Bug ID: 88583
Summary: -Wpacked-not-aligned shouldn't be in -Wall
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: andi-gcc at firstfloor dot org
Target Milestone: ---
gcc 9 added -Wpacked-not-aligned to Wall. In Linux kernel builds this warning
is very noisy. There's a Linux kernel patch now to disable it. But I suspect
other software using packed will be affected too.
It's especially pointless on x86 where unaligned only matters in some special
cases (with vectors)
When the programmer specified packed they should know what they are doing.
