Last change on this file since 6a14ae56 was 6a14ae56, checked in by Joel Sherrill <joel.sherrill@…>, on Jan 19, 1999 at 8:24:56 PM

Added comments to indicate what options are required to take advantage
of removal of unused function code found in newer binutils/egcs
snapshots. Early test with psim and hello.exe showed about a 13%
gain.

17#  NDEBUG (C library)
18#     if defined asserts do not generate code.  This is commonly used
19#     as a command line option.
20#
21#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
22#     do not pause between screens of output in the rtems tests
23#
24#  RTEMS_DEBUG (RTEMS)
25#     If defined, debug checks in RTEMS and support library code are enabled.
26#
27#  CONSOLE_USE_POLLED     (psim_bsp)
28#  CONSOLE_USE_INTERRUPTS (psim_bsp)
29#     The psim console driver has the structure to operate in either
30#     polled or interrupt mode.  However both modes only trap to the
31#     monitor currently.
32#
33#  PSIM_FAST_IDLE (psim_bsp)
34#     If defined, speed up the clock ticks while the idle task is running so
35#     time spent in the idle task is minimized.  This significantly reduces
36#     the wall time required to execute the RTEMS test suites.
37#
38#  PPC_VECTOR_FILE_BASE (PowerPC)
39#     This defines the base address of the exception table.
40#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
41#
42#  PPC_ABI (PowerPC)
43#     This defines the calling convention (Application Binary Interface)
44#     used in this configuration.  EABI is the only one supported.
45#
46#  PPC_ASM (PowerPC)
47#     This defines the assembly language format used in this configuration.
48#     ELF is the only one supported.
49#
50#  PPC_USE_SPRG (RTEMS PowerPC port)
51#     If defined, then the PowerPC specific code in RTEMS will use some
52#     of the special purpose registers to slightly optimize interrupt
53#     response time.  The use of these registers can conflict with
54#     other tools like debuggers.
