Adhemerval Zanella [Mon, 11 Jan 2016 19:55:27 +0000 (19:55 +0000)]
[sanitizer] [msan] Fix origin store of array types

This patch fixes the memory sanitizer origin store instrumentation for
array types.  This can be triggered by cases where frontend lowers
function return to array type instead of aggregation.

For instance, the C code:

struct mypair {
 int64_t x;
 int y;

mypair my_make_pair(int64_t x, int y)  {
 mypair p;
 p.x = x;
 p.y = y;
 return p;

int foo (int p)
  mypair z = my_make_pair(p, 0);
  return z.y + z.x;

It will be lowered with target set to aarch64-linux and -O0 to:

define i32 @_Z3fooi(i32 %p) #0 {
%call = call [2 x i64] @_Z12my_make_pairxi(i64 %conv, i32 0)
%1 = bitcast %struct.mypair* %z to [2 x i64]*
store [2 x i64] %call, [2 x i64]* %1, align 8

The origin store will emit a 'icmp' to test each store value again the
TLS origin array.  However since 'icmp' does not support ArrayType the
memory instrumentation phase will bail out with an error.

This patch change it by using the same strategy used for struct type on

It fixes the 'test/msan/insertvalue_origin.cc' for aarch64 (the -O0 case).

[Orc] Add support for remote JITing to the ORC API.

This patch adds utilities to ORC for managing a remote JIT target. It consists

1. A very primitive RPC system for making calls over a byte-stream.  See
RPCChannel.h, RPCUtils.h.

2. An RPC API defined in the above system for managing memory, looking up
symbols, creating stubs, etc. on a remote target. See OrcRemoteTargetRPCAPI.h.

3. An interface for creating high-level JIT components (memory managers,
callback managers, stub managers, etc.) that operate over the RPC API. See

4. A helper class for building servers that can handle the RPC calls. See

The system is designed to work neatly with the existing ORC components and
functionality. In particular, the ORC callback API (and consequently the
CompileOnDemandLayer) is supported, enabling lazy compilation of remote code.

Assuming this doesn't trigger any builder failures, a follow-up patch will be
committed which tests these utilities by using them to replace LLI's existing
remote-JITing demo code.

[ADT] Add a sum type abstraction for pointer-like types.

This is a much more general and powerful form of PointerUnion. It
provides a reasonably complete sum type (from type theory) for
pointer-like types. It has several significant advantages over the
existing PointerUnion infrastructure:

1) It allows more than two pointer types to participate without awkward
   nesting structures.
2) It directly exposes the tag so that it is convenient to write
   switches over the possible members.
3) It can re-use the same type for multiple tag values, something that
   has been worked around by either abusing PointerIntPair or defining
   nonce types and doing unsafe pointer casting.
4) It supports customization of the PointerLikeTypeTraits used for
   specific member types. This means it could (in theory) be used even
   with types that are over-aligned on allocation to expose larger
   numbers of bits to the tag.

All in all, I think it is at least complimentary to the existing
infrastructure, and a strict improvement for some use cases.

[Orc][RuntimeDyld] Prevent duplicate calls to finalizeMemory on shared memory

Prior to this patch, recursive finalization (where finalization of one
RuntimeDyld instance triggers finalization of another instance on which the
first depends) could trigger memory access failures: When the inner (dependent)
RuntimeDyld instance and its memory manager are finalized, memory allocated
(but not yet relocated) by the outer instance is locked, and relocation in the
outer instance fails with a memory access error.

This patch adds a latch to the RuntimeDyld::MemoryManager base class that is
checked by a new method: RuntimeDyld::finalizeWithMemoryManagerLocking, ensuring
that shared memory managers are only finalized by the outermost RuntimeDyld

This allows ORC clients to supply the same memory manager to multiple calls to
addModuleSet. In particular it enables the use of user-supplied memory managers
with the CompileOnDemandLayer which must reuse the supplied memory manager for
each function that is lazily compiled.

Philip Reames [Sat, 9 Jan 2016 01:31:13 +0000 (01:31 +0000)]
[rs4gc] Optionally directly relocated vector of pointers

This patch teaches rewrite-statepoints-for-gc to relocate vector-of-pointers directly rather than trying to split them. This builds on the recent lowering/IR changes to allow vector typed gc.relocates.

The motivation for this is that we recently found a bug in the vector splitting code where depending on visit order, a vector might not be relocated at some safepoint. Specifically, the bug is that the splitting code wasn't updating the side tables (live vector) of other safepoints. As a result, a vector which was live at two safepoints might not be updated at one of them. However, if you happened to visit safepoints in post order over the dominator tree, everything worked correctly. Weirdly, it turns out that post order is actually an incredibly common order to visit instructions in in practice. Frustratingly, I have not managed to write a test case which actually hits this. I can only reproduce it in large IR files produced by actual applications.

Rather than continue to make this code more complicated, we can remove all of the complexity by just representing the relocation of the entire vector natively in the IR.

At the moment, the new functionality is hidden behind a flag. To use this code, you need to pass "-rs4gc-split-vector-values=0". Once I have a chance to stress test with this option and get feedback from other users, my plan is to flip the default and remove the original splitting code. I would just remove it now, but given the rareness of the bug, I figured it was better to leave it in place until the new approach has been stress tested.
