Observation about generated code:
$ x86_64-pc-linux-gnu-gcc -O2 -fno-tree-ccp -fno-tree-fre testcase.c -S -o-
...
foo:
        movl    %edi, %eax
        addb    %al, %al
        ret
...

which looks superior to code generated by -O1/-O2/-O3/-Os/-Og :
...
foo:
        movsbl  %dil, %edx
        addl    %edx, %edx
        movl    %edi, %eax
        movb    %dl, %al
        ret
...
