Subject: If a target uses a GOT, put it in the jt data section, not the text
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0336fdba858830d515bf53ac29b8e5ff24dfa823;p=oota-llvm.git

If a target uses a GOT, put it in the jt data section, not the text
section.  This will fix alpha when Andrew implements
AlphaTargetMachine::getTargetLowering().
