description: >
  Pointer compress the top level heap->strtable[] string table.  On 32-bit
  targets this saves 2 bytes per entry, e.g. for 256 entries 0.5kB.  However,
  the additional pointer compression code increases footprint by 200-300
  bytes.  The option also reduces performance a little bit, so this should
  be enabled when RAM is much more constrained than ROM.
