The C and C++ Libraries

4.1.1 Build options and library variants

When you build your application, you must make certain fundamental choices. For

example:

Byte order Big-endian or little-endian.

Floating-point support

FPA, VFP, software, or none.

Stack limit Checked or unchecked.

Position-independence

Data can be read/write position-independent or not position-independent.

Code can be read-only position-independent or not position-independent.

When you link your assembly language, C, or C++ code, the linker selects appropriate

C and C++ library variants compatible with the build options you specified. There is a

variant of the ANSI C library for each combination of major build options. Build

options are described in more detail in:

• the ATPCS chapter in the ADS Developer Guide

• the libraries chapter in the ADS Linker and Utilities Guide

• Procedure Call Standard options on page 2-12 for the compiler

• the ADS Assembler Guide for the assembler.
