# debug flags: opt. is needed to fit in RAM. '-O1' has shown bad side-

# effects by failing to set up some hardware I/O registers in

# c/src/lib/libbsp/sh/gensh2/startup/hw_init.c (and perhaps elsewhere),

# which prevented proper chip initialization and muted SCI1 output.

# optimize flag: typically -0, could use -O4 or -fast

# -O4 is ok for RTEMS

#  This section 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

#

#  RTEMS_DEBUG (RTEMS)

#     If defined, debug checks in RTEMS and support library code are enabled.

#

#  STANDALONE_EVB

#     This switch compiles code to jump-start from FLASH, without a monitor

#

#  START_HW_INIT

#     This switch selects whether 'early_hw_init()' is called from

#     'start.S'; 'bsp_hw_init()' is always called from 'bspstart.c'
