The ATLAS (Automatically Tuned Linear Algebra Software) project is
an ongoing research effort focusing on applying empirical techniques
in order to provide portable performance. 

At present, it provides C and Fortran77 interfaces to a portable,
efficient BLAS implementation, as well as enhanced versions of 
a few routines from LAPACK.

If you want to link software to ATLAS rather than the standard BLAS, simply 
use -lf77blas -latlas (order is important), or -lptf77blas -latlas for the 
threaded library (which is primarily useful on SMP machines), in place of 
the usual -lblas.  Corresponding pure C versions of the ATLAS libraries are 
also included, in libcblas and libptcblas.

The ATLAS-enhanced LAPACK routines are also provided.
To link software with this library instead of the standard LAPACK, for example, use 
-L/usr/local/lib/gcc-4.2.3 -L/usr/local/lib/gcc-4.2.3/gcc/i386-portbld-freebsd7.0/4.2.3 -lalapack -lf77blas -lcblas -latlas -lgfortranbegin -lgfortran -lm, or 
-L/usr/local/lib/gcc-4.2.3 -L/usr/local/lib/gcc-4.2.3/gcc/i386-portbld-freebsd7.0/4.2.3 -lalapack_r -lptf77blas -lptcblas -latlas -lgfortranbegin -lgfortran
-lm for the threaded library, in place of the usual -llapack.
Note that
-L/usr/local/lib/gcc-4.2.3 -L/usr/local/lib/gcc-4.2.3/gcc/i386-portbld-freebsd7.0/4.2.3
depends on your environment.

Update to 3.8.2.

Submitted by:    Kengo Ichiki <ichiki@ualberta.ca>
Slightly modified so that his patches fit ports policy.

* Fix bug listed in http://math-atlas.sourceforge.net/errata.html#RMAAT .
* Bump portrevision.
* Fix pkg-descr. Still do not pass portlint though.

Submitted by:   bf <bf2006a@yahoo.com>

Use MANUAL_PACKAGE_BUILD instead.

Update to 3.8.0.

Only verified on i386 and amd64 FreeBSD 7BETA.

Discussions with: bf <bf2006a@yahoo.com>, truckman
and Tijl Coosemans <tijl@ulyssis.org>.

PR: 118270 and 118271

Using new LAPACK 3.1.1 port (threfore BUMPPORTREVISION)
and unbreak.

Temporary marked as broken. Creating ATLAS'ed LAPACK part is now broken.

In ATLAS/INSTALL.txt it is said that gcc42 is superior to both gcc3 and gcc41
- and FreeBSD 7 current imported gcc42.

Now we use USE_FORTRAN=yes to use FORTRAN compiler.

Fix errata listed at http://math-atlas.sourceforge.net/errata.html and
bump portrevision.

Submitted by:   bf <bf2006a@yahoo.com>

For test target, now we use GMAKE to MAKE. In some environment
GMAKE fails.

Remove CONFLICT line as elmer-mathlibs are deprecated by migration
to gfortran.

Atlas should not depend on GNU F77. Now
it doesn't expect existence of /usr/include/g2c.h

gmake is needed as a build dependency.

Fix build with WITH_OPTIMIZED_FLAGS.

* Migrate to gfortran. but stock GCC is used.
* lapack/blas are compiled with gforntran, thus we build TEST section as well.

* Shared lib number has been bumped 1 to 2
* Bump port revision

* Migrate to gfortran.
* portlint.
* (option) Installing benchmark tests for real FLOPS.
* Bump portrevision.

Fix error when WITH_OPTIMIZED_FLAGS is specified.

Currently with "cpu I686_CPU" which is default,
kernel automatically enables SSE if it is available.
so remove messages which are not necessary.

Add cputype of sempron; athlon type CPU

Submitted by: Pedro A M Vazquez <vazquez@iqm.unicamp.br>

Set NO_PACKAGE: atlas optimizes for the local machine, so a package is not
generally useful.

Reviewed by:    maho (maintainer)

Add two patches for stable builds.
o L1 cache size is not correctly detected having a bad clock
o in some case small number of tries in tuning doesn't meet convergence
  see FAQ http://math-atlas.sourceforge.net/errata.html#tol

At Kris's request, back out the MACHINE_ARCH spelling correction until
after 5.4-RELEASE.

Assist getting more ports working on AMD64 by obeying the
Ports Collection documentation and use 'ARCH' rather than 'MACHINE_ARCH'.

o Significantly performance loss by overriding several

Do not hardcord PICFLAG
Submitted by:   ru

Backout previous change of PICFLAG, since
behaviour of -fPIC and -fpic are different.
Here is the comment form obrien:

--
"-fpic" is a [minor?] optimization for machines that can handle it:

  -fpic
    Generate position-independent code (PIC) suitable for use in a shared
    library, if supported for the target machine. Such code accesses all
    constant addresses through a global offset table (GOT). The dynamic
    loader resolves the GOT entries when the program starts (the dynamic
    loader is not part of GCC; it is part of the operating system). If
    the GOT size for the linked executable exceeds a machine-specific
    maximum size, you get an error message from the linker indicating

-fPIC is appropreate on all architectures.
