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

94 was too compilicated. The cache table did not allow values to be
95 computed from cache entries. #defines could only be used when a
96 cache was present, remove the restriction.
98 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
99 scratch variable is defined when a cache entry is beinf
100 filled. Change the definition of a COMPUTE variable to be defined
