Introduction

The arch library is a repository for all architecture-dependent code. It isolates all platform dependencies (and confusing #ifdefs) into one small library and also serves as a common area for documentation of these multi-platform issues.

The high-level grouping of the classes/functions is:

• Bits

• Multithreading

• Math

• Strings

• System Functions

• Memory Management

• Diagnostics

• Symbol Visibility

Symbols for use within libarch:
