Reid Kleckner 6bf108d77a [COFF] Use COFF stubs for extern_weak functions
Summary:
A COFF stub indirects the reference to a symbol through memory. A
.refptr.$sym global variable pointer is created to refer to $sym.
Typically mingw uses these for external global variable declarations,
but we can use them for weak function declarations as well.

Updates the dso_local classification to add a special case for
extern_weak symbols on COFF in both clang and LLVM.

Fixes PR37598

This patch allows the hazard recognizer to consider bundled instructions in both scheduler and hazard recognizer mode. We ignore “bundledness” for the purpose of detecting hazards and examine the instructions individually.

Lang Hames 2b09b25e48 [JITLink] Add support for MachO .alt_entry atoms.
The MachO .alt_entry directive is applied to a symbol to indicate that it is
locked (in terms of address layout and liveness) to its predecessor atom. I.e.
it is an alternate entry point, at a fixed offset, for the previous atom.

This patch updates MachOAtomGraphBuilder to check for the .alt_entry flag on
symbols and add a corresponding LayoutNext edge to the atom-graph. It also
updates MachOAtomGraphBuilder_x86_64 to generalize handling of the
X86_64_RELOC_SUBTRACTOR relocation: previously either the minuend or
subtrahend of the subtraction had to be the same as the atom being fixed up,
now it is only necessary for the minuend or subtrahend to be locked (via any
chain of alt_entry directives) to the atom being fixed up.

Jonas Devlieghere fe608c938c Revert "[OpenMP][Clang] Support for target math functions"
This commit appears to be breaking stage-2 builds on GreenDragon. The
OpenMP wrappers for cmath and math.h are copied into the root of the
resource directory and cause a cyclic dependency in module 'Darwin':
Darwin -> std -> Darwin. This blows up when CMake is testing for modules
support and breaks all stage 2 module builds, including the ThinLTO bot
and all LLDB bots.

Robert Lougher 8681ef8f41 [InstCombine] Add new combine to add folding
(X | C1) + C2 --> (X | C1) ^ C1 iff (C1 == -C2)

I verified the correctness using Alive:
https://rise4fun.com/Alive/YNV

This transform enables the following transform that already exists in
instcombine:

(X | Y) ^ Y --> X & ~Y

As a result, the full expected transform is:

(X | C1) + C2 --> X & ~C1 iff (C1 == -C2)

There already exists the transform in the sub case:

(X | Y) - Y --> X & ~Y

However this does not trigger in the case where Y is constant due to an earlier
transform:

X - (-C) --> X + C

With this new add fold, both the add and sub constant cases are handled.

Fundamentally/generally, we should not have to rely on bailouts/crippling of

Adrian Prantl e6e8db5e9b Debug Info: Support address space attributes on rvalue references.
DWARF5, 2.12 20ff says that

Any debugging information entry representing a pointer or reference

The existing code (https://reviews.llvm.org/D29670) seems to take a
quite literal interpretation of that wording. I don't see a reason why
an rvalue reference isn't a reference type in the spirit of that
paragraph. This patch allows rvalue references to also have address
spaces.

Pavel Labath 0ff89dacaf PostfixExpression: Use signed integers in IntegerNode
Summary:
This is necessary to support parsing expressions like ".cfa -16 + ^", as
that format is used in breakpad STACK CFI expressions.

Since the PDB expressions use the same parser, this change will affect
them too, but I don't believe that should be a problem in practice. If
PDBs do contain the negative values, it's very likely that they are
intended to be parsed the same way, and if they don't, then it doesn't
matter.

In case that we do ever need to handle this differently, we can always
make the parser behavior customizable, or just use a different parser.

To make sure that the integer size is big enough for everyone, I switch
from using a (unsigned) 32-bit integer to a 64-bit (signed) one.
