From 93c89ab30835c0b518ea2d0c822edc74a68f192a Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 27 Oct 2000 14:30:52 -0700 Subject: [PATCH] alpha.h (enum reg_class): Add PV_REG. * config/alpha/alpha.h (enum reg_class): Add PV_REG. (REG_CLASS_NAMES, REG_CLASS_CONTENTS, REGNO_REG_CLASS): Update. (REG_CLASS_FROM_LETTER): Assign it to 'c'. * config/alpha/alpha.md (call_osf_1): Use it. (call_value_osf_1): Likewise.
