This prefix is used for globals like constant pool entries that are completely private to the ....

StringRef PrivateLabelPrefix

This prefix is used for labels for basic blocks.

bool HasDotTypeDotSizeDirective

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

This should be set to the directive used to get some number of zero (and non-zero if supported by the...

GOFF::EDAttr getEDAttributes() const

GOFF::EDAttr EDAttributes

MCSectionGOFF * getParent() const

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.

constexpr bool empty() const

empty - Check if the string is empty.

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.

#define llvm_unreachable(msg)

Marks that the current location is not supposed to be reachable.

@ ESD_ST_ElementDefinition

@ ESD_ST_SectionDefinition

This is an optimization pass for GlobalISel generic memory operations.
