18-* The RPC implementation in libc is obsoleted. Old programs keep working
19- but new programs cannot be linked with the routines in libc anymore.
20- Programs in need of RPC functionality must be linked against TI-RPC.
21- The TI-RPC implementation is IPv6 enabled and there are other benefits.
22-
23- Visible changes of this change include (obviously) the inability to link
24- programs using RPC functions without referencing the TI-RPC library and the
25- removal of the RPC headers from the glibc headers.
26- Implemented by Ulrich Drepper.

28 * New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at,

1Upstream-Status: Inappropriate [embedded specific]
2
3The default lib search path order is:
4
5 1) LD_LIBRARY_PATH
6 2) RPATH from the binary
7 3) ld.so.cache
8 4) default search paths embedded in the linker
9
10For nativesdk binaries which are being used alongside binaries on a host system, we
11need the search paths to firstly search the shipped nativesdk libs but then also
12cover the host system. For example we want the host system's libGL and this may be
13in a non-standard location like /usr/lib/mesa. The only place the location is know
14about is in the ld.so.cache of the host system.
15
16Since nativesdk has a simple structure and doesn't need to use a cache itself, we
17repurpose the cache for use as a last resort in finding host system binaries. This
18means we need to switch the order of 3 and 4 above to make this work effectively.

2On mips target, binutils currently sets DT_MIPS_RLD_MAP to 0 in dynamic
