From 75abf64287cab73546382a4fa7fa2f4e3516efeb Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Sat, 13 Jan 2018 19:32:43 -0600 Subject: parisc/signal: Add FPE_CONDTRAP for conditional trap handling Posix and common sense requires that SI_USER not be a signal specific si_code. Thus add a new FPE_CONDTRAP si_code for conditional traps.
