Bug ID: 102967
Summary: -Waddress with nested structures: Incorrect "the
comparison will always evaluate as 'true'"
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: andrew.cooper3 at citrix dot com
Target Milestone: ---
Hello,
I have been compiling Xen with gcc/master, and found what appears to be a
regression from GCC 11.
https://godbolt.org/z/qa61fs1hK is a simplified repro.
The address comparison seems to be incorrectly applied to only of the two
possible options. The expression as a whole is most certainly not
unconditionally true.
