5 gcc/
6 * ira-costs.c (record_reg_classes): Ignore alternatives that are
7 not enabled.
8 * config/arm/vfp.md (arm_movdi_vfp): Enable only when not tuning
9 for Cortex-A8.
10 (arm_movdi_vfp_cortexa8): New pattern.
11 * config/arm/neon.md (adddi3_neon, subdi3_neon, anddi3_neon,
12 iordi3_neon, xordi3_neon): Add alternatives to discourage Neon
13 instructions when tuning for Cortex-A8. Set attribute "alt_tune".
14 * config/arm/arm.md (define_attr "alt_tune", define_attr "enabled"):
15 New.
