From 24c56296258b3f282eca7981369b137cc1ed4bf1 Mon Sep 17 00:00:00 2001 From: Sjoerd Meijer Date: Wed, 29 May 2019 13:41:57 +0000 Subject: [PATCH] [ARM] Split predicates out into their own .td file The new ARMPredicates.td is included from ARM.td, early enough that the predicate definitions are already in scope when ARMSchedule.td is included. This will make it possible to refer to them in UnsupportedFeatures fields of scheduling models. NFC: the chunk of Tablegen being moved here is copied and pasted verbatim.
