As the v1 notes (among other things): https://lore.kernel.org/git/cover-0.8-00000000000-20211217T012902Z-avarab@xxxxxxxxx/ This speeds up noop runs of "make" by a lot. After a "make" running a "make -j1" with this is ~1.5 faster than on "master"[2], and around 3x as fast with "make -j1 NO_TCLTK=Y" (the TCL part takes a lot of time, but that's another matter). This v5 re-roll (for v3, see: https://lore.kernel.org/git/cover-v4-0.9-00000000000-20220302T124320Z-avarab@xxxxxxxxx/): * Drops the "wspfx" patch. * Rephrases the 1/8 commit message, dropping the mention of .DEFAULT_GOAL etc. I think this should be ready to advance now per Junio's comment on v4 (https://lore.kernel.org/git/xmqqpmn4jdhy.fsf@gitster.g/): Other than a few things I noticed and commented on, 1-7 and 9 looked all sensible.
