/*
** LDF for ADSP-BF533.
** 
** There are a number of configuration options that can be specified
** either by compiler flags, or by linker flags directly. The options are:
** 
** USE_PROFILER0
** 	Enabled by -p. Link in profiling library, and write results to
** 	both stdout and mon.out.
** USE_PROFILER1
** 	Enabled by -p1. Only write profiling data to mon.out.
** USE_PROFILER2
** 	Enabled by -p2. Only write profiling data to stdout.
** USE_PROFILER
** 	Equivalent to USE_PROFILER0.
** __WORKAROUNDS_ENABLED
**    Defined by compiler when -workaround is used to direct LDF to
**    link with libraries that have been built with work-arounds
**    enabled.
** USE_FILEIO
**    Always defined; enables the File I/O Support, which is necessary
**    for printf() to produce any output.
** USE_CACHE
** 	Makes use of Some L1 memory as cache. Implies the presence
** 	of at least some external memory.
