Clang is more verbose:
./test.c:4:11: warning: & has lower precedence than ==; == will be evaluated
first [-Wparentheses]
x = y & 1 == 1;
^~~~~~~~
./test.c:4:11: note: place parentheses around the '==' expression to silence
this warning
x = y & 1 == 1;
^

./test.c:4:11: note: place parentheses around the & expression to evaluate it
first
x = y & 1 == 1;
