From 03e32fb74897185119352fa2340782b6d7510024 Mon Sep 17 00:00:00 2001 From: Jeff Law Date: Wed, 27 Jun 2018 12:30:06 -0600 Subject: [PATCH] v850-modes.def (CCZ, CCNZ): Add new modes. * config/v850/v850-modes.def (CCZ, CCNZ): Add new modes. * config/v850/v850.c (notice_update_cc): Remove. * config/v850/v850.h (CC_OVERFLOW_UNUSABLE): Remove (CC_NO_CARRY): Likewise. (NOTICE_UPDATE_CC): Define to nothing. * config/v850/v850.md: Remove block comment on cc0 handling Remove "cc" attribute from all patterns. Remove cc_status handling from all patterns. Minor formatting fixes.
