  38 # By default, we define the source directory for libraries to be
  39 # one level up from the ISA-specific directory, where the code is
  40 # actually built.  Many libraries define a 'common' directory to
  41 # contain the source.  These libraries must redefine SRCDIR as:
  42 #       SRCDIR = ../common
  43 # Other variations are possible (../port, ../src, etc).
  44 #
  45 SRCDIR =        ..
  46 
  47 #
  48 # We define MAPFILES here for the benefit of most libraries, those that
  49 # follow the convention of having source files and other common files
  50 # in the $(SRCDIR) directory.  Libraries that do not follow this
  51 # convention must define MAPFILES, or MAPFILEDIR for themselves.
  52 # Libraries that do follow this convention but that need supplemental
  53 # ISA-specific mapfiles can augment MAPFILES like this:
  54 #       MAPFILES += mapfile-vers

  61 # install rule in lib/Makefile.targ to generate false matches if there

  63 # one common example).  To prevent this, we set HDRDIR to a directory
