From f9bbcd1afd24110b4b90f31779d95b16c58e2f69 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Wed, 5 Aug 2009 01:29:28 +0000 Subject: Major calling convention code refactoring. Instead of awkwardly encoding calling-convention information with ISD::CALL, ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering provides three virtual functions for targets to override: LowerFormalArguments, LowerCall, and LowerRet, which replace the custom lowering done on the special nodes. They provide the same information, but in a more immediately usable format. This also reworks much of the target-independent tail call logic. The decision of whether or not to perform a tail call is now cleanly split between target-independent portions, and the target dependent portion in IsEligibleForTailCallOptimization. This also synchronizes all in-tree targets, to help enable future refactoring and feature work. llvm-svn: 78142 --- llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp') diff --git a/llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp b/llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp index 335c73c..58a09276 100644 --- a/llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp +++ b/llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp @@ -20,8 +20,8 @@ // type i8 which must be promoted. // // This does not legalize vector manipulations like ISD::BUILD_VECTOR, -// or operations that happen to take a vector which are custom-lowered like -// ISD::CALL; the legalization for such operations never produces nodes +// or operations that happen to take a vector which are custom-lowered; +// the legalization for such operations never produces nodes // with illegal types, so it's okay to put off legalizing them until // SelectionDAG::Legalize runs. // -- cgit v1.1
