Subject: [uml-devel] Getting fault address from a SIGSEGV
Date: Sat, 19 Mar 2005 14:44:44 +0100 [thread overview]
Message-ID: <423C2CCC.9040809@cs.unibo.it> (raw)
Hi all,
For a project I'm working on, I would need to get the fault address of
a ptraced child, whose SIGSEGV I've caught. I've tried to dig in UML
source code to get how this is done, but I get lost after having
followed the chain segv_handler <- sig_info <- sig_handler_common_tt <-
"r = &TASK_REGS(get_current())->tt;", since there the status I was
looking for is stored in the thread_struct.regs, but I don't know where
in the code such status is filled, and so where such information is
taken from :-)
Hope you can light my way through the code ;-)
