[Statepoints] Support for "patchable" statepoints.

[sanjoy]

Summary

This change adds two new parameters to the statepoint intrinsic, i64 id
and i32 num_patch_bytes. id gets propagated to the ID field
in the generated StackMap section. If the num_patch_bytes is
non-zero then the statepoint is lowered to num_patch_bytes bytes of
nops instead of a call (the spill and reload code remains unchanged).
A non-zero num_patch_bytes is useful in situations where a language
runtime requires complete control over how a call is lowered.

This change brings statepoints one step closer to patchpoints. With
some additional work (that is not part of this patch) it should be
possible to get rid of TargetOpcode::STATEPOINT altogether.

PlaceSafepoints generates statepoint wrappers with both id and
num_patch_bytes set to 0. This can be made more sophisticated
later.

Typo:

@llvm.experimental.gc.statepoint.p0f_isVoidfi64 0, i32 0, (void ()* @foo, i32 0

should be:

An assertion that NumPatchBytesVal fits in 32 bits might be nice here.

590–591

It might be nice to move the definition of Ops and the subsequent pushes closer to their use (i.e. somewhere near line 650).

Might be nice to have a check that NumPatchBytes fits in 32 bits. This condition should be satisfied by the intrinsic signature, but a little paranoia isn't necessarily bad. No strong feeling here.

1553

No need to fix this now, necessarily, but it would be nice to replace these literals with the relevant constants from Statepoint.h.

Changed to ISP.getFlags().

Agreed. I added an assert (not an Assert) for this.

Agreed; good idea, but should probably happen in a separate patch.

LGTM modulo the comments above.

Still one extra ( before void ()* @foo, ...

3410–3411

An assertion that the result type remains a pointer would be helpful. This assert certainly helped me find and correct a few calls to gc.relocate that I hadn't fixed up when I was adjusting things for the GC transition change.

This came in via a different change by Chen, I'll ask him to take a look.

I could not find a test-case for valid patchable-statepoints. How is the Nop emission tested?

Thanks.

I will submit a patch to assert gc_relocate returns a pointer type.

Thanks.

There is a new test case in test/CodeGen/X86/statepoint-call-lowering.ll.

• fix typo in Statepoints.rst
• add a test case testing for correct lowering of the id parameter in statepoints

[reames]

LGTM pending minor documentation and style comments. No further review needed.

I'd comment here that the meaning is up to the user. It's an opaque value to LLVM. You might also comment that it's not guaranteed to be unique due to code duplication.

321

More detail is needed here. What are the semantics of this patchable section? Is it structured to be atomically patchable in any way?

329

Merge w/previous paragraph.

lib/Target/X86/X86MCInstLower.cpp

Just to be clear, this is not trying to implement the shadow behaviour of a patchpoint right? It's just raw patchable bytes? Please clarify this in the documentation.

lib/Transforms/Scalar/PlaceSafepoints.cpp

889–890

I would mildly prefer you use the ID which was hard coded in the stackmap code before. No reason to change behaviour if it's not needed.

[sanjoy]

docs/Statepoints.rst

318

Done.

321

Done. I did not mention about the section begin atomically patchable since that seems somewhat tangential, but I've mentioned that there are no alignment guarantees.

Done.

Done.

[dougk]

The assertion NumPatchBytes >= 0 is tautologically true because the type is 'uint'.

The assertion NumPatchBytes >= 0 is tautologically true because the type is 'uint'.

Thank you for catching that, I'll fix it.

 ``%obj`` after the safepoint and update any following uses appropriately.  The 
 resulting relocation sequence is:

   define i8 addrspace(1)* @test1(i8 addrspace(1)* %obj) 
          gc "statepoint-example" {
-    %0 = call i32 (void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(void ()* @foo, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj)
+    %0 = call i32 (void ()*, i32, i32, ...)* @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, (void ()* @foo, i32 0, i32 0, i32 0, i8 addrspace(1)* %obj)

     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

 Overview:
 """""""""
 
 The statepoint intrinsic represents a call which is parse-able by the
 runtime.
 
 Operands:
 """""""""
 
+The 'id' operand is a statepoint specific ID that is reported as the
+ID field in the generated stackmap.
+
+If 'num patch bytes' is non-zero then the statepoint is lowered to a
+'num patch bytes' byte long nop sequence instead of a call.
+
 The 'target' operand is the function actually being called.  The
 target can be specified as either a symbolic LLVM function, or as an
 arbitrary Value of appropriate function type.  Note that the function
 type must match the signature of the callee and the types of the 'call
 parameters' arguments.
 
+If 'num patch bytes' is non-zero then 'target' has to be the constant
+pointer null of the appropriate function type.
+
 The '#call args' operand is the number of arguments to the actual
 call.  It must exactly match the number of arguments passed in the
 'call parameters' variable length section.
 
 The 'flags' operand is used to specify extra information about the
 statepoint. This is currently only used to mark certain statepoints
 as GC transitions. This operand is a 64-bit integer with the following
 layout, where bit 0 is the least significant bit:
* Variable number of Locations pairs, one pair for each unique pointer
   statepoint. There may be fewer pairs then gc parameters in the IR
   statepoint. Each *unique* pair will occur at least once; duplicates
   are possible.
 
 Note that the Locations used in each section may describe the same
 physical location.  e.g. A stack slot may appear as a deopt location,
 a gc base pointer, and a gc derived pointer.
 
-The ID field of the 'StkMapRecord' for a statepoint is meaningless and
-it's value is explicitly unspecified.
-
 The LiveOut section of the StkMapRecord will be empty for a statepoint
 record.

 ; Tests the name mangling performed by the codepath following
 ; getMangledTypeStr(). Only tests that code with the various manglings
 ; run fine: doesn't actually test the mangling with the type of the
 ; arguments. Meant to serve as an example-document on how the user
 ; should do name manglings.
 
 ; Exercise the most general case, llvm_anyptr_type, using gc.relocate
 ; and gc.statepoint. Note that it has nothing to do with gc.*
 ; functions specifically: any function that accepts llvm_anyptr_type
 ; will serve the purpose.
