This subclause contains text, which is intended for use with the C or C++ preprocessor. By appropriately defining the macros OPDEF and OPALIAS before including this text, it is possible to use this to produce tables or code for handling CIL instructions. The
OPDEF macro is passed 10 arguments, in the following order:
-
A symbolic name for the opcode, beginning with
CEE_ -
A string that constitutes the name of the opcode and corresponds to the names given in Partition III.
-
Data removed from the stack to compute this operations result. The possible values here are the following:
-
Pop0– no inputs -
Pop1– one value type specified by data flow -
Pop1+Pop1– two input values, types specified by data flow -
PopI– one machine-sized integer -
PopI+Pop1– Top of stack is described by data flow, next item is a native pointer -
PopI+PopI– Top two items on stack are integers (size can vary by instruction) -
PopI+PopI+PopI– Top three items on stack are machine-sized integers -
PopI8+Pop8– Top of stack is an 8-byte integer, next is a native pointer -
PopI+PopR4– Top of stack is a 4-byte floating point number, next is a native pointer -
PopI+PopR8– Top of stack is an 8-byte floating point number, next is a native pointer -
PopRef– Top of stack is an object reference -
PopRef+PopI– Top of stack is an integer (size can vary by instruction), next is an object reference -
PopRef+PopI+PopI– Top of stack has two integers (size can vary by instruction), next is an object reference -
PopRef+PopI+PopI8– Top of stack is an 8-byte integer, then a native-sized integer, then an object reference -
PopRef+PopI+PopR4– Top of stack is an 4-byte floating point number, then a native-sized integer, then an object reference -
PopRef+PopI+PopR8– Top of stack is an 8-byte floating point number, then a native-sized integer, then an object reference -
VarPop– variable number of items used, see Partition III for details
-
-
Amount and type of data pushed as a result of the instruction. The possible values here are the following:
-
Push0– no output value -
Push1– one output value, type defined by data flow. -
Push1+Push1– two output values, type defined by data flow -
PushI– push one native integer or pointer -
PushI8– push one 8-byte integer -
PushR4– push one 4-byte floating point number -
PushR8– push one 8-byte floating point number -
PushRef– push one object reference -
VarPush– variable number of items pushed, see Partition III for details
-
-
Type of in-line argument to instruction. The in-line argument is stored with least significant byte first ("little endian"). The possible values here are the following:
-
InlineBrTarget– Branch target, represented as a 4-byte signed integer from the beginning of the instruction following the current instruction. -
InlineField– Metadata token (4 bytes) representing a FieldRef (i.e., a MemberRef to a field) or FieldDef -
InlineI– 4-byte integer -
InlineI8– 8-byte integer -
InlineMethod– Metadata token (4 bytes) representing a MethodRef (i.e., a MemberRef to a method) or MethodDef -
InlineNone– No in-line argument -
InlineR– 8-byte floating point number -
InlineSig– Metadata token (4 bytes) representing a standalone signature -
InlineString– Metadata token (4 bytes) representing a UserString -
InlineSwitch– Special for the switch instructions, see Partition III for details -
InlineTok– Arbitrary metadata token (4 bytes), used forldtokeninstruction, see Partition III for details -
InlineType– Metadata token (4 bytes) representing a TypeDef, TypeRef, or TypeSpec -
InlineVar– 2-byte integer representing an argument or local variable -
ShortInlineBrTarget– Short branch target, represented as 1 signed byte from the beginning of the instruction following the current instruction. -
ShortInlineI– 1-byte integer, signed or unsigned depending on instruction -
ShortInlineR– 4-byte floating point number -
ShortInlineVar– 1-byte integer representing an argument or local variable
-
-
Type of opcode. The current classification is of no current value, but is retained for historical reasons.
-
Number of bytes for the opcode. Currently 1 or 2, can be 4 in future
-
First byte of 2-byte encoding, or 0xFF if single byte instruction.
-
One byte encoding, or second byte of 2-byte encoding.
-
Control flow implications of instruction. The possible values here are the following:
BRANCH– unconditional branchCALL– method callCOND_BRANCH– conditional branchMETA– unused operation or prefix codeNEXT– control flow unaltered ("fall through")RETURN– return from methodTHROW– throw or rethrow an exception
The OPALIAS macro takes three arguments:
-
A symbolic name for a "new instruction" which is simply an alias (renaming for the assembler) of an existing instruction.
-
A string name for the "new instruction."
-
The symbolic name for an instruction introduced using the OPDEF macro. The "new instruction" is really just an alternative name for this instruction.
