/*
** 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.
