From 7c2924367087caa738d1c6349d04a4645c6c26fa Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Sat, 20 Jan 2007 23:32:04 +0000 Subject: Implement a getTypeSizeInBits method. This helps in transforms that want to ensure the bit size of a type is identical before proceeding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33413 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Target/TargetData.h | 4 ++++ lib/Target/TargetData.cpp | 10 ++++++++++ 2 files changed, 14 insertions(+) diff --git a/include/llvm/Target/TargetData.h b/include/llvm/Target/TargetData.h index b045bef..71db27c 100644 --- a/include/llvm/Target/TargetData.h +++ b/include/llvm/Target/TargetData.h @@ -221,6 +221,10 @@ public: /// uint64_t getTypeSize(const Type *Ty) const; + /// getTypeSizeInBits - Return the number of bytes necessary to hold the + /// specified type. + uint64_t getTypeSizeInBits(const Type* Ty) const; + /// getTypeAlignmentABI - Return the minimum ABI-required alignment for the /// specified type. unsigned char getTypeAlignmentABI(const Type *Ty) const; diff --git a/lib/Target/TargetData.cpp b/lib/Target/TargetData.cpp index 3cfdd40..f50e6c3 100644 --- a/lib/Target/TargetData.cpp +++ b/lib/Target/TargetData.cpp @@ -426,6 +426,16 @@ uint64_t TargetData::getTypeSize(const Type *Ty) const { return Size; } +uint64_t TargetData::getTypeSizeInBits(const Type *Ty) const { + if (Ty->isInteger()) + return cast(Ty)->getBitWidth(); + + uint64_t Size; + unsigned char Align; + getTypeInfoABI(Ty, this, Size, Align); + return Size * 8; +} + unsigned char TargetData::getTypeAlignmentABI(const Type *Ty) const { uint64_t Size; unsigned char Align; -- cgit v1.1
