bool NeedsDwarfSectionOffsetDirective

MCSymbolAttr ProtectedVisibilityAttr

This attribute, if not MCSA_Invalid, is used to declare a symbol as having protected visibility.

bool HasCOFFComdatConstants

True if this is a non-GNU COFF target.

const char * WeakRefDirective

This directive, if non-null, is used to declare a global as being a weak undefined symbol.

bool HasDotTypeDotSizeDirective

True if the target has .type and .size directives, this is true for most ELF targets.

bool HasCOFFAssociativeComdats

True if this is a non-GNU COFF target.

bool SupportsDebugInformation

True if target supports emission of debugging information.

MCSymbolAttr HiddenDeclarationVisibilityAttr

This attribute, if not MCSA_Invalid, is used to declare an undefined symbol as having hidden visibili...

bool HasSingleParameterDotFile

True if the target has a single parameter .file directive, this is true for ELF targets.

bool COMMDirectiveAlignmentIsInBytes

True is .comm's and .lcomms optional alignment is to be specified in bytes instead of log2(n).

MCSymbolAttr HiddenVisibilityAttr

This attribute, if not MCSA_Invalid, is used to declare a symbol as having hidden visibility.

This represents a section on Windows.

bool shouldOmitSectionDirective(StringRef Name) const

Decides whether a '.section' directive should be printed before the section name.

void setSelection(int Selection) const

Definition MCAsmInfoCOFF.cpp:89

Instances of this class represent a uniqued identifier for a section in the current translation unit.

StringRef getName() const

StringRef - Represent a constant reference to a string, i.e.

Triple - Helper class for working with autoconf configuration names.

This class implements an extremely fast bulk output stream that can only output to a stream.
