/*
** Default LDF for C, C++ and assembly applications targeting ADSP-BF561.
** Builds a single DXE for either COREA (default) or COREB (if macro defined)
** Partitions shared memory between two cores.
** 
** There are a number of configuration macros that may be specified as a 
** result of use of certain compiler switches or by linker flags directly.
** The options are:
** 
** __WORKAROUNDS_ENABLED
**   Defined by compiler to direct LDF to link with libraries that have 
**   been built with hardware errata workarounds enabled.
** USE_INSTRUCTION_CACHE, USE_DATA_A_CACHE, USE_DATA_B_CACHE, USE_CACHE
**   Avoids use of regions of L1 which will be configured for cache use. 
**   Use implies the presence SDRAM (external) memory.
** __ADI_MULTICORE
**   Causes the LDF to use thread-safe support and multicore support to 
**   ensure atomic access to global data and per-core private data. Defined 
**   when compiler switch -multicore is used.
** USE_SDRAM
**   Makes SDRAM available as standard program and data memory.
** USE_SCRATCHPAD_STACK
**   Use scratchpad for system stack. Note only 4k memory.
** USE_SCRATCHPAD_HEAP
**   Use scratchpad for dynamic heap allocation. Note only 4k memory.
** USE_L2_STACK, USE_SDRAM_STACK
**   Use L2/SDRAM for system stack rather than L1 default. Should allow for
**   much larger stack but likely to have a significant performance
** USE_L2_HEAP, USE_SDRAM_HEAP
**   Use L2/SDRAM for dynamic heap allocation rather than L1 default. Should
**   result in a much larger heap being available but can have a sig
**   performance impact.
** USER_CRT
**   Specifies a custom or System Builder generated CRT startup object to use.
** USER_CPLBTAB 
**   Specifies a custom or System Builder generated CPLB configuration 
**   definition.
** USE_FILEIO
**   Normally defined and causes linking of I/O support libraries.
** IEEEFP
**   Defined by the compiler when switch -ieee-fp is used to direct the
**   use of slower but more IEEE conformant floating-point emulation.
** _DINKUM_IO
**   Defined by the compiler when switch -full-io is used to direct the
**   use of the slower but more conformant Dinkum libc I/O support instead
**   of libio.
** USE_PROFILER0, USE_PROFILER1, and USE_PROFILER2
**   Defined by compiler when switch -p[1|2] is used to direct LDF to link
**   with suitable profiling support.
** __NO_STD_LIB
**   Defined by the compiler when switch -no-std-lib is used and causes
**   the LDF to avoid using the standard VisualDSP++ library search path.
** __MEMINIT__
**   Macro defined by the linker when -meminit is used to enable runtime
**   initialization.
