Subject: Several tail call tests apparently rely upon this being "adjusts stack" instead
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=f84d60b6495d059be725b432c0adf2fdf780dad6;p=oota-llvm.git

Several tail call tests apparently rely upon this being "adjusts stack" instead
of "has calls". That's probably wrong, but it needs further
investigation. Revert to the original behavior until this is settled.
