4	# CALL rel32 (opcode E8)
5	# CALL r/m32 (opcode FF /2) with register operands
6	# CALL m32 (opcode FF /2) with memory operands
7	# SPECIAL CASES in x86 encoding:
8	# 1. When Mod=00 and R/M=100 (ESP), a SIB byte is required. The instruction FF14 is invalid because
9	# it's missing the required SIB byte. The correct encoding would use a SIB byte (e.g., FF1424).
10	# 2. When Mod=00 and R/M=101 (EBP), this doesn't actually refer to [EBP] but instead indicates
11	# CALL m32 (opcode FF /2) with SIB addressing
12	# SPECIAL CASE: SIB byte with EBP as base register
13	# When the SIB byte has Base=101 (EBP) and Mod=00, the base register is not used.
14	# Instead, a 32-bit displacement follows the SIB byte (similar to the Mod=00, R/M=101 special case).
15	# This instruction is commented out because it's not correctly recognized by many disassemblers.
16	# SPECIAL CASE: Another SIB byte with EBP as base register
17	# When the SIB byte has Base=101 (EBP) and Mod=00, the base register is not used.
18	# Instead, a 32-bit displacement follows the SIB byte (similar to the Mod=00, R/M=101 special case).
19	# This instruction is commented out because it's not correctly recognized by many disassemblers.
20	# CALL m32 (opcode FF /2) with displacement
21	# CALL m32 (opcode FF /2) with SIB and displacement
22	# CALL m16:32 (opcode FF /3) - Far call with memory operand
23	# SPECIAL CASE in x86 encoding:
24	# When Mod=00 and R/M=101 (EBP), this doesn't actually refer to [EBP] but instead indicates
25	# CALL m32 (opcode FF /2) with direct memory operand
26	# CALL m32 (opcode FF /2) with segment override prefixes
