The latest GNU Compiler Collection code now has proper optimization targeting/tuning support for the IBM z13.

The z13 is IBM's new processor for their mainframes and claims to be the current fastest micro-processor in the world. The z13 has eight cores with a maximum frequency of 5GHz and is the latest design spin on the z/Architecture. For a while now, the Linux kernel has already well supported the z13 while GCC is just now receiving -march and -mtune support for the z13.

As of this commit from earlier this week, anyone running the latest GCC SVN/Git code and is lucky enough to have an IBM z13 mainframe can now utilize the -march=z13 and -mtune=z13 options for easily optimizing the generated code for the new IBM processors.
