The library filename identifies how the variant was built.
Normally, you do not have to list any of the C and C++ libraries explicitly on the linker command line. The ARM linker automatically selects the correct C or C++ libraries to use, and it might use several, based on the accumulation of the object attributes.
The values for the fields of the filename, and the relevant build options are:
ARM C library. The
arm_linux subdirectory contains libraries used for building ARM
C++ library for ARM.
Libraries used when building ARM Linux applications.
ISO C and C++ basic runtime support.
Rogue Wave C++ library.
ARM C++ runtime libraries.
IEEE-compliant library with a fixed rounding mode (round to nearest) and no inexact exceptions.
IEEE-compliant library with a fixed rounding mode (round to nearest) and no exceptions.
Behaves like the
but additionally flushes denormals and infinities to zero.
This library behaves like the ARM VFP in Fast mode. This is the default.
IEEE-compliant library with configurable rounding mode and all IEEE exceptions.
Compiler support (helper function) library.
Transcendental math functions.
Non ISO C-compliant ISO C micro-library basic runtime support.
Non IEEE 754 floating-point compliant micro-library support.
An ARM only library for use with ARMv4.
An ARM/Thumb interworking library for use with ARMv4T.
An ARM/Thumb interworking library for use with ARMv5T and later.
A Thumb only library for use with ARMv6-M.
A Thumb only library for use with ARMv7-M.
A combined ARM and Thumb library for use
with Cortex-A and Cortex-R series processors. You can prevent this library being
selected using the linker option
A variant of the library for processors that have single-precision hardware floating-point only, such as Cortex-M4.
Uses VFP instruction set.
Position-independent access to static data.
FPIC addressing is enabled.
