--- Comment #5 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
This probably got fixed when early folding was fixed:
gcc 8.0 -Wsign-conversion -Wparentheses -Wall -Wextra -Wconversion gives:
<source>:3:48: warning: suggest parentheses around comparison in operand of '^'
[-Wparentheses]
unsigned short s = ~0x4578ADBCAA1DE677LL ^ a == 0;
~~^~~~
<source>:3:44: warning: unsigned conversion from 'long long int' to 'short
unsigned int' changes value from '-5005942011641849463' to '6537' [-Woverflow]
unsigned short s = ~0x4578ADBCAA1DE677LL ^ a == 0;
~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~
The fix-it notes for -Wparentheses and having some warnings enabled by default
would be nice, but they are a different topic altogether.
