A. Introduction
This document contains information about the math libraries provided with the Sun[tm] Studio compilers and tools.
This document describes the software corrections, known problems, limitations, and incompatibilities of this release.
Information in this document updates and extends information in the software manuals.
Product Documentation
- Release Notes: Available on the developer portal at http://developers.sun.com/sunstudio/documentation/ss12/release_notes.html. Information in the release notes updates and extends information in all readme files.
- Sun Studio Documentation: Product man pages, HTML versions of readmes, and manuals can be accessed from /installation_directory/docs/index.html. The default installation directory is /opt/SUNWspro.
- IDE Documentation: Online help for all components of the Sun Studio IDE can be accessed from the Help menu in the IDE.
- Developer Resources Portal: For technical articles, code samples, documentation, and a knowledge base, see the developers portal at http://developers.sun.com/sunstudio.
Note - If your Sun Studio compilers and tools have not been installed in the default /opt directory, ask your system administrator for the equivalent path on your system.
B. About the Sun Studio Math Libraries
This release of the math libraries is available on the Solaris[tm] Operating System (Solaris OS) versions 9, and 10, and on Linux.
For information on using the Sun Studio math libraries, see the Numerical Computation Guide or the section 3m man pages.
C. New and Changed Features
The following features were added or changed:
- Features added in the Solaris 10 OS:
- All of the math and floating point environment functions required by the latest version of the C language (C99) are now available in libm in the Solaris 10 OS. Previously, float and long double math functions were available only in libsunmath and the C99 floating point environment functions were available only in libm9x.
- The vector math function library libmvec is now included in the Solaris 10 OS. This library is provided as a shared object only.
- Deprecated Libraries:
- The following libraries are provided with the Sun Studio 12 software for backward compatibility, but their use is discouraged: libmvec (static archive), libm9x.
- libcopt is classified Obsolete and has been removed from the Sun Studio software release.
- The static archive versions of libmvec are still provided for programs compiled for the Solaris 8 OS and Solaris 9 OS. Programs compiled for the Solaris 10 OS should use the shared object version of this library. The static archive libmvec might be classified Obsolete and removed in a future release.
- As noted above, the contents of libm9x have been moved into libm in the Solaris 10 OS. libm9x is still provided for programs compiled for the Solaris 8 OS and Solaris 9 OS. Programs compiled for the Solaris 10 OS should use libm. libm9x might be classified Obsolete and removed in a future release.
The following features were added or changed in the previous release.
_Complex Support. The Sun Studio C compiler includes support for the _Complex and _Imaginary floating point types introduced in C99. In the Solaris 8 OS and Solaris 9 OS, support routines for arithmetic operations on _Complex and _Imaginary types are contained in the library libcplxsupp.a. You must specify -lcplxsupp when linking a program that uses these types. In the Solaris 10 OS, the complex support routines are contained in the system library, libc, which is linked automatically by the compiler.
See the C Compiler Readme for more information about support for C99 features.
