libdwfl_stacktrace uses __libdwfl_set_initial_registers_thread but it
|
||||
is wrapped by #ifdef __linux__, causing build errors on non-Linux
|
||||
platforms.
|
||||
|
||||
* linux-pid-attach.c (__libdwfl_set_initial_registers_thread):
|
||||
Remove from inside the '#ifdef __linux__'.
|
||||
* dwfl_frame_regs.c (__libdwfl_set_initial_registers_thread):
|
||||
Move here.
