software framework for high-performance BLAS-like libraries
BLIS is a portable software framework for instantiating high-performance
BLAS-like dense linear algebra libraries. The framework was designed
to isolate essential kernels of computation that, when optimized,
immediately enable optimized implementations of most of its commonly
used and computationally intensive operations.
===> The following configuration options are available for blis-2.1:
CBLAS=off: build the CBLAS compatibility layer
PARA=on: use pthread parallelization
===> Use 'make config' to modify these settings
math/blis: fix build with clang 19
Clang 19 has removed support for the -mavx512pf and -mavx512er flags,
for the Intel Xeon Phi (aka "Knights Landing"/knl or "Knights
Mill"/knm) [1] [2].
This causes fatal errors during configuration of math/blis:
Compiling obj/x86_64/kernels/knl/1m/bli_dpackm_knl_asm_24x8.o ('knl' CFLAGS
for kernels)
cc: fatal error: unknown argument '-mavx512pf'; did you mean '-mavx512f'?
gmake: *** [Makefile:653:
obj/x86_64/kernels/knl/1m/bli_dpackm_knl_asm_24x8.o] Error 1
Add an EXTRA_PATCHES entry to deal with this situation.
Note that in the future, this may also have to be done for gcc 15 and
later. In that case, the patch might be done unconditionally.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

math/blis: pacify portlint, add test target, optimize for power9 on powerpc64
1. Move USES block to pacify portlint.
2. Add test target.
3. Add perl as a build dependency, I'm not sure how it worked before.
4. Optimize for power9 on powerpc64. This will break blis on all earlier POWER
generations, but nothing depends on this port so I guess it's ok. make test
passes fine on both elfv1 and elfv2.
5. Remove LIBNAME, it's not necessary.

math/blis: update to release 0.5.0.
Most important addition to this release are mixed precision interfaces. This
allows one to, e.g., put in single precision data but carry the computation
out in double precision accuracy.
Note that flame/blis is the upstream for the BLIS library. AMD has forked
BLIS and releases independently from the FLAME project but is strightly
downstream.
math/blis: update to 0.4.0
This release incorporates the changes needed for us which were previously only
available through a snapshot. It also allows us to drop some install hacks and
brings general improvements to blis itself.
Switch to llvm6 as the compiler.

math/blis: update to post 0.3.2 snapshot.
Among other changes, this improves performance on recent AMD architectures and
contains the official runtime kernel selection we asked them for.

math/blis: update to the first snapshot working on FreeBSD to support runtime
kernel selection. For amd64, this will now select, if available, an assembly
optimized kernel for the CPU architecture blis is running on. The other
architectures continue to only use what is now called the generic kernel but in
theory arm and power7 assembly optimizations are available.
Due to this, remove the old explicit kernel selection. Also switch to use
devel/llvm50 as a compiler to actually support all the architectures (and
upstream compile flags) properly. This hopefully will also help with getting
blis to work on other architectures out of the box.

Mark some ports failing on powerpc64. These ports are either new
ports, or had been recently unblocked.
While here, pet portlint.

math/blis: Change to also always compile a shared library version of the
library. This is in line with other BLAS libraries in the tree.
While there, correct LOCALBASE to be PREFIX.

BLIS is a portable software framework for instantiating high-performance
BLAS-like dense linear algebra libraries. The framework was designed to isolate
essential kernels of computation that, when optimized, immediately enable
optimized implementations of most of its commonly used and computationally
intensive operations. BLIS is written in ISO C99 and available under a
BSD3CLAUSE. While BLIS exports a new BLAS-like API, it also includes a BLAS
compatibility layer which gives application developers access to BLIS
implementations via traditional BLAS routine calls. (from their github)
