POD value that classifies the properties of a section.

Synopsis

Declared in <llvm/MC/SectionKind.h>

class SectionKind;

Description

A section is classified into the deepest possible classification, and then the target maps them onto their sections based on what capabilities they have.

The comments below describe these as if they were an inheritance hierarchy in order to explain the predicates below.
