# 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

#  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.
