Subject: [PATCH v2 0/3] libgfortran: empty array fixes
Date: Tue, 7 Nov 2023 11:24:01 +0100 [thread overview]
Message-ID: <20231107102404.1723120-1-mikael@gcc.gnu.org> (raw)
Hello,
Harald's review of the previous version [1] of these patches spotted a possible
misbehaving case in one patch, and a latent bug in the area of the second
patch.
So here is the second try, bootstraped and regression tested on x86_64-pc-linux-gnu.
OK for master?
Mikael

Changes from version 1:
* Add patch 1/3 to the series fixing the unallocated empty result issue.
* In patch 2/3 (formerly 1/2) clamp negative extent to zero.
