   1 # Makefile for libmagicrt
   2 #
   3 # The magic runtime library is the runtime state transfer component for live
   4 # update.  It is not a regular library.  First of all, it is only built when
   5 # MKMAGIC is enabled, which also implies that we are building bitcode.
   6 # Second, the produced file is a single bitcode object containing basically the
   7 # concatenation of the individual bitcode objects produced from the source
   8 # files.  The final bitcode object is used to link against system services
   9 # during the rest of the compilation process.  It is installed only because
  10 # this makes it easier to refer to it during the rest of the compilation
  11 # process.  However, both the library's generation and its installation cannot
  12 # be done with regular bsd.lib.mk rules, which is why this Makefile is rather
  13 # nonstandard.

  43 # HACK: keep the "temporary" .bc.o files generated as part of running the
  44 # sectionify pass, so that we can trick clang into taking bitcode objects
  45 # during the linking phase, because its driver refuses to take objects with
  46 # the .bc suffix even when using the gold plugin.  This works only because
  47 # we are using sectionify on all objects here, and because bsd.lib.mk uses
  48 # temporary names convenient for us.  See also the comment in bsd.lib.mk.
