"There's a bug in the SH asm, it calls into 'C' code without preserving
all the important scratch registers. I have been meaning to double
check the changes as I think more registers need to be saved, then I
was going to send it back to uClibc. From the sound of it this isn't
your problem, but you never know.
Attached is the patch as it stands for the loader on SH."
Glibc appears to do the same.

the SuperH lib loader can be compiled by GCC 3.3

how uClibc handles _init and _fini, allowing shared lib constructors and
destructors to initialize things in the correct sequence. Stefan ported the SH
architecture. I then ported x86, arm, and mips. x86 and arm are working fine,
but I don't think I quite got things correct for mips.

shared library support. This also adds some cleaner error
handling, which I (Erik) then ported over to x86 and arm.
In addition Stefan added the following fixes:
- in hash.c was the lvalue handling of global library functions wrong.
To fix this I had to change the prototype of _dl_find_hash. (==> TIS and
ELF spec. Vers. 1.2)
- in ldso.c was the order of the .init sections calls wrong. Before we call
the initialization code of a library we have to check that all dependend
libraries are already initialized. This can easily made by calling it in the
revers loading order. For this I added a previous pointer chain.
- in ldso.c the ELF magics wasn't checked fo PPC, MIPS and SH architecture
