virtual bool llvm::MCSection::isBaseAddressKnownZero ( ) const [inline, virtual]

isBaseAddressKnownZero - Return true if we know that this section will get a base address of zero. In cases where we know that this is true we can emit section offsets as direct references to avoid a subtraction from the base of the section, saving a relocation.

Reimplemented in llvm::MCSectionELF, and llvm::NVPTXSection.

Definition at line 64 of file MCSection.h.

Referenced by llvm::AsmPrinter::EmitSectionOffset().

virtual bool llvm::MCSection::isVirtualSection ( ) const [pure virtual]

isVirtualSection - Check whether this section is "virtual", that is has no actual object file contents.

Implemented in llvm::MCSectionMachO, llvm::MCSectionELF, llvm::MCSectionCOFF, and llvm::NVPTXSection.

Referenced by llvm::MachObjectWriter::getPaddingSize(), llvm::MCAsmLayout::getSectionFileSize(), llvm::MachObjectWriter::WriteObject(), llvm::MachObjectWriter::WriteSection(), and llvm::MCAssembler::writeSectionData().
