* Sprinkle a few __used markers to prevent gcc4 from throwing away essentialkettenis2010-05-019-40/+40
| | | | | | | bits of code and data. With this change gcc4 builds usable crt*.o on sparc64, other architectures probably need some more love. ok marco@, jsg@
* Use MACHINE_CPU instead of MACHINE_ARCH to pick the correct machine dependentmiod2010-02-031-3/+3
| | | | | | | files or directories when applicable. The inspiration and name of MACHINE_CPU come from NetBSD, although the way to provide it to Makefiles is completely different. ok kettenis@
* Make sure to use 64 bit instructions in the assembly statements (addi -> daddi)miod2009-12-101-8/+4
| | | | | in the prologue; this gives a chance for binaries loaded with their stack over 2GB virtual, to run. Who's your daddi now?
* rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andderaadt2009-10-2714-29/+23
| | | | | | | unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms

* 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
