## Description
This pull request adds a new `stop-at-user-entry` option to LLDB
`process launch` command, allowing users to launch a process and pause
execution at the entry point of the program (for C-based languages,
`main` function).
## Motivation
This option provides a convenient way to begin debugging a program by
launching it and breaking at the desired entry point.
## Changes Made
- Added `stop-at-user-entry` option to `Options.td` and the
corresponding case in `CommandOptionsProcessLaunch.cpp` (short option is
'm')
- Implemented `GetUserEntryPointName` method in the Language plugins
available at the moment.
- Declared the `CreateBreakpointAtUserEntry` method in the Target API.
- Create Shell test for the command
`command-process-launch-user-entry.test`.
## Usage
`process launch --stop-at-user-entry` or `process launch -m` launches
the process and pauses execution at the entry point of the program.
This reverts commit a7b78cac9a.
With updates to the tests.
TestWatchTaggedAddress.py: Updated the expected watchpoint types,
though I'm not sure there should be a differnt default for the two
ways of setting them, that needs to be confirmed.
TestStepOverWatchpoint.py: Skipped this everywhere because I think
what used to happen is you couldn't put 2 watchpoints on the same
address (after alignment). I guess that this is now allowed because
modify watchpoints aren't accounted for, but likely should be.
Needs investigating.
Watchpoints in lldb can be either 'read', 'write', or 'read/write'. This
is exposing the actual behavior of hardware watchpoints. gdb has a
different behavior: a "write" type watchpoint only stops when the
watched memory region *changes*.
A user is using a watchpoint for one of three reasons:
1. Want to find what is changing/corrupting this memory.
2. Want to find what is writing to this memory.
3. Want to find what is reading from this memory.
I believe (1) is the most common use case for watchpoints, and it
currently can't be done in lldb -- the user needs to continue every time
the same value is written to the watched-memory manually. I think gdb's
behavior is the correct one. There are some use cases where a developer
wants to find every function that writes/reads to/from a memory region,
regardless of value, I want to still allow that functionality.
This is also a bit of groundwork for my large watchpoint support
proposal
https://discourse.llvm.org/t/rfc-large-watchpoint-support-in-lldb/72116
where I will be adding support for AArch64 MASK watchpoints which watch
power-of-2 memory regions. A user might ask to watch 24 bytes, and a
MASK watchpoint stub can do this with a 32-byte MASK watchpoint if it is
properly aligned. And we need to ignore writes to the final 8 bytes of
that watched region, and not show those hits to the user.
This patch adds a new 'modify' watchpoint type and it is the default.
Re-landing this patch after addressing testsuite failures found in CI on
Linux, Intel machines, and windows.

As suggested by Greg in https://github.com/llvm/llvm-project/pull/66534,
I'm adding a setting at the Target level that controls whether to show
leading zeroes in hex ValueObject values.
This has the benefit of reducing the amount of characters displayed in
certain interfaces, like VSCode.
The remaining use of ConstString in StructuredData is the Dictionary
class. Internally it's backed by a `std::map<ConstString, ObjectSP>`.
I propose that we replace it with a `llvm::StringMap<ObjectSP>`.
Many StructuredData::Dictionary objects are ephemeral and only exist for
a short amount of time. Many of these Dictionaries are only produced
once and are never used again. That leaves us with a lot of string data
in the ConstString StringPool that is sitting there never to be used
again. Even if the same string is used many times for keys of different
Dictionary objects, that is something we can measure and adjust for
instead of assuming that every key may be reused at some point in the
future.
Quick comparisons of key data is likely not a concern with Dictionary,
but the use of `llvm::StringMap` means that lookups should be fast with
its hashing strategy.
Switching to a llvm::StringMap meant that the iteration order may be
different. To account for this when serializing/dumping the dictionary,
I added some code to sort the output by key before emitting anything.

ConstString can be implicitly converted into a llvm::StringRef. This is
very useful in many places, but it also hides places where we are
creating a ConstString only to use it as a StringRef for the entire
lifespan of the ConstString object.
I locally removed the implicit conversion and found some of the places we
were doing this.

StreamFile subclasses Stream (from lldbUtility) and is backed by a File

The comment after the radar link already explains the issue. There's no
additional information in the radar and has been marked as closed by the
corresponding code change. This commit removes the link and reflows the
comment.
This is an enhancement for the locate module callback.
https://discourse.llvm.org/t/rfc-python-callback-for-target-get-module/71580/6
On Android remote platform, module UUID is resolved by
Platform::GetRemoteSharedModule. Which means the current
Target::CallLocateModuleCallbackIfSet() call undesirably is not able to pass the
module UUID to the locate module callback.
This diff moves the CallLocateModuleCallbackIfSet() implementation from Target
to Platform to allows both Target and Platform can call it. One is from the
current Target call site, and second is from Platform after resolving the module
UUID.
As the result of this change, the locate module callback may be called twice
for a same module on remote platforms. And it should be ok.
- First, without UUID.
- The locate module callback is allowed to return an error
if the callback requires UUID.
- Second, with UUID, if the first callback call did not return a module.

This patch add the ability for the user to set a label for a target.
This can be very useful when debugging targets with the same executables
in the same session.
Labels can be set either at the target creation in the command

Target labels show up in the `target list` output, following the target
index, and they also allow the user to switch targets using them.

Use templates to simplify {Get,Set}PropertyAtIndex. It has always

After this patch, SetPropertyAtIndex infers the type from its arguments
and GetPropertyAtIndex required a single template argument for the

Expression evaluation allocates memory for storing intermediate data during evaluation. For it to work properly it has to be allocated within target's available address space, for example within first 0xFFFF bytes for the 16-bit MSP430. The memory for such targets can be very tightly packed, but not all targets support GetMemoryRegionInfo API to pick an unused region, like MSP430 with MSPDebug GDB server.
These settings allow the programmer to manually pick precisely where and how much memory to allocate for expression evaluation in order not to overlap with existing data in process memory.

The majority of call sites are nullptr as the execution context.
Refactor OptionValueProperties to make the argument optional and
simplify all the callers.
Various OptionValue related classes are passing around will_modify but
the value is never used. This patch simplifies the interfaces by
removing the redundant argument.
Similar to fdbe7c7faa, refactor OptionValueProperties to return a
std::optional instead of taking a fail value. This allows the caller to
handle situations where there's no value, instead of being unable to
distinguish between the absence of a value and the value happening the
match the fail value. When a fail value is required,
std::optional::value_or() provides the same functionality.
This patch augments lldb's event listeners with a new shadow mode.
As the name suggests, this mode allows events to be copied to an
additional listener to perform event monitoring, without interferring
with the event life cycle.
One of our use case for this, is to be able to listen to public process
events while making sure the events will still be delivered to the
default process listener (the debugger listener in most cases).

This change ensures that the REPL map inside Target is destroyed correctly when `Target::Destroy()` is invoked. Not doing so results in the REPL not finishing its job when the debugger is initialized in REPL mode reading from a file.

This is a user facing action, it is meant to focus the user's attention on
something other than the 0th frame when you stop somewhere where that's
helpful. For instance, stopping in pthread_kill after an assert will select
the assert frame.
This is not something you want to have happen internally in lldb, both
because internally you really don't want the selected frame changing out
from under you, and because the recognizers can do arbitrary work, and that
can cause deadlocks or other unexpected behavior.
However, it's not something that the current code does
explicitly after a stop has been delivered, it's expected to happen implicitly
as part of stopping. I changing this to call SMRF explicitly after a user
stop, but that got pretty ugly quickly.
So I added a bool to control whether to run this and audited all the current
uses to determine whether we're returning to the user or not.

This patch should address an issue that caused the process public run
lock to not be updated during a process launch/attach when the process
stops.
That caused the public run lock to report its state as running while the
process state is stopped. This prevents the users to interact with the
process (through the command line or via the SBAPI) since it's
considered still running.
To address that, this patch refactors the name of the internal hijack
listeners to a specific pattern `lldb.internal.<action>.hijack` that
are used to ensure that we've attached to or launched a process successfully.
Then, when updating the process public state, after updating the state
value, if the process is not hijacked externally, meaning if the process
doens't have a hijack listener that matches the internal hijack
listeners pattern, we can update the public run lock accordingly.

This change uses the information from target.xml sent by
the GDB stub to produce C types that we can use to print
register fields.
lldb-server *does not* produce this information yet. This will
only work with GDB stubs that do. gdbserver or qemu
are 2 I know of. Testing is added that uses a mocked lldb-server.
```
(lldb) register read cpsr x0 fpcr fpsr x1
cpsr = 0x60001000
= (N = 0, Z = 1, C = 1, V = 0, TCO = 0, DIT = 0, UAO = 0, PAN = 0, SS = 0, IL = 0, SSBS = 1, BTYPE = 0, D = 0, A = 0, I = 0, F = 0, nRW = 0, EL = 0, SP = 0)
```
Only "register read" will display fields, and only when
we are not printing a register block.
For example, cpsr is a 32 bit register. Using the target's scratch type
system we construct a type:
```
struct __attribute__((__packed__)) cpsr {
uint32_t N : 1;
uint32_t Z : 1;
...
uint32_t EL : 2;
uint32_t SP : 1;
};
```
If this register had unallocated bits in it, those would
have been filled in by RegisterFlags as anonymous fields.
A new option "SetChildPrintingDecider" is added so we
can disable printing those.
Important things about this type:
* It is packed so that sizeof(struct cpsr) == sizeof(the real register).
(this will hold for all flags types we create)
* Each field has the same storage type, which is the same as the type
of the raw register value. This prevents fields being spilt over
into more storage units, as is allowed by most ABIs.
* Each bitfield size matches that of its register field.
* The most significant field is first.
The last point is required because the most significant bit (MSB)
being on the left/top of a print out matches what you'd expect to
see in an architecture manual. In addition, having lldb print a
different field order on big/little endian hosts is not acceptable.
As a consequence, if the target is little endian we have to
reverse the order of the fields in the value. The value of each field
remains the same. For example 0b01 doesn't become 0b10, it just shifts
up or down.
This is needed because clang's type system assumes that for a struct
like the one above, the least significant bit (LSB) will be first
for a little endian target. We need the MSB to be first.
Finally, if lldb's host is a different endian to the target we have
to byte swap the host endian value to match the endian of the target's
typesystem.
| Host Endian | Target Endian | Field Order Swap | Byte Order Swap |
|-------------|---------------|------------------|-----------------|
| Little | Little | Yes | No |
| Big | Little | Yes | Yes |
| Little | Big | No | Yes |
| Big | Big | No | No |
Testing was done as follows:
* Little -> Little
* LE AArch64 native debug.
* Big -> Little
* s390x lldb running under QEMU, connected to LE AArch64 target.
* Little -> Big
* LE AArch64 lldb connected to QEMU's GDB stub, which is running
an s390x program.
* Big -> Big
* s390x lldb running under QEMU, connected to another QEMU's GDB
stub, which is running an s390x program.
As we are not allowed to link core code to plugins directly,
I have added a new plugin RegisterTypeBuilder. There is one implementation
of this, RegisterTypeBuilderClang, which uses TypeSystemClang to build
the CompilerType from the register fields.

This patch adds process attach capabilities to the ScriptedProcess
plugin. This doesn't really expects a PID or process name, since the

In order to do so, this patch also turns the scripted process related
getters and setters from the `ProcessLaunchInfo` and
`ProcessAttachInfo` classes to a `ScriptedMetadata` instance and moves
it in the `ProcessInfo` class, so it can be accessed interchangeably.
This also adds the necessary SWIG wrappers to convert the internal
`Process{Attach,Launch}InfoSP` into a `SB{Attach,Launch}Info` to pass it
as argument the scripted process python implementation and convert it

lldb was originally designed to get the watchpoint exception behavior
from the gdb remote serial protocol stub -- exceptions are either
received before the instruction executes, or after the instruction
has executed. This behavior was reported via two lldb extensions
to gdb RSP, so generic remote stubs like gdbserver or a JTAG stub,
would not tell lldb which behavior was correct, and it would default
to "exceptions are received after the instruction has executed".
Two architectures hard coded their correct "exceptions before
instruction" behavior, to work around this issue.
Most architectures have a fixed behavior of watchpoint exceptions,
and we can center that information in lldb. We can allow a remote
stub to override the default behavior via our packet extensions
if it's needed on a specific target.
This patch also separates the fetching of the number of watchpoints
from whether exceptions are before/after the insn. Currently if
lldb couldn't fetch the number of watchpoints (not really needed), it
also wouldn't get when exceptions are received, and watchpoint
handling would fail. lldb doesn't actually use the number of
watchpoints for anything beyond printing it to the user.
