I should have mentioned this aspect, sorry. After some discussion, this was added to asm.js several months back,
http://discourse.specifiction.org/t/request-for-comments-switching-resizing-heaps-in-asm-js/641/18 so enabling this does *not* disable full asm.js speed. In other words, asm.js supports changing the heap size, and emscripten now allows that by default. - Alon On Wed, Feb 18, 2015 at 5:54 PM, Bruce Mitchener <bruce.mitche...@gmail.com> wrote: > This no longer has an impact on asm.js or needs a special asm.js mode? > > - Bruce > > On Thu, Feb 19, 2015 at 8:46 AM, Alon Zakai <alonza...@gmail.com> wrote: > >> The ALLOW_MEMORY_GROWTH option is now on by default on the incoming >> branch.
