[X86] X86DAGToDAGISel::matchBitExtract(): extract 'lshr' from `X`

Summary:
As discussed in previous review, and noted in the FIXME, if `X` is actually an `lshr Y, Z` (logical!),
we can fold the `Z` into 'control`, and let the `BEXTR` do this too.
We could just insert those 8 bits of shift amount into control,
but it is better to instead zero-extend them, and 'or' them in place.

We can only do this for `lshr`, not `ashr`, because we do not know that the mask cover only the bits of `Y`,
and not any of the sign-extended bits.

The obvious question is, is this actually legal to do?
I believe it is. Relevant quotes, from `Intel® 64 and IA-32 Architectures Software Developer’s Manual`, `BEXTR — Bit Field Extract`:
* `Bit 7:0 of the second source operand specifies the starting bit position of bit extraction.`
* `A START value exceeding the operand size will not extract any bits from the second source operand.`
* `Only bit positions up to (OperandSize -1) of the first source operand are extracted.`
* `All higher order bits in the destination operand (starting at bit position LENGTH) are zeroed.`
* `The destination register is cleared if no bits are extracted.`

FIXME: if we can do this, i wonder if we should prefer `BEXTR` over `BZHI` in such cases.

re-used the PDB_SymType enumeration for this.  For native pdb support,

specifically, is in the globals stream / public stream / module stream /
TPI stream / etc, and for whichever one it is in, where is it within
that stream?

that it is more or less impossible to create a uid for a field list
member of a class/struction/union/enum that tells you how to locate
the original record.

this record lives.  This gives us much better flexibility in

Sanjay Patel [Thu, 15 Nov 2018 14:53:37 +0000 (14:53 +0000)]
[InstSimplify] delete shift-of-zero guard ops around funnel shifts

This is a problem seen in common rotate idioms as noted in:
https://bugs.llvm.org/show_bug.cgi?id=34924

Note that we are not canonicalizing standard IR (shifts and logic) to the intrinsics yet.
(Although I've written this before...) I think this is the last step before we enable
that transform. Ie, we could regress code by doing that transform without this
simplification in place.

In PR34924, I questioned whether this is a valid transform for target-independent IR,
but I convinced myself this is ok. If we're speculating a funnel shift by turning cmp+br
into select, then SimplifyCFG has already determined that the transform is justified.
It's possible that SimplifyCFG is not taking into account profile or other metadata,
but if that's true, then it's a bug independent of funnel shifts.

Also, we do have CGP code to restore a guard like this around an intrinsic if it can't
be lowered cheaply. But that isn't necessary for funnel shift because the default
expansion in SelectionDAGBuilder includes this same cmp+select.

5 years agoStart adding the supporting code to perform out-of-process allocator
Dan Liew [Thu, 15 Nov 2018 14:20:28 +0000 (14:20 +0000)]
Start adding the supporting code to perform out-of-process allocator
enumeration.

Summary:

This patch introduces the local portion (`LocalAddressSpaceView`) of the
`AddressSpaceView` abstraction and modifies the secondary allocator
so that the `ForEachChunk()` method (and its callees) would work in the
out-of-process case when `AddressSpaceView` is `RemoteAddressSpaceView`.

The `AddressSpaceView` abstraction simply maps pointers from a target
process to a pointer in the local process (via its `Load()` method). For
the local (in-process) case this is a no-op. For the remote
(out-of-process) case this is not a no-op. The implementation of the
out-of-process `RemoteAddressSpaceView` is not included in this patch
and will be introduced later.

This patch is considerably simpler than the `ObjectView` abstraction
used in previous patches but lacks the type safety and stricter memory
management of the `ObjectView` abstraction.

This patch does not introduce any tests because with
`LocalAddressSpaceView` it should be a non functional change and unit
tests already cover the secondary allocator.  When
`RemoteAddressSpaceView` is landed tests will be added to ensure that it
functions as expected.
