4	# LEA r32, m (opcode 8D) with basic addressing modes
5	# SPECIAL CASE: When Mod=00 and R/M=101 (EBP), this doesn't actually refer to [EBP].
6	# Instead, it's a special case that indicates a 32-bit displacement-only addressing mode.
7	# Adding the correct test case:
8	# LEA r32, m (opcode 8D) with displacement
9	# LEA r32, m (opcode 8D) with negative displacement
10	# LEA r32, m (opcode 8D) with SIB byte (no displacement)
11	# SPECIAL CASE: The following encodings with EBP as base register have special rules.
12	# When the SIB byte has Base=101 (EBP) and Mod=00, the base register is not used.
13	# Instead, a 32-bit displacement follows the SIB byte (similar to the Mod=00, R/M=101 special case).
14	# These instructions are commented out because they're invalid without the 32-bit displacement.
15	# The correct encoding would include a 32-bit displacement after the SIB byte.
16	# LEA r32, m (opcode 8D) with SIB byte and displacement
17	# LEA r32, m (opcode 8D) with direct memory operand
18	# LEA with different destination registers
19	# SPECIAL CASE: The following encodings are invalid for LEA instructions.
20	# When Mod=11 (bits 7-6 of the ModR/M byte), the R/M field specifies a register, not a memory location.
21	# LEA requires a memory operand as its second operand
22	# Valid LEA instructions with different destination registers (using Mod=00)
23	# LEA with complex addressing modes
