ReachingDefInfo InstSet & ToRemove

This file declares classes for handling the YAML representation of DWARF Debug Info.

ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory),...

Lightweight error class with error context and mandatory checking.

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

bool starts_with(StringRef Prefix) const

Check if this string starts with the given Prefix.

Saves strings in the provided stable storage and returns a StringRef with a stable character pointer.

An efficient, type-erasing, non-owning reference to a callable.

SectionType

These are the section type and attributes fields.

@ S_GB_ZEROFILL

S_GB_ZEROFILL - Zero fill on demand section (that can be larger than 4 gigabytes).

@ S_THREAD_LOCAL_ZEROFILL

S_THREAD_LOCAL_ZEROFILL - Thread local zerofill section.

@ S_ZEROFILL

S_ZEROFILL - Zero fill on demand section.

This is an optimization pass for GlobalISel generic memory operations.
