%description
TomsFastMath is a fast public domain, open source, large integer arithmetic
library written in portable ISO C.  It is a port of LibTomMath with optional
support for inline assembler multipliers.  It has the following features: 
 * Builds with GCC [preferably v3.3.x or higher] on any 32-bit/64-bit box
 * Includes ASM optimizations (inline) for
    - x86-32 (e.g. i386 and SSE2)
    - x86-64 (e.g. AMD64)
    - ARM (ARMv4 and higher)
    - PPC32 (e.g. G3/G4)
    - PPC64 (e.g. G5)
    - AVR32 (Atmel 32-bit RISC processor)
    - MIPS (32-bit) 
 * Includes fairly complete API (provides most of what LibTomMath provides)
 * Uses similar API as LibTomMath makes porting easy
 * Competitive speeds (and getting higher).
    - Faster than OpenSSL on the AMD64
    - Still room for improvements 
 * No heap usage (malloc/calloc/free)
 * Uses only inline asm, simplifies build process, simple to add new ports

The library is available as 32-bit and 64-bit.

Group:          Development/Libraries
Requires:       %{name} = %{version}-%{release}

%description    devel
The %{name}-devel package contains libraries and header files for
developing applications that use %{name}.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc_r -q64" or "gcc -maix64".
