Operation: OP_ADDCC_IMM
|
||
|
|
|
||
|
|
Add immediate that will set the carry flag.
|
||
|
|
|
||
|
|
dreg:
|
||
|
|
Destination register
|
||
|
|
inst_imm
|
||
|
|
Immediate value to add.
|
||
|
|
sreg1:
|
||
|
|
Source register to add.
|
||
|
|
|
||
|
|
Operation: OP_CALL_HANDLER.
|
||
|
|
|
||
|
|
cil_code:
|
||
|
|
Points to the CIL where the LEAVE or LEAVE_S
|
||
|
|
instruction was found.
|
||
|
|
|
||
|
|
inst_target_bb:
|
||
|
|
The target basic block for this invocation.
|
||
|
|
|
||
|
|
This instruction must call the target basic block.
|
||
|
|
|
||
|
|
Operation: OP_CISINST
|
||
|
|
|
||
|
|
Implements the CEE_MONO_CISINST opcode that is decoded from
|
||
|
|
the CIL stream.
|
||
|
|
|
||
|
|
This opcode takes as input an object reference and a class,
|
||
|
|
and leaves on the assigned register:
|
||
|
|
|
||
|
|
0. if the object is an instance of the class,
|
||
|
|
1. if the object is not instance of the class,
|
||
|
|
2. if the object is a proxy whose type cannot be determined.
|
||
|
|
|
||
|
|
Operation: OP_CCASTCLASS
|
||
|
|
|
||
|
|
Implements the CEE_MONO_CCASTCLASS opcode that is decoded from
|
||
|
|
the CIL stream.
|
||
|
|
|
||
|
|
This opcode takes as input an object reference and a class,
|
||
|
|
and leaves on the assigned register:
|
||
|
|
|
||
|
|
0. if the object is an instance of the class,
|
||
|
|
1. if the object is a proxy whose type cannot be determined
|
||
|
|
|
||
|
|
throws an InvalidCastException exception otherwise.
|
||
|
|
|
||
|
|
Operation: OP_LOCALLOC
|
||
|
|
inst_left:
|
||
|
|
The value
|
||
|
|
ins->inst_left = *sp;
|
||
|
|
ins->cil_code = ip;
|
||
|
|
|
||
|
|
This is the equivalent of alloca() in a C implementation: it
|
||
|
|
allocates a bunch of bytes on the stack dynamically. Local
|
||
|
|
variables are allocated statically in the stack instead.
|
||
|
|
|
||
|
|
It is implemented by moving the stack pointer according to the
|
||
|
|
platform ABI: you may need to keep a specific frame register
|
||
|
|
to address local variables when LOCALLOC is used (the PPC code
|
||
|
|
does this, for example: ifyou're doing the s390 port I suggest
|
||
|
|
starting from that)
|
||
|
|
|
||
|
|
Operation: OP_SUBCC_IMM
|
||
|
|
|
||
|
|
Substract immediate that will set the borrow flag.
|
||
|
|
|
||
|
|
dreg:
|
||
|
|
Destination register
|
||
|
|
inst_imm
|
||
|
|
Immediate value to add.
|
||
|
|
sreg1:
|
||
|
|
Source register to add.
