Definition DWARFDebugFrame.h:224

Lightweight error class with error context and mandatory checking.

MCRegisterInfo base class - We assume that the target defines a static array of MCRegisterDesc object...

SmallString - A SmallString is just a SmallVector with methods and accessors that make it work better...

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

Represent a sequence of Call Frame Information instructions that, when read in order,...
