If the types don't match, we can't just remove the shuffle.

Fangrui Song 513d3658e7 [PPC64] Consider localentry offset when computing branch distance
Summary:
We don't take localentry offset into account, and thus may fail to
create a long branch when the gap is just a few bytes smaller than 2^25.

relocation R_PPC64_REL24 out of range: 33554432 is not in [-33554432, 33554431]
relocation R_PPC64_REL24 out of range: 33554436 is not in [-33554432, 33554431]

Fix that by adding the offset to the symbol VA.

```
Assertion failed: (isa<X>(Val) && "cast<Ty>() argument of incompatible type!"), function cast
```
so replace them with `dyn_cast`.

Pavel Labath f96b6d9270 Kill modify-python-lldb.py
Summary:
After the last round of cleanups, this script was almost a no-op. The
only piece of functionality that remained was the one which tried to
make the swig-generated function signatures more pythonic.

The "tried" part is important here, as it wasn't doing a really good job
and the end result was not valid python nor c (e.g.,
SetExecutable(SBAttachInfo self, str const * path)).

Doing these transformations another way is not possible, as these
signatures are generated by swig, and not present in source. However,
given that this is the only reason why we need a swig post-process step,
and that the current implementation is pretty sub-optimal, this patch
simply abandons the signature fixup idea, and chooses to simplify our
build process instead.

Nico Weber ccf096463a Let llvm-cvtres (and lld-link) report duplicate resources
If two .res files contain the same resource, cvtres.exe (and hence
link.exe) reject the input with this message:

    CVTRES : fatal error CVT1100: duplicate resource.  type:STRING, name:101, language:0x0409
    LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt

llvm-cvtres (and lld-link) used to silently pick one of the duplicate
resources instead. This patch makes them report an error as well.
We slightly improve on cvtres by printing the name of two .res files
containing duplicate entries as well.

Pavel Labath 88813103cd PostfixExpression: move parser out of NativePDB internals
Summary:
The postfix expressions in PDB and breakpad symbol files are similar
enough that they can be parsed by the same parser. This patch
generalizes the parser in the NativePDB plugin and moves it into the
PostfixExpression file created in the previous commit (r358976).

The generalization consists of treating any unrecognised token as a
"symbol" node (previously these would only be created for tokens
starting with "$", and other token would abort the parse). This is
needed because breakpad symbols can also contain ".cfa" tokens, which
refer to the frame's CFA.

The cosmetic changes include:
- using a factory function instead of a class for creating nodes (this
  is more generic as it allows the same BumpPtrAllocator to be used for
  other things too)
- using dedicated function for parsing operator tokens instead of a
  DenseMap (more efficient as we don't need to create the DenseMap every
  time).

Bjorn Pettersson 71e8c6f20f Add "const" in GetUnderlyingObjects. NFC
Summary:
Both the input Value pointer and the returned Value
pointers in GetUnderlyingObjects are now declared as
const.

It turned out that all current (in-tree) uses of
GetUnderlyingObjects were trivial to update, being
satisfied with have those Value pointers declared
as const. Actually, in the past several of the users
had to use const_cast, just because of ValueTracking
not providing a version of GetUnderlyingObjects with
"const" Value pointers. With this patch we get rid
of those const casts.

Craig Topper 1e413ffa7b [Mips][CodeGen] Remove MachineFunction::setSubtarget. Change Mips to just copy the subtarget from the MachineFunction instead of recalculating it.
Summary:
The MachineFunction should have been created with the correct subtarget. As
long as there is no way to change it, MipsTargetMachine can just capture it
directly from the MachineFunction without calling getSubtargetImpl again.

While there, const correct the Subtarget pointer to avoid a const_cast.

I believe the Mips16Subtarget and NoMips16Subtarget members are never used, but
I'll leave there removal for a separate patch.

Eric Fiselier add16a8da9 [Builtins] Implement __builtin_is_constant_evaluated for use in C++2a
Summary:
This patch implements `__builtin_is_constant_evaluated` as specifier by [P0595R2](https://wg21.link/p0595r2). It is built on the back of Bill Wendling's work for `__builtin_constant_p()`.

More tests to come, but early feedback is appreciated.

I plan to implement warnings for common mis-usages like those belowe in a following patch:
```
void foo(int x) {
  if constexpr (std::is_constant_evaluated())) { // condition is always `true`. Should use plain `if` instead.
   foo_constexpr(x);
  } else {
    foo_runtime(x);
  }
}
```

Eric Fiselier 70ebeabfb8 Rewrite cxa guard implementation.
This patch does three main things:
  (1) It re-writes the cxa guard implementation to make it testable.
  (2) Adds support for recursive init detection on non-apple platforms.
  (3) It adds a futex based implementation.

The futex based implementation locks and notifies on a per-object basis, unlike the
current implementation which uses a global lock for all objects. Once this patch settles
I'll turn it on by default when supported.

Richard Smith 0b098754b7 Fix interactions between __builtin_constant_p and constexpr to match
current trunk GCC.

GCC permits information from outside the operand of
__builtin_constant_p (but in the same constant evaluation context) to be
used within that operand; clang now does so too. A few other minor
deviations from GCC's behavior showed up in my testing and are also
fixed (matching GCC):
 * Clang now supports nullptr_t as the argument type for
   __builtin_constant_p
 * Clang now returns true from __builtin_constant_p if called with a
   null pointer
 * Clang now returns true from __builtin_constant_p if called with an
   integer cast to pointer type

                Line: 6, Column: 0 }
  - String:   ' because its definition is unavailable'
...
```

to:

```
--- !Missed
Pass: 0
Name: 1
DebugLoc: { File: 3, Line: 7, Column: 3 }
Function: 2
Args:
  - Callee:   4
  - String:   5
  - Caller:   2
    DebugLoc: { File: 3, Line: 6, Column: 0 }
  - String:   6

```

And the string table in the .remarks/__remarks section containing:

```
inline\0NoDefinition\0printArgsNoRet\0
test-suite/SingleSource/UnitTests/2002-04-17-PrintfChar.c\0printf\0
will not be inlined into \0 because its definition is unavailable\0
```

This is mostly supposed to be used for testing purposes, but it gives us
a 2x reduction in the remark size, and is an incremental change for the
updates to the remarks file format.
