# This makes the target dependent options file
# NDEBUG (C library)
# if defined asserts do not generate code. This is commonly used
# as a command line option.
#
# RTEMS_TEST_NO_PAUSE (RTEMS tests)
# do not pause between screens of output in the rtems tests
#
# NO_TABLE_MOVE (SPARC PORT)
# do not have a second trap table -- use the BSP's
#
# RTEMS_DEBUG (RTEMS)
# If defined, debug checks in RTEMS and support library code are enabled.
#
# CONSOLE_USE_POLLED (erc32_bsp)
# CONSOLE_USE_INTERRUPTS (erc32_bsp)
# The erc32 console driver can operate in either polled or interrupt mode.
# Under the simulator (especially when FAST_UART is defined), polled seems
# to operate better. It is common for a task to print a line (like the
# end of test message) and then exit. In this case, the program returns
# control to the simulator command line before the program has even queued
# the output to the uart. Thus sis has no chance of getting the data out.
#
# SIMSPARC_FAST_IDLE (erc32_bsp)
# If defined, speed up the clock ticks while the idle task is running so
# time spent in the idle task is minimized. This significantly reduces
# the wall time required to execute the RTEMS test suites.
#
# FPU_REVB (erc32_bsp)
# If defined, enables work-around for bug 3.14 in FPU rev.B or rev.C
