--- Comment #7 from Alexander Monakov <amonakov at gcc dot gnu.org> --- In comment #2 I touched upon a potentially more practical way to offer -fno-strict-alignment: Run early work with ABI alignments: compute __alignof correctly, lay out composite types as required by ABI, and assign alignments to variables (including stack variables and function parameters). Then make a pass over types and reduce their alignment. This way, optimizations see a universe where types have alignment 1, and variables are defined as if they had an explicit attribute-align with increased alignment (and likewise for structure fields).
