Remove redundand declarations from xmalloc.c, which are already present in rtld.h. Reviewed by: kan Discussed with: bde MFC after: 2 weeks
* Rtld links with the specially built pic static libc library to get somekib2011-08-241-5/+11
| | | | | | | | | | | | | | | | | C runtime services, like printf(). Unfortunately, the multithread-safeness measures in the libc do not work in rtld environment. Rip the kernel printf() implementation and use it in the rtld instead of libc version. This printf does not require any shared global data and thus is mt-safe. Systematically use rtld_printf() and related functions, remove the calls to err(3). Note that stdio is still pulled from libc due to libmap implementaion using fopen(). This is safe but unoptimal, and can be changed later. Reported and tested by: pgj Diagnosed and reviewed by: kan (previous version) Approved by: re (bz)

quite a few enhancements and bug fixes. There are still some known deficiencies, but it should be adequate to get us started with ELF. Submitted by: John Polstra <jdp@polstra.com>
