Hi all,This patch adds the attributes to arm.md that are used to control the conditions under which we can predicate an insn. We use the new attributes field for define_cond_exec that was defined in a recent patch. Whenever an insn is predicated through define_cond_exec, it has the attribute "predicated" set to "yes". The "enabled" definition is updated to take "predicated" and arm_restric_it into account to disable the predicated version when appropriate. Now, if we want to disable the predicated version of an alternative for arm_restrict_it we leave the "predicable" attribute as "yes" and set the "predicable_short_it" attribute to "no". The enabled_for_depr_it attribute is used to disable alternatives in some cases where explicit IT blocks are used in the output template. Ok for trunk? 2013-06-05 Kyrylo Tkachov <kyrylo.tkac...@arm.com> * config/arm/arm.md (enabled_for_depr_it): New attribute. (predicable_short_it): Likewise. (predicated): Likewise. (enabled): Handle above. (define_cond_exec): Set predicated attribute to yes.
OK. R.
