Patch rtems-rc-20000713-1-cvs.diff from Ralf Corsepius <corsepiu@…>
that is yet another multilib-related structual cleanup patch:

Changes:

  • Make RTEMS_TEST_NO_PAUSE a tests/ subpackage specific option.
    • Remove RTEMS_TEST_NO_PAUSE from custom/*.cfg, targopts.h and cpuopts.h.
    • Add autoconf macros RTEMS_*_RTEMS_TEST_NO_PAUSE (aclocal/rtems-test-no-pause.m4).
    • Add RTEMS_*_RTEMS_TEST_NO_PAUSE support to sptests/configure.ins and tmtests/configure.in. These are the only subdirectories which currently apply RTEMS_TEST_NO_PAUSE.
    • Add autoconf-DEFS support to all test subpackages' configure.ins below tests/. I.e. AC_DEFINES now get explicitly propagated as preprocessor defines into Makefiles, cf. AM_CPPFLAGS in tests/*/*.am, instead of using a global config-files.
    • Remove NDEBUG from custom/*.cfg.
  • AC_DEFINE POSIX_API, ITRON_API and MULTIPROCESSING in exec/configure.in, only.
    • All other sources now should relay on the values from cpuopts.h and should not define them themselves.
    • Several related changes to many configure.ins
  • Bug-fixes to RTEMS_*_RTEMS_DEBUG macros (Actually workarounds to quoting bugs in autoconf).

Notes:

  • This patch is rather immature and only tested for a small subset of BSPs (requires the tests to be enabled and therefore takes an tremendous amount of disc space and time.)
  • The patches to *cfg were generated by a script. Expect file formating changes :)
  • Property mode set to 100644

37#  CONSOLE_USE_INTERRUPTS (erc32_bsp)
38#     The erc32 console driver can operate in either polled or interrupt mode.
39#     Under the simulator (especially when FAST_UART is defined), polled seems
40#     to operate better.  It is common for a task to print a line (like the
41#     end of test message) and then exit.  In this case, the program returns
42#     control to the simulator command line before the program has even queued
43#     the output to the uart.  Thus sis has no chance of getting the data out.
44#
45#  SIMSPARC_FAST_IDLE (erc32_bsp)
46#     If defined, speed up the clock ticks while the idle task is running so
47#     time spent in the idle task is minimized.  This significantly reduces
48#     the wall time required to execute the RTEMS test suites.
49#
50#  FPU_REVB (erc32_bsp)
