[PATCH] Fixup PPC symbol versioning for libgcc symbols

[Franz Sirl]

Hi,

phew, this was hard, but after finding my way thru a maze of binutils bugs and 
misinformations, here is finally a patch that does what we want on PPC, 
namely not to export any libgcc symbols from glibc with linktime reference, 
yet keeping the backwards compatibility with shared libs compiled against a 
pre-.hidden libgcc. I've attached patches for mainline and 2-2, both tested 
with gcc-2.95.4 and gcc-3.[12]. I also rebuilt loads of packages against it 
without problems.

When building gcc-3 against a fixed glibc, binutils-2.13.90.0.4 or later is 
needed, otherwise libgcc_s may contain unversioned symbols. I will add a 
platform statement to the gcc instructions soon.

Uli, sorry for the number iterations on this issue, but I was new to symbol 
versioning...

Thanks to HJ for fixing all these binutils oddities!

Franz.


	* sysdeps/powerpc/Makefile: Add HAVE_DOT_HIDDEN to CPPFLAGS for
	divdi3.c and libgcc-compat.S.
	* sysdeps/powerpc/libgcc-compat.c: Delete, optimize to ...
	* sysdeps/powerpc/libgcc-compat.S: New file.
	* sysdeps/powerpc/divdi3.c: New file, version and hide symbols of the generic
	version.
	* sysdeps/powerpc/Versions: Add forgotten symbols.
