Changes
…lly registered languages
First of all, this is done to support exceptions for the Mojo language, but
it's done in a way that will benefit any other plugin language.
1. I added a new lldb-dap CLI argument (not DAP field) called
`pre-init-commands`. These commands are executed before DAP initialization. The
other `init-commands` are executed after DAP initialization. It's worth
mentioning that the debug adapter returns to VSCode the list of supported
exception breakpoints during DAP initialization, which means that I need to
register the Mojo plugin before that initialization step, hence the need for
`pre-init-commands`. In general, language plugins should be registered in that
step, as they affect the capabilities of the debugger.
2. I added a set of APIs for lldb-dap to query information of each language
related to exception breakpoints. E.g. whether a language supports throw or
catch breakpoints, how the throw keyword is called in each particular language,
etc.
3. I'm realizing that the Swift support for exception breakpoints in lldb-dap
should have been implemented in this way, instead of hardcoding it.

I see why this doesn't work now. LLDB plugins are added to the `LLDB_PLUGINS`
global property via the PLUGIN argument to `add_lldb_library`. You aren't
adding the PLUGIN argument to the `add_lldb_library` invocation in
`lldb/source/Plugins/ScriptInterpreter/Python/Interfaces/CMakeLists.txt`. This
is how the build system knows the list of plugins.
But even if you were to remove this and add that `PLUGIN` argument, this still
wouldn't work. I don't think we've explicitly documented this behavior, but
LLDB expects each library to be one plugin, not three as you've done here. When
LLDB creates a plugin, it's going to generate a `Plugins.def` file that LLDB
uses to initialize and teardown all plugins. It has a list of entries that look
like this:
`LLDB_PLUGIN(lldbPluginFooBar)`. There are some exceptions for the script
interpreter plugins (not sure why, didn't check). It also expects the
`LLDB_PLUGIN_DEFINE` argument to match the library name exactly (without the
initial `lldbPlugin`, specifically).
The way I see it, you have three options:
1. Restructure the build so that there are 3 libraries, each one of them a
plugin.
2. Change LLDB's CMake machinery to accept libraries that define multiple
plugin interfaces. You'll need to modify `add_lldb_library` so that you can
pass it a list of plugin interface names instead of assuming the plugin names
matches the library's name.
3. Keep the workaround and document why it exists.
I would suggest (1) or (2). I think (3) is just kicking the can down the road.
This is a solution that explicitly works around LLDB's existing plugin system,
is difficult to discover without knowing its there, and could make future
refactors more difficult.

https://github.com/jeffreytan81 requested changes to this pull request. One concern is that, whether minidump format specification supports multiple exception streams. If this is not supported by spec, we may generate minidump that only lldb can read/parse but can fail other consumers. It would be interesting to copy the generated minidump with multiple exception steams to a Windows machine and try windbg/Visual Studio and see if they break. https://github.com/llvm/llvm-project/pull/97470 ___ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits

LOG: [lldb-dap][NFC] Minor rename
As a minor follow up for https://github.com/llvm/llvm-project/pull/97675, I'm
renaming `SupportsExceptionBreakpoints` to
`SupportsExceptionBreakpointsOnThrow` and adding a
`SupportsExceptionBreakpointsOnCatch` to have a bit of more granularity.

Previously this took a reference to a map and returned a bool
to say whether it succeeded. This is an optional but with more
steps.
The only reason to keep it that way was if someone was appending
to an existing map, but all callers made a new map before calling

`contains` will only check if the key exists in the map, but you want to
actually get the `bool` if it exists and default to `false` if it doesn't. I
think `lookup` fits better.

DavidSpickett wrote:
The caller creating a blank map to pass to this function is the symptom of what
I'm looking to fix here. The implementations are still going to create a map if
they're going to return features.
The motivation for the change is to allow:
```
if (auto features = sys::getCPUHostFeatures())
```
Instead of:
```
map features;
if (sys::getCPUHostFeatures(map)
```
As the optional better describes the situation. You either get a feature map or
you don't. Versus bool+mutable ref which could allow any combination of states.
The docstring helps but might as well use the typesystem to say the same thing
as well.
If the callers were building a map as they went, I'd understand the mutable ref
parameter. Like:
```
map features
if (add_some_features(features))
if (add_some_more_features(features))
filter_features(features)
```
But all uses create an empty map specifically to pass to the function.
...which is to say yeah, I should include the motivation in the commit message,
let me do that :)

IIUC, the motivation is to avoid creating a blank map. But here we still create
it with each call. Is there any difference except early return in line 1728,
which should rarely happend.

Changes
Previously this took a reference to a map and returned a bool to say whether it
succeeded. This is an optional but with more steps.
The only reason to keep it that way was if someone was appending to an existing
map, but all callers made a new map before calling it.

github-actions[bot] wrote: @kiyolee Congratulations on having your first Pull Request (PR) merged into the LLVM Project! Your changes will be combined with recent changes from other authors, then tested by our [build bots](https://lab.llvm.org/buildbot/). If there is a problem with a build, you may receive a report in an email or a comment on this PR. Please check whether problems have been caused by your change specifically, as the builds can include changes from many authors. It is not uncommon for your change to be included in a build that fails due to someone else's changes, or infrastructure issues. How to do this, and the rest of the post-merge process, is covered in detail [here](https://llvm.org/docs/MyFirstTypoFix.html#myfirsttypofix-issues-after-landing-your-pr). If your change does cause a problem, it may be reverted, or you can revert it yourself. This is a normal part of [LLVM development](https://llvm.org/docs/DeveloperPolicy.html#patch-reversion-policy). You can fix your changes and open a new PR to merge them again. If you don't get any reports, no action is required from you. Your changes are working as expected, well done! https://github.com/llvm/llvm-project/pull/97796 ___ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits

If you wish to, you can add reviewers by using the "Reviewers" section on this page. If this is not working for you, it is probably because you do not have write permissions for the repository. In which case you can instead tag reviewers by name in a comment by using `@` followed by their GitHub username. If you have received no comments on your PR for a week, you can request a review by "ping"ing the PR by adding a comment “Ping”. The common courtesy "ping" rate is once a week.
