/*
** Default LDF for C, C++ and assembly applications targeting ADSP-BF537.
**
** 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.
** 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_SDRAM_STACK
** Use SDRAM for system stack rather than L1 default. Should allow for
** much larger stack but likely to have a significant performance impact.
** USE_SDRAM_HEAP
** Use SDRAM for dynamic heap allocation rather than L1 default. Should
** result in a much larger heap being available but can have a significant
** 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 run
** initialization.
