# This is the actual bsp directory used during the build process.
RTEMS_BSP_FAMILY=simhppa

#  This contains the compiler options necessary to select the CPU model
#  and (hopefully) optimize for it.
#
#  Possibles:
#  -mpa-risc-1-1        -- HPPA 1.1 instead of 1.0
#  -mportable-runtime
#
CPU_CFLAGS = -mpa-risc-1-1 -mportable-runtime

# Possibles:
#  -Wall                -- lots of warnings
#  -pipe                -- compiler uses pipes to talk to phases (usually faster)
#  -ansi                -- ANSI C compliance
#  -fasm                -- ANSI, but allow inline assembler
#  -mgas                -- we are using gas as assembler
#  -fno-keep-inline-functions  -- do not emit any inlines as static
CFLAGS_DEFAULT = $(CPU_CFLAGS) -Wall -ansi -fasm -mgas

# optimize flag: typically -0, could use -O4 or -fast
# -O4 is ok for RTEMS
# NOTE: some level of -O may be actually required by inline assembler
CFLAGS_OPTIMIZE_V=-O4 -fno-keep-inline-functions

# Define this to yes if this target supports multiprocessor environments.
HAS_MP=yes

# This target does NOT support the TCP/IP stack so ignore requests
# to enable it.
HAS_NETWORKING=no

#  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
#
#  RTEMS_DEBUG (RTEMS)
#     If defined, debug checks in RTEMS and support library code are enabled.
#
#  SIMHPPA_FAST_IDLE (simhppa)
#     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.
