------- 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)); \ \ } \ while (0) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41912
