43 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

104 was too compilicated. The cache table did not allow values to be
105 computed from cache entries. #defines could only be used when a
106 cache was present, remove the restriction.
108 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
109 scratch variable is defined when a cache entry is beinf
