Code Issues Releases Activity

Fixed several instruction handling issues: 1) Added proper handling for zero displacements in memory operands, 2) Fixed large unsigned displacement values display, 3) Added CmpEaxImmHandler for CMP EAX, imm32 instruction, 4) Fixed JP and JNP conditional jump instruction types
