Subject: [Bug ada/41912] FAIL: gnat.dg/null_pointer_deref1.adb execution test
Date: Fri, 04 Dec 2009 09:58:00 -0000 [thread overview]
Message-ID: <20091204095803.13386.qmail@sourceware.org> (raw)
In-Reply-To: <bug-41912-276@http.gcc.gnu.org/bugzilla/>
------- Comment #11 from ebotcazou at gcc dot gnu dot org 2009-12-04 09:58 -------
> Very likely because of the adjustment made in libjava/pa-signal.h:
libjava/hppa-signal contains a slight variant:
#define MAKE_THROW_FRAME(_exception) \
do \
{ \
ucontext_t *_context = (ucontext_t *) arg; \
(void)_dummy; \
(void)_info; \
mcontext_t *mc = &(_context->uc_mcontext); \
SetSSReg (mc, ss_pcoq_head, GetSSReg (mc, ss_pcoq_tail)); \
SetSSReg (mc, ss_pcsq_head, GetSSReg (mc, ss_pcsq_tail)); \
/* This part is not quit right if the head pc was pointing \
at a branch. The tail needs to be adjusted to the branch \
target if the branch is taken. The tail space register \
may need adjustment as well if the branch is an interspace \
branch. */ \
SetSSReg (mc, ss_pcoq_tail, (GetSSReg (mc, ss_pcoq_tail) + 4)); \
\
} \
