From 7ec70105dd24c40d5eb60c2f1199cc7e0c3a6cd2 Mon Sep 17 00:00:00 2001 From: Julian Brown Date: Thu, 2 Jun 2011 20:10:44 +0000 Subject: [PATCH] arm-cores.def (arm1156t2-s, [...]): Use v6t2 tuning. gcc/ * arm-cores.def (arm1156t2-s, arm1156t2f-s): Use v6t2 tuning. (cortex-a5, cortex-a8, cortex-a15, cortex-r4, cortex-r4f, cortex-m4) (cortex-m3, cortex-m1, cortex-m0): Use cortex tuning. * config/arm/arm-protos.h (tune_params): Add prefer_constant_pool field. * config/arm/arm.c (arm_slowmul_tune, arm_fastmul_tune) (arm_xscale_tune, arm_9e_tune, arm_cortex_a9_tune) (arm_fa726te_tune): Add prefer_constant_pool setting. (arm_v6t2_tune, arm_cortex_tune): New. * config/arm/arm.h (TARGET_USE_MOVT): Make dependent on prefer_constant_pool setting.
