HardwareSerial: Define no-op serialEvent() functions for clang
698ad5d 
GCC automatically resolves weakly defined empty symbols to null if not overridden, but Clang doesn't resolve it this way. This causes undefined reference errors during linking.

To address this, define empty no-op serialEvent() functions that can be overridden later since its weakly defined, ensuring compatibility with Clang and fixing the build issue.

Looks ok to me. Did you verify this still works as expected on gcc (with and without a user serialEvent detected)?

Looks ok to me. Did you verify this still works as expected on gcc (with and without a user serialEvent detected)?

The patch was successfully tested with GCC in Arduino ide, both with and without a user-defined serialEvent. The functionality works as expected in both cases.

Test code:

void setup() {
  Serial.begin(9600);
  Serial.println("Testing serialEvent()");
}

void loop() {
  if (Serial.available()) {
    Serial.println("Processing data in serialEvent()");
  }
  delay(1000);
}

void serialEvent() {
  while (Serial.available()) {
    char c = Serial.read();
    Serial.print("Received: ");
    Serial.println(c);
  }
}

The code compiled perfectly and i was able to test it out with Serial monitor.

A slight flash size reduction was observed when compiling code without a user-defined serialEvent function. This occurs because GCC now identifies the weak symbols as explicitly defined no-ops, allowing for more aggressive dead code elimination.
