From 2d2959e85259dd49a2be7c708e845df36432aa3b Mon Sep 17 00:00:00 2001 From: Jeff Law Date: Fri, 12 May 1995 01:10:28 +0000 Subject: * Support debugging using native MACH primitives on hppa*-*-osf*. * configure.in: hppa*-*-osf* != hppa*-*-bsd* anymore. * config/pa/hppaosf.mh: New file. * config/pa/nm-hppao.h: Likewise. * hppam3-nat.c: Likewise. * config/pa/tm-hppao.h (PSW_SS): Define for single-stepping. (MACHINE_CPROC_*_OFFSET): Define. (TRACE_*): Define.
