[llvm-commits] Fold() function on TargetFolder class - removal of redundant constantexpr

Hi Nick,

it would be nice if this (folding vs no folding) could be controlled with a
runtime flag.  If it was I would probably add it permanently to dragonegg.
Unfortunately the way IRBuilder is declared to take the folder as a template
parameter makes this hard.  Any ideas for how to achieve this?

Ciao, Duncan.
