New Revision: 244692
URL: http://svnweb.freebsd.org/changeset/base/244692

Log:
  Fix libproc test case to work with clang premature optimization
  observed with -O2 (used by default).
  Avoid function inlining for t1_bkpt_t on which we set a breakpoint.
  Otherwise the address of the function is never called thus the
  breakpoint never triggers.
