We should do better. staprun could detect & change that flag temporarily. The runtime could attempt to use kallsyms_lookup to find _stext self-sufficiently. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
