  • posix/Makefile.am, posix/include/rtems/posix/priority.h, posix/include/rtems/posix/pthread.h, posix/inline/rtems/posix/priority.inl, posix/src/killinfo.c, posix/src/pthread.c, posix/src/pthreadcreate.c, posix/src/pthreadsetschedparam.c: Various modifications to improve binary code coverage analysis. Some of these are to mark code as debug only. Some are to break conditional expressions into multiple lines. Some are to move inline methods that are not time critical into subroutines to make them easier to test. Inlining them multiple times means that their logic paths are spread across multiple methods. This explodes the test cases required.
  • posix/src/psxpriorityisvalid.c, posix/src/psxtransschedparam.c: New files.
