Subject: [Bug middle-end/100604] GCC generates invalid LO_SYM for unaligned global
Date: Sat, 22 May 2021 16:21:52 +0000	[thread overview]
Message-ID: <bug-100604-4-kwI7e4JC3B@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #4 from dragan.mladjenovic at syrmia dot com ---
It seems to be copied from the owning var_decl align in
vararsm.c:assemble_variable. Now when optimizing that happens at a later stage
and rtx gets created lazily from var_decl and has only mode alignment. That's
why on -O or greater middle-end doesn't try to expand unaligned access, which
might be an issue in itself.
