◆ getExplicitSectionGlobal()

MCSection * llvm::NVPTXTargetObjectFile::getExplicitSectionGlobal ( const GlobalObject GO,
SectionKind  Kind,
const TargetMachine TM 
) const

Targets should implement this method to assign a section to globals with an explicit section specfied.

The implementation of this method can assume that GO->hasSection() is true.

Implements llvm::TargetLoweringObjectFile.

◆ getSectionForConstant()

MCSection * llvm::NVPTXTargetObjectFile::getSectionForConstant ( const DataLayout DL,
SectionKind  Kind,
const Constant C,
Align Alignment 
) const

Given a constant with the SectionKind, return a section that it should be placed in.

Given a mergable constant with the specified size and relocation information, return a section that it should be placed in.

Reimplemented from llvm::TargetLoweringObjectFile.
