+ * gcc/config/rs6000/genfusion.pl (gen_ld_cmpi_p10): Improve generation
+ of the ld and lwa instructions which use the DS encoding instead of D.
+ Use the YZ constraint for these loads. Handle prefixed loads better.
+ Set the sign_extend attribute as appropriate.
+ * gcc/config/rs6000/fusion.md: Regenerate.
+ * gcc/config/rs6000/rs6000.md (prefixed attribute): Add fused_load_cmpi
+ instructions to the list of instructions that might have a prefixed load
+ instruction.
