[lldb] Add the ability to remove diagnostic callbacks

2023-02-09T21:20:51+00:00

Add the ability to remove diagnostic callbacks. This is necessary for
diagnostics who's lifetime is tied to objects that can be destroyed.

[lldb] Use std::optional instead of llvm::Optional (NFC)

2023-01-07T22:18:35+00:00

This patch replaces (llvm::|)Optional< with std::optional<.  I'll post
a separate patch to clean up the "using" declarations, #include
"llvm/ADT/Optional.h", etc.

This is part of an effort to migrate from llvm::Optional to
std::optional:

[lldb] Add #include (NFC)

2023-01-07T21:43:00+00:00

This patch adds #include  to those files containing
llvm::Optional<...> or Optional<...>.

I'll post a separate patch to actually replace llvm::Optional with
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

[lldb] Emit diagnostic events in the diagnostic dump

2022-10-31T21:40:41+00:00

Connect the diagnostic events with the diagnostic infrastructure.

 - Emit existing diagnostic events (warnings and errors) to the
   diagnostic log.
 - Introduce a new diagnostic event (info) that's used exclusively for
   diagnostic logging and does not get broadcast.

[lldb] Add a "diagnostics dump" command

2022-10-31T21:40:41+00:00

Add a "diagnostics dump" command to, as the name implies, dump the
diagnostics to disk. The goal of this command is to let the user
generate the diagnostics in case of an issue that doesn't cause the
debugger to crash.

This command is also critical for testing, where we don't want to cause
a crash to emit the diagnostics.

[lldb] Add diagnostics

2022-10-31T21:40:38+00:00

Around this time last year, I said on the mailing list [1] that I wanted
to to transform the reproducers into something that resembles a
sysdiagnose on Apple platforms: a collection of files containing a
variety of information to help diagnose bugs or troubleshoot issues.

This patch adds that framework. Based on lessons learned from the
reproducers, I've intentionally tried to keep it small and simple.
Different parts of LLDB can register callbacks (this is necessary for
layering purposes) that will get called when the diagnostics should be
generated.
