is it right that I can use convertUsersOfConstantsToInstructions to expand
constantexp to instructions? However, convertUsersOfConstantsToInstructions
changes other functions as well. An option to add an addition function
parameter to convertUsersOfConstantsToInstructions to ensure only constexpr
users in the function is expanded. @nikic WDYT of this option?
convertUsersOfConstantsToInstructions is also doing a DFS on user of User.
