From 99e53b3b334866cdb5efc32fe983901d43c7d779 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sun, 28 Feb 2010 00:22:30 +0000 Subject: Generalize my hack to use SDNodeInfo to find out when a node is always guaranteed to have a particular type instead of hacking in ISD::STORE explicitly. This allows us to use implied types for a broad range of nodes, even target specific ones. llvm-svn: 97355 --- llvm/utils/TableGen/CodeGenDAGPatterns.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'llvm/utils/TableGen/CodeGenDAGPatterns.h') diff --git a/llvm/utils/TableGen/CodeGenDAGPatterns.h b/llvm/utils/TableGen/CodeGenDAGPatterns.h index c246483acff..60898bc04ce 100644 --- a/llvm/utils/TableGen/CodeGenDAGPatterns.h +++ b/llvm/utils/TableGen/CodeGenDAGPatterns.h @@ -125,6 +125,11 @@ public: return TypeConstraints; } + /// getKnownType - If the type constraints on this node imply a fixed type + /// (e.g. all stores return void, etc), then return it as an + /// MVT::SimpleValueType.
