3Operation: OP_ADDCC_IMM
4
5	Add immediate that will set the carry flag.
6
7	dreg:
8		Destination register
9	inst_imm
10		Immediate value to add.
11	sreg1:
12		Source register to add.
13
14Operation: OP_CALL_HANDLER.
15
16	cil_code:
17		Points to the CIL where the LEAVE or LEAVE_S
18		instruction was found.
19
20	inst_target_bb:
21		The target basic block for this invocation.
22
23	This instruction must call the target basic block.
24
25Operation: OP_CISINST
26
27	Implements the CEE_MONO_CISINST opcode that is decoded from
28	the CIL stream.
29
30	This opcode takes as input an object reference and a class,
31	and leaves on the assigned register:
32
33		0. if the object is an instance of the class,
34		1. if the object is not instance of the class,
35		2. if the object is a proxy whose type cannot be determined.
36
37Operation: OP_CCASTCLASS
38
39	Implements the CEE_MONO_CCASTCLASS opcode that is decoded from
40	the CIL stream.
41
42	This opcode takes as input an object reference and a class,
43	and leaves on the assigned register:
44
45		0. if the object is an instance of the class,
46		1. if the object is a proxy whose type cannot be determined
47
48		throws an InvalidCastException exception otherwise.
49
50Operation: OP_LOCALLOC
51	inst_left:
52		The value
53                                ins->inst_left = *sp;
54                                ins->cil_code = ip;
55
56	This is the equivalent of alloca() in a C implementation: it
57	allocates a bunch of bytes on the stack dynamically. Local
58	variables are allocated statically in the stack instead.
59
60	It is implemented by moving the stack pointer according to the
61	platform ABI: you may need to keep a specific frame register
62	to address local variables when LOCALLOC is used (the PPC code
63	does this, for example: ifyou're doing the s390 port I suggest
64	starting from that)
65
66Operation: OP_SUBCC_IMM
67
68	Substract immediate that will set the borrow flag.
69
70	dreg:
71		Destination register
72	inst_imm
73		Immediate value to add.
74	sreg1:
75		Source register to add.
