• File kcore/makefile — part of check-in [e794c5edef] at 2019-06-29 09:31:50 on branch trunk — add a bunch of code, port the header mechanism to gpp; add a fuckton of definitions and compatibility header code; notably, add core function kstop and x86.lin.{32,64} impl. update docs accordingly (user: lexi, size: 1345) [annotate] [blame] [check-ins using]

     7     17   # using to generate these headers is unbelievably heinous.
     8     18   # it's inelegant, it's gross, and it's horrible. in the long
     9     19   # term this NEEDS to be replaced with a bespoke solution
