Targeting OS X 64 Bit
For the last several years, all Mac OS X machines include 64-bit CPUs, so the obvious next step is to target 64-bit code for OS X. A while back, I targeted the D programming language compiler to generate 32-bit code for OS X, and 64-bit code for Linux. Having a debugged and working 32-bit port to OS X, and a debugged and working 64-bit code generator, this should be... ) The object file format for OS X is the Mach-O, which is unique to OS X (the Linux universe uses the ELF format). The first step is to convince my dumpobj utility to recognize and dump the Mach-O 64 format. |

OpenSUSE 12.1 Proffers Polish and Performance
If you're new to GNOME 3, you'll find a help application available from the search tool once you have the system up and running. If you choose to install Btrfs as your default file system, you can take advantage of the new snapshot capability. The OpenSUSE installer had trouble deleting the existing LVM configuration on the primary hard drive. Installation If you take all the defaults during the installation process, you'll get a vanilla installation with a standard set of applications. Be aware that KDE is the default desktop, so if you click "Next" through all the option pages without changing anything, you'll wind up with a KDE-based system. For a full description of all the new features, check out the portal site for the 12. Snapper is the new system configuration tracker, which makes it possible to roll back to any previous snapshot if you're using Btrfs. |
Грубая настройка уровня оптимизации для GCC производится опцией -O. По умолчанию, если опция не указана Под оптимизацией обычно понимают достижение разумного компромиса между объёмом получаемого в результате компиляции объектного кода и совокупной скоростью выполнения программы....
