Subject: [PATCH 1/2] Support get_range_query with a nullptr argument
Date: Fri, 17 Feb 2023 13:45:37 -0800 [thread overview]
Message-ID: <20230217214538.2177094-1-apinski@marvell.com> (raw)
get_range_query didn't support a nullptr argument
before and would crash.

https://inbox.sourceware.org/gcc/4f6718af-e17a-41ef-a886-f45e4ac3d7a4@redhat.com/T/
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
gcc/ChangeLog:
* value-query.h (get_range_query): Return the global ranges
for a nullptr func.
