[PATCH][ARM][1/3] Add rev field to rtx cost tables

2014-03-19 Thread Kyrill Tkachov

Hi all, In order to properly cost the rev16 instruction we need a new field in the cost tables. This patch adds that and specifies its value for the existing cost tables. Since rev16 is used to implement the BSWAP operation we add handling of that in the rtx cost function using the new field.
