From 6f03b636d26bebad3cfcaaa02a2bbc1b3a6c81b8 Mon Sep 17 00:00:00 2001 From: David Greene Date: Fri, 29 Jul 2011 19:07:18 +0000 Subject: [PATCH] [AVX] Make UnOpInit Unique Make sure UnOpInits are unique and created only once. This will be important for AVX/SIMD as many operators will be used to generate patterns and other relevant data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136494 91177308-0d34-0410-b5e6-96231b3b80d8 --- utils/TableGen/Record.cpp | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/utils/TableGen/Record.cpp b/utils/TableGen/Record.cpp index 4608d7aa149..8fc0c18cd4b 100644 --- a/utils/TableGen/Record.cpp +++ b/utils/TableGen/Record.cpp @@ -714,7 +714,16 @@ const Init *OpInit::resolveListElementReference(Record &R, const RecordVal *IRV, } const UnOpInit *UnOpInit::get(UnaryOp opc, const Init *lhs, RecTy *Type) { - return new UnOpInit(opc, lhs, Type); + typedef std::pair, RecTy *> Key; + + typedef DenseMap Pool; + static Pool ThePool; + + Key TheKey(std::make_pair(std::make_pair(opc, lhs), Type)); + + UnOpInit *&I = ThePool[TheKey]; + if (!I) I = new UnOpInit(opc, lhs, Type); + return I; } const Init *UnOpInit::Fold(Record *CurRec, MultiClass *CurMultiClass) const { -- 2.34.1
