10 | * Table compression uses all the unused char codes on the symbols and |
11 | * maps these to the most used substrings (tokens). For instance, it might |
12 | * map char code 0xF7 to represent "write_" and then in every symbol where |
13 | * "write_" appears it can be replaced by 0xF7, saving 5 bytes. |
14 | * The used codes themselves are also placed in the table so that the |
15 | * decompresion can work without "special cases". |
16 | * Applied to kernel symbols, this usually produces a compression ratio |
17 | * of about 50%. |
