WebGCC can't inline functions across translation units (unless you use LTO, and even then force_inline will certainly not be honored). If you want the compiler to have any chance of inlining, the compiler must obviously be able to see the implementation of the function being called from the call site. pigeon768 • 1 yr. ago Ohhhhhhhh.
