Do you perhaps call to GL via custom manually obtained function pointers? (i.e. eglGetProcAddress or similar) If so, that will exactly amount to a invoke_xx() statement, since that will cause an asm.js code call to non-asm.js code via a function pointer. In Emscripten, all GL functions are available by static linking at compilation time - even all functions for all WebGL extensions. For best performance, the xxxGetProcAddress route should be avoided.
