The patch is for GCC 4.4, not earlier releases. There are plenty of features
in the rs6000 port that require newer versions of Binutils, but GCC probably
can work with older Binutils.
Alan, do you have any opinion about guarding the use of .hidden so that GCC
can work with older versions of Binutils?
Thanks, David

I wouldn't even try. Just add a note in doc/install.texi specifying
the minimum binutils version for targets affected by this change.
Incidentally, why do we still have crtsavres.asm? It looks like it should
have disappeared here:

Patch to doc/install.texi below, which I'll install as part of the
patch. It looks like Linux targets already required binutils 2.15,
which includes .hidden support. I just made it mandatory for all
PowerPC targets; I'm happy to lower it for PowerPC targets generally (to
pick up .hidden support) and still require 2.15 for Linux targets.
Gerald, is the patch OK? David/Alan, OK to require 2.15 for all PowerPC
targets?

Yup, silly me. I'll really delete it when I commit this patch.

I had thought you'd commit this based on David's response, but it
doesn't seem to have made it to SVN, so I figured I'd confirm this. ;-)

The patch below solves a problem related to the visibility of the
out-of-line prologue/epilogue functions. These functions are called by
the compiler at -Os; since they have non-standard calling conventions,
they are placed into static libgcc.a. However, they have default
visibility on ELF systems, which leads to the following failure mode:
gcc -Os -c -o libcode.o libcode.c
libcode.o now calls the out-of-line prologue/epilogue functions.
gcc -Os -shared -o libcode.so.1 -Wl,-soname,libcode.so.1
libcode.so.1 now exports the out-of-line prologue/epilogue functions.
gcc -Os -o myapp myapp.c -lcode
myapp calls the prologue/epilogue functions, but they are resolved to
the versions in the shared library instead of libgcc, which means they
get called through the PLT.
./myapp
Segmentation fault
When an prologue/epilogue function is called, the PLT resolver gets
invoked, which trashes r11...which the prologue/epilogue function
depended on, leading to bad results.
The fix, of course, is to make the prologue/epilogue functions hidden so
that when creating the shared library, they are not exported. Then when
myapp gets linked, the routines from libgcc.a are picked up rather than
the routines from the shared library.
I realize that doing this potentially breaks applications that were
using the symbol. However, if you were using the symbol, then things
were broken anyway. (FWIW, you could use LD_BIND_NOW to prevent this
from happening...but then the problem nor the fix will affect you
anyway.)
The patch is straightforward enough. Tested on powerpc-linux-gnuspe.
OK to commit?

Shouldn't libcode.o be compiled with -fPIC?

Many eons ago gas didn't support .hidden, do we still support such old
binutils and if yes, shouldn't you add .hidden only if HAVE_GAS_HIDDEN
is defined?

SH and Xtensa, at least, use .hidden unguarded by #if in some
configurations. So I suppose it's David's call as to whether he wants
to continue support for old (non-.hidden) binutils in the rs6000
backend. David?

In the Xtensa case that's understandable, as xtensa support has been added
to binutils more than 3 years after .hidden support (the latter 2000-01-03,
the former 2003-04-01).
