[gc.statepoint] Change gc.statepoint intrinsic's return type to token type instead of i32 type

[• chenli]

Summary

This patch changes gc.statepoint intrinsic's return type to token type instead of i32 type. Using token types could prevent LLVM to merge different gc.statepoint nodes into PHI nodes and cause further problems with gc relocations. The patch also changes the way on how gc.relocate and gc.result look for their corresponding gc.statepoint on unwind path. The current implementation uses the selector value extracted from a { i8*, i32 } landingpad as a hook to find the gc.statepoint, while the patch directly uses a token type landingpad (http://reviews.llvm.org/D15405) to find the gc.statepoint.

Looks good. (I didn't carefully read through all the test changes so I am assuming that they are all replacing i32 with token type).

[mjacob]

LGTM, too. I skimmed over the tests, and they seem to be fine. I can't comment on the invoke-related changes, though.

These should either be updated or removed before committing this revision. I'd prefer the last option because these intrinsics were deprecated about 11 months ago. I'll prepare a revision for that.

Agreed.

 SSA value ``%obj.relocated`` which represents the potentially changed value of
 ``%obj`` after the safepoint and update any following uses appropriately.  The 
 resulting relocation sequence is:
 
 .. code-block:: llvm
 
   define i8 addrspace(1)* @test1(i8 addrspace(1)* %obj) 
          gc "statepoint-example" {
-    %0 = call i32 (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj)
-    %obj.relocated = call coldcc i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(i32 %0, i32 7, i32 7)
+    %0 = call token (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj)
+    %obj.relocated = call coldcc i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(token %0, i32 7, i32 7)
     ret i8 addrspace(1)* %obj.relocated
   }
 
 Ideally, this sequence would have been represented as a M argument, N
 return value function (where M is the number of values being
 relocated + the original call arguments and N is the original return
 value + each relocated value), but LLVM does not easily support such a
 representation.

 If we extend our previous example to include a pointless derived pointer, 
 we get:
 
 .. code-block:: llvm
 
   define i8 addrspace(1)* @test1(i8 addrspace(1)* %obj) 
          gc "statepoint-example" {
     %gep = getelementptr i8, i8 addrspace(1)* %obj, i64 20000
-    %token = call i32 (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj, i8 addrspace(1)* %gep)
-    %obj.relocated = call i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(i32 %token, i32 7, i32 7)
-    %gep.relocated = call i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(i32 %token, i32 7, i32 8)
+    %token = call token (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj, i8 addrspace(1)* %gep)
+    %obj.relocated = call i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(token %token, i32 7, i32 7)
+    %gep.relocated = call i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(token %token, i32 7, i32 8)
     %p = getelementptr i8, i8 addrspace(1)* %gep, i64 -20000
     ret i8 addrspace(1)* %p
   }
 
 Note that in this example %p and %obj.relocate are the same address and we
 could replace one with the other, potentially removing the derived pointer
 from the live set at the safepoint entirely.  
 

 
 .. code-block:: llvm
 
   @flag = thread_local global i32 0, align 4
 
   define i8 addrspace(1)* @test1(i8 addrspace(1) *%obj)
          gc "hypothetical-gc" {
 
-    %0 = call i32 (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()* @foo, i32 0, i32 1, i32* @Flag, i32 0, i8 addrspace(1)* %obj)
-    %obj.relocated = call coldcc i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(i32 %0, i32 7, i32 7)
+    %0 = call token (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()* @foo, i32 0, i32 1, i32* @Flag, i32 0, i8 addrspace(1)* %obj)
+    %obj.relocated = call coldcc i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(token %0, i32 7, i32 7)
     ret i8 addrspace(1)* %obj.relocated
   }
 
 During lowering, this will result in a instruction selection DAG that looks
 something like:

 ``gc.result`` extracts the result of the original call instruction
 which was replaced by the ``gc.statepoint``.  The ``gc.result``
 intrinsic is actually a family of three intrinsics due to an
 implementation limitation.  Other than the type of the return value,
 the semantics are the same.

 Semantics:
 """"""""""
 
 The ``gc.result`` represents the return value of the call target of
 the ``statepoint``.  The type of the ``gc.result`` must exactly match
 the type of the target.  If the call target returns void, there will
 be no ``gc.result``.
 
 A ``gc.result`` is modeled as a 'readnone' pure function.  It has no
 side effects since it is just a projection of the return value of the
 previous call represented by the ``gc.statepoint``.

 A ``gc.relocate`` returns the potentially relocated value of a pointer
 at the safepoint.
 
 Operands:

 safepoint sequence of which this ``gc.relocation`` is a part.

 The second argument is an index into the statepoints list of arguments
 which specifies the allocation for the pointer being relocated.
 This index must land within the 'gc parameter' section of the
 statepoint's argument list.  The associated value must be within the
 object with which the pointer being relocated is associated. The optimizer
 is free to change *which* interior derived pointer is reported, provided that

 distinguish between GC references and non-GC references in IR it is given.
 
 As an example, given this code:
 
 .. code-block:: llvm
 
   define i8 addrspace(1)* @test1(i8 addrspace(1)* %obj) 
          gc "statepoint-example" {
-    call i32 (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 5, i32 0, i32 -1, i32 0, i32 0, i32 0)
+    call token (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 5, i32 0, i32 -1, i32 0, i32 0, i32 0)
     ret i8 addrspace(1)* %obj
   }
 
 The pass would produce this IR:
 
 .. code-block:: llvm
 
   define i8 addrspace(1)* @test1(i8 addrspace(1)* %obj) 
          gc "statepoint-example" {
-    %0 = call i32 (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 5, i32 0, i32 -1, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj)
-    %obj.relocated = call coldcc i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(i32 %0, i32 12, i32 12)
+    %0 = call token (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 5, i32 0, i32 -1, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj)
+    %obj.relocated = call coldcc i8 addrspace(1)* @llvm.experimental.gc.relocate.p1i8(token %0, i32 12, i32 12)
     ret i8 addrspace(1)* %obj.relocated
   }
 
 In the above examples, the addrspace(1) marker on the pointers is the mechanism
 that the ``statepoint-example`` GC strategy uses to distinguish references from
 non references.  Address space 1 is not globally reserved for this purpose.
 
 This pass can be used an utility function by a language frontend that doesn't 
.. code-block:: llvm
   }
 
 
 This pass would produce the following IR:
 
 .. code-block:: llvm
 
   define void @test() gc "statepoint-example" {
-    %safepoint_token = call i32 (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @do_safepoint, i32 0, i32 0, i32 0, i32 0)
-    %safepoint_token1 = call i32 (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 0)
+    %safepoint_token = call token (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @do_safepoint, i32 0, i32 0, i32 0, i32 0)
+    %safepoint_token1 = call token (i64, i32, void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 2882400000, i32 0, void ()* @foo, i32 0, i32 0, i32 0, i32 0)
     ret void
   }
 
 In this case, we've added an (unconditional) entry safepoint poll and converted the call into a ``gc.statepoint``.  Note that despite appearances, the entry poll is not necessarily redundant.  We'd have to know that ``foo`` and ``test`` were not mutually recursive for the poll to be redundant.  In practice, you'd probably want to your poll definition to contain a conditional branch of some form.
 
 
 At the moment, PlaceSafepoints can insert safepoint polls at method entry and 
 loop backedges locations.  Extending this to work with return polls would be
