Subject: [PATCH v3 9/9] gdb: remove psymtab.{c,h}
Date: Fri, 27 Feb 2026 22:51:56 -0500 [thread overview]
Message-ID: <20260228035425.422765-10-simon.marchi@efficios.com> (raw)
In-Reply-To: <20260228035425.422765-1-simon.marchi@efficios.com>
From: Simon Marchi <simon.marchi@polymtl.ca>
The last user of psymtabs has been changed not to use them, remove them.
Update the tests minimally to avoid introducing failures (mostly due to
tests using the removed maintenance commands). There are still a lot of
references to partial symtabs in the comments or test names. There are
probably some tests that are just not relevant anymore. It would be quite
difficult to do this job all at once, we can clean this up little by
little.
Update the docs to remove references to partial symbols/symtabs.
Mention the removal of the maintenance commands in NEWS.
