|
In order to support hypervisor analysis of crash dumps, xen-syms needs
|
|
to contain debug_info. It should be allowed to configure the hypervisor
|
|
to be built with CONFIG_DEBUG_INFO in non-debug builds without having
|
|
to enable EXPERT.
|
|
|
|
Using a rather oldish gcc (7.5) it was verified that code generation
|
|
doesn't really differ between CONFIG_DEBUG_INFO on or off without
|
|
CONFIG_DEBUG being set (only observed differences were slightly
|
|
different symbol addresses, verified via "objdump -d", resulting from
|
|
the different config.gz in the binary). The old gcc version selection
|
|
was based on the assumption, that newer gcc won't regress in this
|
|
regard.
|
|
|
|
So move CONFIG_DEBUG_INFO out of the section guarded by EXPERT.
|
|
|
|
It should be mentioned that there have been reports that the linking
|
|
of the xen.efi might take considerably longer with CONFIG_DEBUG_INFO
|
|
selected when using newer binutils.
