Improve performance of cgroup access (dotnet/coreclr#21229)

Currently, we create a CGroup instance on each request for getting
used or total physical memory. This has an extra cost of finding
filesystem paths of the current cgroup files. I have found that
if we do the initialization just once, the performance of getting
the used or total memory in a tight loop improves 22 times.

Accidentally, I was also looking into a perf regression in the
ByteMark.BenchBitOps test that was observed in the past, seemingly
related to the recent change to the way we get the used memory.
And I've found that the benchmark results improve two fold with
the change in this commit.

This change was made both in PAL and in the standalone GC.

JIT: handle general indir case for GT_JMP address

Some upcoming changes to reduce tiering overhead require that directly
invoked virtual methods be called indirectly via their slot, so that the
method body can be updated and callers patched up by patching the method
table slot.

Existing code for x64 implicitly assumes that a GT_JMP indirect target address
is near enough to the call site that a 32 bit RIP-relative displacement will
work. We can ensure this is true by always generating a reloc (and hence
potentially a jump stub) -- unless the target happens to fit in 32 bits and
so can be addressed absolutely.

JIT: retype some return expressions

The jit is fairly tolerant of byref/native int mismatches for inline arguments
and return values. And some of the new unsafe helpers do this kind of
reinterpretation across call boundaries as well. This sometimes leads the jit
to lose track of byrefs.

A general fix for this is likely somewhat involved. For now we simply detect if
we're about to lose track of a byref when substituting a particular kind of
return expression, and retype the expression to a byref.

Fixes dotnet/coreclr#21051.

5 years agoDon't assume objects don't escape in pure helpers.
Eugene Rozenfeld [Fri, 23 Nov 2018 22:55:02 +0000 (14:55 -0800)]
Don't assume objects don't escape in pure helpers.

We can't assume objects don't escape in helpers marked as pure for the following reasons:

1. The helpers may call user code that may make objects escape, e.g.,
https://github.com/dotnet/coreclr/blob/dotnet/coreclr@c94d8e68222d931d4bb1c4eb9a52b4b056e85f12/src/vm/jithelpers.cpp#L2371

2. The helpers usually protect gc pointers with GCPROTECT_BEGIN() so the pointers are reported as normal pointers to the gc.
Pointers to stack-allocated objects need to be reported as interior so they have to be protected with
GCPROTECT_BEGININTERIOR().

3. The helpers may cause these asserts in ValidateInner on stack-allocated objects:
https://github.com/dotnet/coreclr/blob/dotnet/coreclr@c94d8e68222d931d4bb1c4eb9a52b4b056e85f12/src/vm/object.cpp#L723

Eugene Rozenfeld [Mon, 19 Nov 2018 21:25:56 +0000 (13:25 -0800)]
Disable object stack allocation verification under GCStress.

ObjectStackAllocationTests use GC.GetAllocatedBytesForCurrentThread to
verify object stack allocations. Under GCStress the vm may initiate additional
heap allocations in GCHeap::StressHeap (see the call to 'pGenGCHeap->allocate' below).

This change re-enables ObjectStackAllocationTests and updates then to not verify stack allocations under GCStress.
It's useful to run the tests even without the verification to catch crashes, gc asserts, etc.
