svn commit: r212424 - head/share/mk

[Rui Paulo]

Author: rpaulo
Date: Fri Sep 10 16:27:09 2010
New Revision: 212424
URL: http://svn.freebsd.org/changeset/base/212424

Log:
  Add bsd.dtrace.mk. This allows userland programs and libraries to
  define USDT probes on a provider.d file and then use this new make
  infrastructure to build the corresponding header file and object file.
  
  This will only take effect when the user defines WITH_DTRACE when building.
