commit a95c4ad24cf83b2b0273fee73162bf476cebec8f
|
|
Author: Mark Wielaard <mjw@redhat.com>
|
|
Date: Fri Jul 4 14:30:48 2014 +0200

|
|
|
Add ppc64le ELFv2 abi support to backends and elflint.
|
|
|
|
The big endian vs little endian changes are already handled by detecting
|
|
the EI_DATA data encoding. And the function descriptors are already not
|
|
used when we see there is no .opd section. This change adds new checks
|
|
for st_other bits, new relocations and recognizes DT_PPC64_OPT.
