Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)

- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

Introduction
This document covers the native NetBSD compiler runtime. The full support
for the native runtime is enabled by setting USE_COMPILERCRTSTUFF to no
in bsd.own.mk.
Machine independent sources can be found in common. The crtbegin.c in
that directory is a useful template for deriving compact assembler
versions. That is preferable to decouple the result from changes in the
compiler logic.
A new platform should provide the following content in
arch/${MACHINE_ARCH} or arch/${MACHINE_CPU}:
- Makefile.inc: provides ELFSIZE corresponding to 32/64bit file format.
If using the common C code instead of crtbegin.S also provide a -I option
to find crtbegin.h in your arch subdir.
- crt0.S: provides setup code and the call to ___start.
- crtbegin.S or crtbegin.h: see below
- crtend.S: see below, most likely just a copy of an existing architecture
- crti.S: prefix part of .init/.fini sections, i.e. to ensure stack alignment
- crtn.S: suffix part of the .init/.fini sections, i.e. return to caller.
Overview of the common runtime support
The common runtime support contains two modules, crtbegin and crtend.
@@ -61,3 +84,10 @@ Deinitialisation (called from .fini):
Call the pointers as void (*)(void) functions.
5. If __deregister_frame_info is NULL, return.
6. Call __deregister_frame_info with the start of .eh_frame as the argument.
Since most of this can easily be done in C code, instead of providing a
crtbegin.S you can also chose to use the generic C implementation. Provide
a crtbegin.h file instead of crtbegin.S. In there put inline assembler
stubs (mostly copied from some other arch) and implement calls to the
helper functions __do_global_ctors_aux/__do_global_dtors_aux.
