This directory contains the C and C++ runtime libraries for the LLVM GCC
front-ends. It is composed of four distinct pieces:
1. __main: now dead, but provided for compatibility.
2. Generic EH support routines. This is used by C/C++ programs that use
setjmp/longjmp, and by C++ programs that make use of exceptions.
3. setjmp/longjmp EH support. This is used by C/C++ programs that call SJLJ.
4. C++ exception handling runtime support.
These four components are compiled together into an archive file, so that
applications using a subset of the four do not pull in unnecessary code and
dependencies.
