Subject: pgsql: Further reduce dependence on -fwrapv semantics in jsonb.
Date: Fri, 16 Aug 2024 20:07:15 +0000
Message-ID: <E1sf3EB-0001jj-OZ@gemulon.postgresql.org> (raw)
Further reduce dependence on -fwrapv semantics in jsonb.
Commit 108d2adb9e missed updating a few places in the jsonb code
that rely on signed integer wrapping for correctness. These can
also be fixed by using pg_abs_s32() to negate a signed integer
(that is known to be negative) for comparison with an unsigned
integer.
