And yet, we can look at this exactly as an example: if you set the CPU to long mode (a.k.a., 64-bit mode), then a LOT of previously obsolete instructions are dropped, especially those that were 1-byte opcodes. This is akin to what we're looking for here: if you opt in to greater and newer things, we can drop obsolete things you've had years (or decades, in the case of CPU) to port away from. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
