* Re-enable pie support on macppc (still off by default but usablekurt2009-01-142-12/+76
| | | | | | | | | | | | again). Due to the way executable sections are loaded by the kernel, a one page .got section with the blrl instruction may be in the data cache and not flushed causing random crashes upon process startup. Flush the data cache before ___start() jumps there. Also mprotect the .got section to be read/exec instead of read/write/exec. ld.so knows how to cope and static binaries don't write to .got. written by and okay drahn@

* Move landisk to hardware floating point. At the moment the FPU context ismiod2007-03-021-1/+9
| | | | | | | | | | | | | | | always saved upon context switches, as FPU registers are heavily used for long long computations (don't ask). Gcc default to -m4. Credits to drahn@ otto@ and deraadt@ for feedback and help testing. Upgrade procedure if you don't want to use the damn snapshots: - build and install new kernel, reboot off it - build new gcc, do not install it yet - make includes - install new gcc - build and install lib/csu and lib/libc - make build
