Summary:
Currently, `cat` validates range selections before extracting the corresponding
source text. However, this means that any range inside a macro is rejected as an
error. This patch changes the implementation to first try to map the range to
something reasonable. This makes the behavior consistent with handling of ranges
used for selecting portions of the source to edit.
Also updates a clang-tidy lit-test for one of the checks which was affected by
this change.

The symbol map is a data structure for tracking variables in a subprogram during the lowering of that subprogram to FIR/MLIR. These data structures will be used by the bridge, which has not been upstreamed yet.

Use direct vector constants for the 1-D case. This approach
scales much better than generating elaborate insertion operations
that are eventually folded into a constant. We could of course
generalize the 1-D case to higher ranks, but this simplification
already helps in scaling some microbenchmarks that would formerly
crash on the intermediate IR length.

UBSan buildbot caught an undefined behavior in itostr with INT64_MIN.
The negation cannot be represented in the promoted operand (long long).
Negation is well defined on unsigned value though so this commit does

Summary:
Since commit 7b3ef05a37 the Objective-C++ plugin is dead code.
That commit added Objective-C++ to the list of languages for which `Language::LanguageIsCPlusPlus`
returns true. As the C++ language plugin also uses that method to figure out if it is responsible for a
given language, the C++ plugin since then also became the plugin that we found when looking for
a language plugin for Objective-C++. The only real fallout from that is that the source highlighting
for Objective-C++ files never worked as we always found the C++ plugin which refuses to highlight
files with Objective-C++ extensions.
This patch just adds a special exception for Objective-C++ to the list of languages that are governed
by the C++ plugin. Also adds a test that makes sure that we find the right plugin for all C language
types and that the highlighting for `.mm` (Objective-C++) and `.m` (Objective-C) files works.
I didn't revert 7b3ef05a37 as it does make sense to return
true for Objective-C++ from `Language::LanguageIsCPlusPlus` (e.g., we currently check if we care about
ODR violations by doing `if (Language::LanguageIsCPlusPlus(...))` and this should also work for
Objective-C++).

Summary:
TerminalSizeChanged is called from our SIGWINCH signal handler but the
IOHandlerEditline currently doesn't check if we are actually using the real
editline backend. If we're not using the real editline backend, `m_editline_up`
won't be set and `IOHandlerEditline::TerminalSizeChanged` will access
the empty unique_ptr. In a real use case we don't use the editline backend
when we for example read input from a file. We also create some temporary
IOHandlerEditline's during LLDB startup it seems that are also treated
as non-interactive (apparently to read startup commands).
This patch just adds a nullptr check for`m_editline_up` as we do in the rest of
IOHandlerEditline.

This relaxes an assertion that required symbols to start before the end
of a block. Instead, symbols are now required to end on or before the
end of a block. This fixes two important corner cases: Symbols at the
start of empty blocks/sections, and block/section end symbols.
and delete a bunch (but not all) redundant code. If you compare the remaining implementations of Platform*Simulator.cpp, there is still an obvious leftover cleanup task.
Specifically, this patch
- removes SDK initialization from dotest (there is equivalent but more
complete code in Makefile.rules)
- make Platform*Simulator inherit the generic implementation of
PlatformAppleSimulator (more can be done here)
- simplify the platform logic in Makefile.rules
- replace the custom SDK finding logic in Platform*Simulator with XcodeSDK
- adds a test for each supported simulator

If neither AT(lma) nor AT>lma_region is specified,
D76995 keeps `lmaOffset` (LMA - VMA) if the previous section is in the
default LMA region.
This patch additionally checks that the two sections are in the same
memory region.
Add a test case derived from https://bugs.llvm.org/show_bug.cgi?id=45313
.mdata : AT(0xfb01000) { *(.data); } > TCM
// It is odd to make .bss inherit lmaOffset, because the two sections
// are in different memory regions.
.bss : { *(.bss) } > DDR
With this patch, section VMA/LMA match GNU ld. Note, GNU ld supports
out-of-order (w.r.t sh_offset) sections and places .text and .bss in the
same PT_LOAD. We don't have that behavior.

Fixes PR46348.
ObjFile<ELFT>::initializeSymbols contains two symbol iteration loops:
```
for each symbol
if non-inheriting && non-local
fill in this->symbols[i]
for each symbol
if local
fill in this->symbols[i]
else
symbol resolution
```
Symbol resolution can trigger a duplicate symbol error which will call
InputSectionBase::getObjMsg to iterate over InputFile::symbols. If a
non-local symbol appears after the non-local symbol being resolved
(violating ELF spec), its `this->symbols[i]` entry has not been filled
in, InputSectionBase::getObjMsg will crash due to
`dyn_cast<Defined>(nullptr)`.
To fix the bug, reorganize the two loops to ensure this->symbols is
complete before symbol resolution. This enforces the invariant:
InputFile::symbols has none null entry when InputFile::getSymbols() is called.
```
for each symbol
if non-inheriting
fill in this->symbols[i]
for each symbol starting from firstGlobal
if non-local
symbol resolution
```
Additionally, move the (non-local symbol in local part of .symtab)
diagnostic from Writer<ELFT>::copyLocalSymbols() to initializeSymbols().

On AIX, we use __atexit to register dtor functions rather than __cxa_atexit.
So a driver change is needed to default AIX to using -fno-use-cxa-atexit.
Windows platform does not uses __cxa_atexit either. Following its precedent,
we remove the assertion for when -fuse-cxa-atexit is specified by the user,
do not produce a message and silently default to -fno-use-cxa-atexit behavior.

This patch adopts and reuses the `getGnuHashTableChains()` helper which performs

Also with this change we start to report a warning when the histogram is requested for
