David E. O'Brien a6d80351b7 Re-initialize gp after a jsr.
When rtld runs the .fini section in a shared lib (C++), the code in
question from .../contrib/gdb/config/alpha/crtbegin.asm first calls
__do_globals_dtors_aux and then __do_frame_takedown.  Unfortunately, the
value of gp after a jsr is undefined and in this case had changed from before
the call, probably as a result of calling code in some other shared library.
The normal calling convention for alpha is to re-initialize gp using
'ldgp gp,0(ra)' after a jsr instruction but in this case no such
re-initialization is done. This leads to a bogus value being read for the
address of __do_frame_takedown and a quick segfault.

This directory contains the GNU Compiler Collection (GCC) version 2.95.
It includes all of the support for compiling C, C++, Objective C, Fortran,
Java, and Chill.

The GNU Compiler Collection is free software.  See the file COPYING for copying
permission.

See the file gcc.texi (together with other files that it includes) for
installation and porting information.  The file INSTALL contains a
copy of the installation information, as plain ASCII.

Installing this package will create various files in subdirectories of
/usr/local/lib, which are passes used by the compiler and a library
named libgcc.a.  It will also create /usr/local/bin/gcc, which is
the user-level command to do a compilation.

See the Bugs chapter of the GCC Manual for how to report bugs
usefully.  An online readable version of the manual is in the files
gcc.info*.

The files pself.c and pself1.c are not part of GCC.
They are programs that print themselves on standard output.
They were written by Dario Dariol and Giovanni Cozzi, and are
included for your hacking pleasure.  Likewise pself2.c
(Who is the author of that?) and pself3.c (by Vlad Taeerov and Rashit
Fakhreyev).
