--- Comment #5 from Siddhesh Poyarekar <siddhesh at gcc dot gnu.org> --- (In reply to Martin Liška from comment #4) > Note the libQt6 version of the function looking approximately like this: > This doesn't warn anymore (and doesn't crash either) because objsz cannot get past the bit_and_expr: gimple_assign <plus_expr, _11, data.0_10, 7, NULL> gimple_assign <bit_and_expr, _12, _11, 18446744073709551612, NULL> gimple_assign <nop_expr, start_13, _12, NULL, NULL> gimple_call <__builtin_object_size, _2, start_13, 1> However, ISTM from the remaining IR that thanks to the casts, it will see the right size if it got past the bit_and_expr. Jakub, should we recognize bit_and_expr in objsz for gcc13?
