Is getting rid of the GOT pointer really enough to make it work? Trying to copy an entire function is a very tenuous process, and it seems like it could easily break (if not now, then in the future) on things like assuming that the function is contiguous, or relative jmp/call, or TCO... (2) Along the lines of comment 22, while x86-32 PIC is arguably not even worthwhile, x86-64 PIC is all but built in, and definitely more performant. AFAIU it won't be broken by hot-patching in the same way that x86 PIC is, but it could certainly be broken by function copying (unless, of course, the copier is smart enough to understand RIP-relative addressing). Is this a concern? Are you aware of schemes that might need -fno-PIC on x86-64? Though, if Gabriel is correct that Windows uses PIC there, I guess this is unlikely. (2b) Similarly, what about ARM? (What does PIC even look like on ARM?) -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
