Details:
- Updated the gemmd addon and the gemmlike sandbox code to use the new
microkernel calling sequence, which now includes m and n dimensions so
that the microkernel has all the information necessary to handle edge
cases. Thanks to Jeff Diamond for catching this, which ideally would
have been included in commit 54fa28b.
- Retired var2 of both gemmd and gemmlike to 'attic' directories and
removed their corresponding prototypes. In both cases, var2 was a
variant of the block-panel algorithm where edge-case handling was
abstracted away to a microkernel wrapper. (Since this is now the
official behavior of BLIS microkernels, I saw no need to have it
included as a separate code path.)
- Comment updates.
Details:
- Implemented a new feature called addons, which are similar to
sandboxes except that there is no requirement to define gemm or any
other particular operation.
- Updated configure to accept --enable-addon=<name> or -a <name> syntax
for requesting an addon be included within a BLIS build. configure now
outputs the list of enabled addons into config.mk. It also outputs the
corresponding #include directives for the addons' headers to a new
companion to the bli_config.h header file named bli_addon.h. Because
addons may wish to make use of existing BLIS types within their own
definitions, the addons' headers must be included sometime after that
of bli_config.h (which currently is #included before bli_type_defs.h).
This is why the #include directives needed to go into a new top-level
header file rather than the existing bli_config.h file.
- Added a markdown document, docs/Addons.md, to explain addons, how to
build with them, and what assumptions their authors should keep in
mind as they create them.
- Added a gemmlike-like implementation of sandwich gemm called 'gemmd'
as an addon in addon/gemmd. The code uses a 'bao_' prefix for local
functions, including the user-level object and typed APIs.
- Updated .gitignore so that git ignores bli_addon.h files.
