Subject: Emit pic jumptables to the same section that the function is emitted to,
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e08d6e915eba62bacc4441b3d4b24bbed67cd6a0;p=oota-llvm.git

Emit pic jumptables to the same section that the function is emitted to,
allowing label differences to work.  This fixes CodeGen/X86/pic_jumptable.ll
