---- Reported by bmaurer@users.sf.net 2004-07-22 16:40:37 MST ----

An opcode such as CEE_LDLEN should be decomposed before BURG sees it. When
we decompose the operation, BURG is able to see that the ldlen is really
LD_IND_I4 (base). It can use this information to combine the operation into
another assembly instruction (for example, it can do cmp DWORD PTR
[eax+length_offset], 5)
