Subject: Recently changed getelementptr to use 'long' indexes for sequential types
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0235fe2b72af319a54c893887732b81df4c59906;p=oota-llvm.git

Recently changed getelementptr to use 'long' indexes for sequential types
instead of uints.  This adds a translation scheme to be backwards compatible
with old .ll files.
