This class is intended to be used as a base class for asm properties and features specific to the tar...
Definition: MCAsmInfo.h:56
Context object for machine code objects.
Definition: MCContext.h:76
Base class for the full range of assembler expressions which are needed for parsing.

Definition: MCSectionGOFF.h:46
bool isVirtualSection() const override
Check whether this section is "virtual", that is has no actual object file contents.

bool useCodeAlign() const override
Return true if a .align directive should use "optimized nops" to fill instead of 0s.

SectionKind - This is a simple POD value that classifies the properties of a section.
Definition: SectionKind.h:22
StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50
Triple - Helper class for working with autoconf configuration names.
Definition: Triple.h:44
This class implements an extremely fast bulk output stream that can only output to a stream.
Definition: raw_ostream.h:52
This is an optimization pass for GlobalISel generic memory operations.
