional tensor-rank number of boolean masks which specify which
+              elements of the `$src` tensor are inserted into the `$dst` tensor.
+      * other: optional tensor-rank number of other tensors which specify what
+              values are inserted into the `$dst` tensor if the corresponding
+              element of the `$mask` tensor is false.
+
+      In the future, we may decompose this operation into a sequence of:
+
+      * `async` operation to specify a sequence of asynchronous operations
+      * `load` operation to load a tensor from global memory
+      * `insert_slice` operations to insert the `$src` tensor into the `$dst` tensor
