[Lldb-commits] [PATCH] D63054: [lldb] [Process/NetBSD] Fix error handling in register operations

[Michał Górny via Phabricator via lldb-commits]

Ensure that errors are passed through correctly when performing
register read/write operations.  Currently, any ptrace() errors are
silently discarded and LLDB behaves as if operation was successful.

// NB: This is a prerequisite for xstate support since xstate might not be supported on old kernels and ptrace() will fail then.
