[VP] Explicitly map from VP intrinsic to ISD opcode

This patch aims to overcome an issue in these mappings where, when an ISD
node was registered with BEGIN_REGISTER_VP_SDNODE but outwidth the scope
of a pair of BEGIN_REGISTER_VP_INTRINSIC/END_REGISTER_VP_INTRINSIC
macros, the switch cases fell apart. This in particular happened with
VP_SETCC, where we'd end up with something along the lines of:

  case Intrinsic::vp_fcmp:
    break;
  case Intrinsic::vp_icmp:
    break;
    ResOpc = ISD::VP_SETCC;
  case Intrinsic::vp_store:
    ...

To remedy this, we introduce a special-purpose mapping macro which can
map any number of VP intrinsic opcodes to an ISD opcode.

As a result, we no longer need to special-case the mapping from vp.icmp

Kristóf Umann [Thu, 14 Oct 2021 12:30:58 +0000 (14:30 +0200)]
[analyzer] Don't track function calls as control dependencies

I recently evaluated ~150 of bug reports on open source projects relating to my
GSoC'19 project, which was about tracking control dependencies that were
relevant to a bug report.

Here is what I found: when the condition is a function call, the extra notes
were almost always unimportant, and often times intrusive:

void f(int *x) {
  x = nullptr;
  if (alwaysTrue()) // We don't need a whole lot of explanation
                    // here, the function name is good enough.
    *x = 5;
}
It almost always boiled down to a few "Returning null pointer, which participates
in a condition later", or similar notes. I struggled to find a single case
where the notes revealed anything interesting or some previously hidden
correlation, which is kind of the point of condition tracking.

This patch checks whether the condition is a function call, and if so, bails
out.

The argument against the patch is the popular feedback we hear from some of our
users, namely that they can never have too much information. I was specifically
fishing for examples that display best that my contribution did more good than
harm, so admittedly I set the bar high, and one can argue that there can be
non-trivial trickery inside functions, and function names may not be that
descriptive.

My argument for the patch is all those reports that got longer without any
notable improvement in the report intelligibility. I think the few exceptional
cases where this patch would remove notable information are an acceptable
sacrifice in favor of more reports being leaner.

The second case was producing a warning diagnostic that this was

In the third case we keep the current practice that this is accepted with a
warning (as an extension). The C++20 standard says it's an error.

We also ensure that using decls are only applied to items with external linkage.

It adds the functions
```

/// \param b The divisor represented by n words. Must be non-null.

/// \note The word order is in host endianness.

/// \note The storage of 'a' needs to hold n + 1 elements because some

[mlir] Add support for operation-produced successor arguments in BranchOpInterface

This patch revamps the BranchOpInterface a bit and allows a proper implementation of what was previously `getMutableSuccessorOperands` for operations, which internally produce arguments to some of the block arguments. A motivating example for this would be an invoke op with a error handling path:
```
invoke %function(%0)
  label ^success ^error(%1 : i32)

^error(%e: !error, %arg0 : i32):
  ...
```
The advantages of this are that any users of `BranchOpInterface` can still argue over remaining block argument operands (such as `%1` in the example above), as well as make use of the modifying capabilities to add more operands, erase an operand etc.

The way this patch implements that functionality is via a new class called `SuccessorOperands`, which is now returned by `getSuccessorOperands`. It basically contains an `unsigned` denoting how many operator produced operands exist, as well as a `MutableOperandRange`, which are the usual forwarded operands we are used to. The produced operands are assumed to the first few block arguments, followed by the forwarded operands afterwards. The role of `SuccessorOperands` is to provide various utility functions to modify and query the successor arguments from a `BranchOpInterface`.

[trace][intel pt] Create a common accessor for live and postmortem data

Some parts of the code have to distinguish between live and postmortem threads
to figure out how to get some data, e.g. thread trace buffers. This makes the
code less generic and more error prone. An example of that is that we have
two different decoders: LiveThreadDecoder and PostMortemThreadDecoder. They
exist because getting the trace bufer is different for each case.

The problem doesn't stop there. Soon we'll have even more kinds of data, like
the context switch trace, whose fetching will be different for live and post-
mortem processes.

As a way to fix this, I'm creating a common API for accessing thread data,
which is able to figure out how to handle the postmortem and live cases on

[lld-macho][nfc] Give non-text ConcatOutputSections order-independent finalization

This diff is motivated by my work to add proper DWARF unwind support. As
detailed in PR50956 functions that need DWARF unwind need to have
compact unwind entries synthesized for them. These CU entries encode an
offset within `__eh_frame` that points to the corresponding DWARF FDE.

In order to encode this offset during
`UnwindInfoSectionImpl::finalize()`, we need to first assign values to
`InputSection::outSecOff` for each `__eh_frame` subsection. But
`__eh_frame` is ordered after `__unwind_info` (according to ld64 at
least), which puts us in a bit of a bind: `outSecOff` gets assigned
during finalization, but `__eh_frame` is being finalized after
`__unwind_info`.

But it occurred to me that there's no real need for most
ConcatOutputSections to be finalized sequentially. It's only necessary
for text-containing ConcatOutputSections that may contain branch relocs
which may need thunks. ConcatOutputSections containing other types of
data can be finalized in any order.

This diff moves the finalization logic for non-text sections into a
separate `finalizeContents()` method. This method is called before
section address assignment & unwind info finalization takes place. In
theory we could call these `finalizeContents()` methods in parallel, but
in practice it seems to be faster to do it all on the main thread.

[Driver][NFC] Simplify handling of flags in Options.td

We aim at improving the readability and maintainability of Options.td,
and in particular its handling of 'Flags', by
 - limiting the extent of 'let Flags = [...] in {'s, and
 - adding closing comments to matching '}'s.
 - being more consistent about empty lines around 'let Flags' and '}'.

More concretely,
 - we do not let a 'let Flags' span across several headline comments.
   When all 'def's in two consecutive headlines share the same flags,
   we stil close and start a new 'let Flags' at the intermediate
   headline.
 - when a 'let Flags' span just one or two 'def's, set 'Flags' within
   the 'def's instead.
 - we remove nested 'let Flags'.

Note that nested 'let Flags' can be quite confusing, especially when
the outer was started long before the inner. Moving a 'def' out of the
inner 'let Flags' and setting 'Flags' within the 'def' will not have the
intended effect, as those flags will be overridden by the outer
'let Flags'.
