Description
I'm experiencing the following warnings when compiling my Qt project against WebAssembly:
emcc: warning: cannot represent a NaN literal '0x55e921c2a920' with custom bit pattern in NaN-canonicalizing JS engines (e.g. Firefox and Safari) without erasing bits! in ret double 0x7FF4000000000000 in _ZL7qt_snanv() emcc: warning: cannot represent a NaN literal '0x55e921c2a920' with custom bit pattern in NaN-canonicalizing JS engines (e.g. Firefox and Safari) without erasing bits! in ret double 0x7FF4000000000000 in _ZL7qt_snanv.31612()
It would be nice if these warnings could somehow be handled or muted, so that the build becomes more clean. However, I'm not sure if Qt is actually to blame for these warnings, or if the warnings should instead be handled Emscripten side.
