Subject: [PATCH] ARM: Support loading unmarked objects from cache.
|
|
|
|
ARM now supports loading unmarked objects from
|
|
the dynamic loader cache. Unmarked objects can
|
|
be used with the hard-float or soft-float ABI.
|
|
We must support loading unmarked objects during
|
|
the transition period from a binutils that does
|
|
not mark objects to one that does mark them with
|
|
the correct ELF flags.
|
|
