Subject: 	* partial-stab.h (N_TEXT): Put back GDB_TARGET_IS_HPPA kludge,
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=866ed2b54f6873610b155dfbd97ee1f42300d7cf;p=binutils-gdb.git

	* partial-stab.h (N_TEXT): Put back GDB_TARGET_IS_HPPA kludge,
	it is still needed for GCC-2.6 compiled code.
	* TODO (GDB_TARGET_IS_HPPA): Note this kludge can be nuked
	sometime after GCC-2.7 has been released.

 	retrieving the PC from a signal handler caller.  Fix thinko
 	in Stan's last change ("frame", should have been "frame->next").
