Compiler-RT
================================
This directory and its subdirectories contain source code for the compiler
support routines.
Compiler-RT is open source software. You may freely distribute it under the
terms of the license agreement found in LICENSE.txt.
================================
This is a replacement library for libgcc. Each function is contained
in its own file. Each function has a corresponding unit test under
test/Unit.
A rudimentary script to test each file is in the file called
test/Unit/test.
Here is the specification for this library:

Assumptions are listed in "int_lib.h", and in individual files. Where possible
assumptions are checked at compile time.
