* hppa-tdep.c (frame_saved_pc): Mask off low two bits when
retrieving the PC from a signal handler caller. Fix thinko

mask, value, start address. ADB searches until it finds it or hits
an error (or is interrupted).
The GDB_TARGET_IS_HPPA kludges in partial-stab.h should be zapped sometime
after GCC-2.7 has been released (whenever we decide corner case debugging
problems with GCC-2.6 compiled code are not important).

In a nutshell, we need a way to determine when we've hit
the end of a file with debug symbols. Most ports do this
with a N_SO record with a NULL symbol name (as will GCC 2.7
on the PA). GCC 2.6 (and earlier) on the PA instead creates
an N_TEXT symbol with the name "end_file." */
