Subject: [PATCH] ldso: AVR32 startup hack
|
|
|
|
AVR32 needs to do both PERFORM_BOOTSTRAP_GOT and a full relocation of
|
|
the GOT. I don't quite remember why, but I think it's because some GOT
|
|
entries just need the load address added to them, while the rest need
|
|
the full relocation code.
|
|
|
|
This patch should be revisited to figure out whether we're processing
|
|
relocations against undefined symbols and whether that's something we
|
|
should be doing...
