Details: - Developed by @fgvanzee and @devinamatthews. - Level-0 scalar macros have moved from a named-based system (e.g. `bli_dcopys( ... )`) to a macro argument-based system (`bli_tcopys( d,d, ... )`). - All macros are explicitly mixed-type. - All input and output operands can have a distinct type (precision and/or domain). Unnecessary computations and spurious NaN/Inf propagation are avoided in mixed-domain cases. - All macros which do math (i.e. not copy/set/etc.) take an additional computational precision. - Tile-level macros, 1m, broadcast-B, and other extensions are also included. - All macros should correctly handle aliasing of input and output operands (this needs to be rigorously checked). - The macros work generically over the defined types -- new types only need limited support (primarily conversion to other types and basic math).

@fgvanzee everything works now, with a full level-0 testsuite. "In-place" axpys, axpbys, xpbys, and scal2s also tested and work correctly. |

Awesome! Many thanks for finishing this up. |

There was a problem hiding this comment.
Seems to be a search-and-replace misfire.

Oh wait, or maybe it's not a typo? Is this meant as a to reference the bli_pthread_*() API wrapper?

Yep, please revert.

I didn't review the C++ files, but everything else looks good.

OK, I'll want to wait to merge this 'til I clear a few of the other PRs out of the queue. |

@fgvanzee are we out of Travis CI credits again? |
Also add some missing in-place tests.

Details: - Developed by @fgvanzee and @devinamatthews. - Level-0 scalar macros have moved from a named-based system (e.g. `bli_dcopys( ... )`) to a macro argument-based system (`bli_tcopys( d,d, ... )`). - All macros are explicitly mixed-type. - All input and output operands can have a distinct type (precision and/or domain).

Behavior is unchanged. - A standalone, templated C++ testsuite for the level-0 macros has been added. It is currently included as part of the CircleCI tests. - Const-correctness of level-0 macros is also checked. (cherry picked from commit a014a08)
