[Lldb-commits] [PATCH] D108078: [lldb] Support gdbserver signals [WIP]
mgorny updated this revision to Diff 366487.
mgorny edited the summary of this revision.
mgorny added a comment.
Added client tests for GDB and LLDB signal variants. Moved signal init into
`DidLaunchOrAttach`, in order to have normalized target triple already (needed
for correct os-name in test).

[Lldb-commits] [PATCH] D108088: [lldb] Avoid unhandled Error in TypeSystemMap::GetTypeSystemForLanguage
dim created this revision.
dim added reviewers: aprantl, emaste, JDevlieghere, teemperor.
Herald added subscribers: krytarowski, arichardson.
dim requested review of this revision.
Herald added a project: LLDB.
When assertions are turned off, the `llvm::Error` value created at the
start of this function is overwritten using the move-assignment
operator, but the success value is never checked. Whenever a TypeSystem
cannot be found or created, this can lead to lldb core dumping with:
Program aborted due to an unhandled Error:
Error value was Success. (Note: Success values must still be checked prior to
being destroyed).
Fix this by not creating a `llvm::Error` value in advance, and directly
returning the result of `llvm::make_error` instead, whenever an error is
encountered.
