From: Jin Yao <[email protected]> In annotate browser, we will add support to check fused instructions. While this is x86-specific feature so we need the annotate browser to know what the arch it runs on.
symbol__disassemble() has figured out the arch. This patch just lets the arch return from symbol__disassemble and save the arch in annotate browser.
