Yes, emscripten compiles the relooper when it needs to be rebuilt (relooper code changed since last you ran it), and then uses it from the cache. So you only see this message when it is actually built, rarely.
The relooper is used in -O1 builds or above. (To confirm, check your functions are not just a single huge switch with tons of cases.) - Alon On Tue, Mar 18, 2014 at 7:21 PM, Mark Callow <[email protected]>wrote: > Hi, > > Is the message sequence about "bootstrapping relooper" something that only > happens the first time you do an optimized compile with a particular > Emscripten version on a particular machine?
