+ Issue #6952
+
+ gcc/
+ * ira-costs.c (record_reg_classes): Ignore alternatives that are
+ not enabled.
+ * config/arm/vfp.md (arm_movdi_vfp): Enable only when not tuning
+ for Cortex-A8.
+ (arm_movdi_vfp_cortexa8): New pattern.
+ * config/arm/neon.md (adddi3_neon, subdi3_neon, anddi3_neon,
+ iordi3_neon, xordi3_neon): Add alternatives to discourage Neon
+ instructions when tuning for Cortex-A8. Set attribute "alt_tune".
+ * config/arm/arm.md (define_attr "alt_tune", define_attr "enabled"):
+ New.
