On Ubuntu 20.04, when building with clang -Werror -Wextra-semi-stmt
(which is not the default build configuration), the compiler reports:
sha1.c:90:21: error: empty expression statement has no effect;
remove unnecessary ';' to silence this warning
[-Werror,-Wextra-semi-stmt]
R0(a,b,c,d,e, 0); R0(e,a,b,c,d, 1); R0(d,e,a,b,c, 2); R0(c,d,e,a,b, 3);
^
In file included from selinux_restorecon.c:39:
./label_file.h:458:15: error: empty expression statement has no
effect; remove unnecessary ';' to silence this warning
[-Werror,-Wextra-semi-stmt]
lineno);
^
Introduce "do { } while (0)" blocks to silence such warnings.
