Patch rtems-rc-4.5.0-6-cvs.diff from Ralf Corsepius <corsepiu@…>.
The patch contains:

  • build variants support
  • Reworked make-exe custom/*.cfg for all targets (Should be self-explanatory, may still be incomplete)
  • Several fixes to custom/*.cfgs related to setting debug flags
  • Fixes to some bsp_specs for BSPs which apparently have never been build with debugging before ;)
  • pc386.cfg fix attempts (cf. my mail from earlier today)
  • Updated ampolish (No need to run it, the patch contains the result from having applied it)

Known bugs/deficiencies related to this work:

  • "make [clean|distclean]" support is still incomplete (e.g. "make clean" does not delete all Depends-o-*)
  • Completely untested for linux/posix and hppa.
  • Build failures of i960 BSPs (make VARIANT=DEBUG) - I guess, they are not related to this patch.
  • Successfully tested for all sh, sparc, i386, ppc, m68k BSPs (make VARIANT=DEBUG)
  • make VARIANT=PROFILE not supported by all BSPs (I don't care :)
  • make VARIANT=DEBUG failures below tests/ for some BSPs (e.g. gensh1), because of the tests's binaries being too large to fit into the target memory layout.
  • Property mode set to 100644

19#  This section makes the target dependent options file.
20
21#  NDEBUG (C library)
22#     if defined asserts do not generate code.  This is commonly used
23#     as a command line option.
24#
25#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
26#     do not pause between screens of output in the rtems tests
27#
28#  RTEMS_DEBUG (RTEMS)
29#     If defined, debug checks in RTEMS and support library code are enabled.
30#
31#  CONSOLE_USE_POLLED     (psim_bsp)
32#  CONSOLE_USE_INTERRUPTS (psim_bsp)
33#     The psim console driver has the structure to operate in either
34#     polled or interrupt mode.  However both modes only trap to the
35#     monitor currently.
36#
37#  PPC_VECTOR_FILE_BASE (ppc)
38#     This defines the base address of the exception table.
39#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
40#
41#  PPC_ABI (ppc)
42#     This defines the calling convention (Application Binary Interface)
43#     used in this configuration.  EABI is the only one supported.
44#
45#  PPC_ASM (ppc)
46#     This defines the assembly language format used in this configuration.
47#     ELF is the only one supported.
48#
49#  PPC_USE_SPRG (RTEMS PowerPC port)
50#     If defined, then the PowerPC specific code in RTEMS will use some
51#     of the special purpose registers to slightly optimize interrupt
52#     response time.  The use of these registers can conflict with
53#     other tools like debuggers.
54#
55#  PPC_USE_DATA_CACHE (RTEMS PowerPC port/BSP)
56#     If defined, then the PowerPC specific code in RTEMS will use
57#     data cache instructions to optimize the context switch code.
58#     This code can conflict with debuggers or emulators.  It is known
59#     to break the Corelis PowerPC emulator with at least some combinations
60#     of PowerPC 603e revisions and emulator versions.
61#     The BSP actually contains the call that enables this.
62#
63#  PPC_USE_INSTRUCTION_CACHE (RTEMS PowerPC port/BSP)
64#     If defined, then the PowerPC specific code in RTEMS will use
65#     data cache instructions to optimize the context switch code.
66#     This code can conflict with debuggers or emulators.
67#     The BSP actually contains the call that enables this.
