7 years agoFix perf regression with lots of objects in a ConditionalWeakTable
Stephen Toub [Wed, 7 Dec 2016 21:35:03 +0000 (16:35 -0500)]
Fix perf regression with lots of objects in a ConditionalWeakTable

The CoreRT implementation of ConditionalWeakTable that was ported back to CoreCLR uses a special scheme to make reads lock-free.  When the container needs to grow, it allocates new arrays and duplicates all of the dependency handles from the previous array, rather than just copying them.  This avoids issues stemming from a thread getting a dependency handle in an operation on the container, then having that handle destroyed, and then trying to use it; the handle won't be destroyed as long as the container is referenced.

However, this also leads to a significant cost in a certain situation.  Every time the container grows, it allocates another N dependency handles where N is the current size of the container.  So, for example, with an initial size of 8, if 64 objects are added to the container, it'll allocate 8 dependency handles, then another 16, then another 32, and then another 64, resulting in significantly more handles than in the old implementation, which would only allocate 64 handles total.

This commit fixes that by changing the scheme slightly.  A container still frees its handles in its finalizer.  However, rather than duplicating all handles, that responsibility for freeing is transferred from one container to the next.  Then to avoid issues where, for example, the second container is released while the first is still in use, a reference is maintained from the first to the second, so that the second can't be finalized while the first is still in use.

The commit also fixes a race condition with resurrection and finalization, whereby dependency handles could be used while or after they're being freed by the finalizer. It's addressed by only freeing handles in a second finalization after clearing out state in the first finalization to guarantee no possible usage during the second.

Disable special put args for LIMIT_CALLER on x86.

On x86, `LSRA_LIMIT_CALLER` is too restrictive to allow the use of special

ecx, and edx--of which the latter two are also used for the first two
integral arguments to a call. This can leave us with too few registers to

only `eax` and `edx`. The allocator will then fail to allocate a register

ref position will be constrained to { `ecx`, `ebx`, `esi`, `edi` }, which
`LSRA_LIMIT_CALLER` will further constrain to `ecx`, which will not be
available due to the special put arg.

fgMorphCall may change a call to the stelem.ref helper that is storing a
null value into a simple store. This transformation needs to construct a
comma tree to hold the argument setup nodes present on the call if any
exist. Originally this tree was constructed in right-leaning fashion
(i.e. the first comma node was the root of the tree and each successive
comma node was the RHS of its parent). Unfortunately, this construction
did not automatically propagate the flags of a comma node's children to
the comma node, since not all of each comma node's actual children were
available at the time it was constructed. Constructing the tree in
left-leaning fashion (i.e. the first comma node is the left-most child
and the final comma node is the root of the tree) allows the flag
propagation to be performed correctly by constrution.

Change ArraySortHelper to use Comparison<T>

The Array/List.Sort overloads that take a Comparison<T> have worse performance than the ones that take a IComparer<T>. That's because sorting is implemented around IComparer<T> and a Comparison<T> needs to be wrapped in a comparer object to be used.

At the same time, interface calls are slower than delegate calls so the existing implementation doesn't offer the best performance even when the IComparer<T> based overloads are used.
