Most of our code was including Log.h even though that is not where the
"lldb" log channel is defined (Log.h defines the generic logging
infrastructure). This worked because Log.h included Logging.h, even
though it should.
After the recent refactor, it became impossible the two files include
each other in this direction (the opposite inclusion is needed), so this
patch removes the workaround that was put in place and cleans up all
files to include the right thing. It also renames the file to LLDBLog to
better reflect its purpose.
This reverts commit ef8206320769ad31422a803a0d6de6077fd231d2.
- It conflicts with the existing llvm::size in STLExtras, which will now
never be called.
- Calling it without llvm:: breaks C++17 compat
There is no reason why this function should be returning a ConstString.
While modifying these files, I also fixed several instances where
GetPluginName and GetPluginNameStatic were returning different strings.
I am not changing the return type of GetPluginNameStatic in this patch, as that
would necessitate additional changes, and this patch is big enough as it is.

This patch fixes:
llvm-project/lldb/source/Plugins/ABI/PowerPC/ABISysV_ppc.cpp:204:6:
error: missing field 'invalidate_regs' initializer
[-Werror,-Wmissing-field-initializers]
The previous version of the patch did not update the definitions in
conditionally compiled code. This patch includes changes to ARC and
windows targets.
Original commit message was:
These were added to support some mips registers on linux, but linux mips
support has now been removed due.
They are still referenced in the freebds mips implementation, but the
completeness of that implementation is also unknown. All other
architectures just set these fields to zero, which is a cause of
significant bloat in our register info definitions.
Arm also has registers with variable sizes, but they were implemented in
a more gdb-compatible fashion and don't use this feature.

This reverts commit 00e704bf080ffeeb9e334fb3ab71594f9aa50969.
This commit should should have updated
llvm/llvm-project/lldb/source/Plugins/ABI/ARC/ABISysV_arc.cpp like the other
architectures.

Remove redundant register alt_names that correspond to their respective
generic names. D108554 makes it possible to query registers through
their generic names directly, therefore making repeating them via
alt_name unnecessary.
While at it, also remove alt_names that are equal to register names
on PPC.
This patch does not alter register definitions where the generic names
are listed as primary names, and other names are provided as alt_name
(e.g. ARM).

In all these years, we haven't found a use for this function (it has
zero callers). Lets just remove the boilerplate.

Add a new state for UnwindPlan::Row which indicates that any
register not listed is not defined, and should not be found in
stack frames newer than this one and passed up the stack. Mostly
intended for use with architectural default unwind plans that are
used for jitted stack frames, where we have no unwind information
or start address. lldb has no way to tell if registers were
spilled in the jitted frame & overwritten, so passing register
values up the stack is not safe to show the user.
Architectural default unwind plans are also used as a fast unwind
plan on x86_64 in particular, and are used as the fallback unwind
plans when lldb thinks it may be able to work around a problem
which causes the unwinder to stop walking the stack early.
For fast unwind plans, when we don't find a register location in
the arch default unwind plan, we fall back to computing & using
the full unwind plan. One small part of this patch is to know that
a register marked as Undefined in the fast unwind plan is a special
case, and we should continue on to the full unwind plan to find what
the real unwind rule is for this register.

This patch has no effect for C and C++. In more dynamic languages,
such as Objective-C and Swift GetByteSize() needs to call into the
language runtime, so it's important to pass one in where possible. My
primary motivation for this is some work I'm doing on the Swift
branch, however, it looks like we are also seeing warnings in
Objective-C that this may resolve. Everything in the SymbolFile
hierarchy still passes in nullptrs, because we don't have an execution
context in SymbolFile, since SymbolFile transcends processes.

This is a step towards making the initialize and terminate calls be
generated by CMake, which in turn is towards making it possible to
disable plugins at configuration time.

Summary:
There's a fair amount of code duplication between the different ABI plugins for
the same architecture (e.g. ABIMacOSX_arm & ABISysV_arm). Deduplicating this
code is not very easy at the moment because there is no good place where to put
the common code.
Instead of creating more plugins, this patch reduces their number by grouping
similar plugins into a single folder/plugin. This makes it easy to extract
common code to a (e.g.) base class, which can then live in the same folder.
The grouping is done based on the underlying llvm target for that architecture,
because the plugins already require this for their operation.
