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.

C. New and Changed Features

The following features were added or changed:

• Sun Studio 12 Update 1 compilers now support the x86/x64 SSE 4.1 and SSE 4.2 instruction sets. Sun Studio math libraries include versions of libmopt, the optimized math library, and libm.il, the libm inline templates, that use SSE 4.1 and SSE 4.2 instructions. For best performance on processors that implement these instruction sets, specify the appropriate -xarch value when compiling and linking.
  
  
• 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 have been classified Obsolete: libmvec.a, libmvec_mt.a, and libm9x.so. Use of these libraries is discouraged. They may be removed in a future release. Programs currently using the vector elementary functions in libmvec.a or libmvec_mt.a should be relinked to use the shared version of these libraries supplied with the Solaris OS, libmvec.so. Programs currently using libm9x.so should be relinked to use the standard Solaris math library, libm.
  • libcplxsupp.a has been removed. C99 complex arithmetic support routines are provided in libc on Solaris 10 and above. Programs that use _Complex types and arithmetic should no longer link with -lcplxsupp.
  • On SPARC platforms, v8-only libmopt.a and libm.il have been removed. Programs must be linked with -xarch=v8plus (the default) or above.
