If Orig produces more than one value (rare) with different types (rarer) then
we need to make sure we check against the one that Orig actually represents,
not just the first type.
Unfortunately because of the combination of things that need to happen I wasn't
able to produce a test.
This is the first patch in an ongoing attempt of Include Cleaner: unused/missing
headere diagnostics, an IWYU-like functionality implementation for clangd. The
work is split into (mostly) distinct and parallelizable pieces:
- Finding all referenced locations (this patch).
- Finding all referenced locations of macros.
- Building IncludeGraph and marking headers as unused, used and directly used.
- Making use of the introduced library and add an option to use in clangd.

* Adding support for standard library headers (possibly through mapping
genfiles).

Add an implementation for the runtime functions related to SYSTEM_CLOCK.
As with CPU_TIME, this is based on std::clock(), which should be
available everywhere, but it is highly recommended to add
platform-specific implementations for systems where std::clock() behaves
poorly (e.g. POSIX).
The documentation for std::clock() doesn't specify a maximum value and
in fact wrap around behaviour is non-conforming. Therefore, this
implementation of SYSTEM_CLOCK is not guaranteed to wrap around either,
and after std::clock reaches its maximum value we will likely just
return failure rather than wrap around. If this happens often on your
system, please add a new platform-specific implementation.
We define COUNT_MAX as either the maximum value that can be stored in
a std::clock_t or in a 64-bit integer (whichever is smaller), and
COUNT_RATE as CLOCKS_PER_SEC. For POSIX systems, the value of
CLOCKS_PER_SEC is hardcoded to 10^6 and irrelevant for the values
returned by std::clock.

After some moment VS solution generated with LLVM_OPTIMIZED_TABLEGEN started to
generate all .inc files for each build. The reason was it had
"<path to native tablegen>/llvm-tblgen" without .exe as a dependency.

It looked more reasonable to set the wait state to
zero for all non-instructions. With that we can avoid
the special handling for them in `getWaitStatesSince`
and `AdvanceCycle`. This NFC patch makes the handling
more generic.
This change adds support to ORCv2 and the Orc runtime library for static
initializers, C++ static destructors, and exception handler registration for
ELF-based platforms, at present Linux and FreeBSD on x86_64. It is based on the
MachO platform and runtime support introduced in bb5f97e3ad.
Patch by Peter Housel. Thanks very much Peter!

When option `--symbolize` is true, llvm-xray convert will demangle function
name on default. This patch adds a llvm-xray convert option `no-demangle` to
determine whether to demangle function name when symbolizing function ids from

This patch extends the runtime unrolling infrastructure to support unrolling a loop with multiple exiting blocks branching to the same exit block used by the latch. It intentionally does not include a cost model change to enable this functionality unless appropriate force flags are used.
I decided to restrict this to the epilogue case. Given the changes ended up being pretty generic, we may be able to unblock the prolog case too, but I want to do that in a separate change to reduce the amount of code we all have to understand at one time.

This patch adds a breakpoints window that lists all breakpoints and
breakpoints locations. The window is implemented as a tree, where the
first level is the breakpoints and the second level is breakpoints
locations.
The tree delegate was hardcoded to only draw when there is a process,
which is not necessary for breakpoints, so the relevant logic was
abstracted in the TreeDelegateShouldDraw method.

This patch adds a new method SubSurface to the Surface class. The method
returns another surface that is a subset of this surface. This is
important to further abstract away drawing from the ncurses objects. For
instance, fields could previously be drawn on subpads only but can now
be drawn on any surface. This is needed to create the file search
dialogs and similar functionalities.
There is an opportunity to refactor window drawing in general using
surfaces, but we shall consider this separately later.

Reading modules first reads each control block in the chain and then all
AST blocks.
The first phase is intended to find recoverable errors, eg. an out of
date or missing module. If any error occurs during this phase, it is
safe to remove all modules in the chain as no references to them will
exist.
While reading the AST blocks, however, various fields in ASTReader are
updated with references to the module. Removing modules at this point
can cause dangling pointers which can be accessed later. These would be
otherwise harmless, eg. a binary search over `GlobalSLocEntryMap` may
access a failed module that could error, but shouldn't crash. Do not
remove modules in this phase, regardless of failures.
Since this is the case, it also doesn't make sense to return OutOfDate
during this phase, so remove the two cases where this happens.
When they were originally added these checks would return a failure when
the serialized and current path didn't match up. That was updated to an
OutOfDate as it was found to be hit when using VFS and overriding the
umbrella. Later on the path was changed to instead be the name as
written in the module file, resolved using the serialized base
directory. At this point the check is really only comparing the name of
the umbrella and only works for frameworks since those don't include
`Headers/` in the name (which means the resolved path will never exist)
Given all that, it seems safe to ignore this case entirely for now.
This makes the handling of an umbrella header/directory the same as
regular headers, which also don't check for differences in the path
caused by VFS.
