The “annotate immediates” flag in the x86 disassembler was changed from a global variable to a thread-local variable within the instr_info struct. This prevents unintended side effects in multi-threaded scenarios where disassembly functions are used concurrently. The change ensures that the annotation setting is specific to each disassembly operation.
