xo/xo.c#L99: add missing UNUSED marker for all unused flags

[pstef]

int lflag UNUSED = 0;
int hflag = 0, jflag = 0, tflag = 0,
zflag = 0, qflag = 0,

are all set but not used, however only lflag is marked as such. Compilers complain :(

Yup, there are all ignored and should be marked as such. Here’s a patch:

diff --git a/xo/xo.c b/xo/xo.c index 6d45c9c..e682cbf 100644 --- a/xo/xo.c +++ b/xo/xo.c @@ -95,9 +95,10 @@ static xo_ssize_t formatter (xo_handle_t xop, char buf, xo_ssize_t bufsiz, const char *fmt, va_list vap UNUSED) {

• int lflag UNUSED = 0; / Parse long flag, though currently ignored /
• int hflag = 0, jflag = 0, tflag = 0,
• zflag = 0, qflag = 0, star1 = 0, star2 = 0;
• / printf-style formatting flags, currently ignored /
• int lflag UNUSED = 0, hflag UNUSED = 0, jflag UNUSED = 0,
• tflag UNUSED = 0, zflag UNUSED = 0, qflag UNUSED = 0;
• int star1 = 0, star2 = 0; int rc = 0; int w1 = 0, w2 = 0; const char *cp;

Could you please let me know the compiler/version that is failing?

Thanks, Phil

The patch looks good to me, but I didn't test it. Sorry, I didn't mean to suggest that a compiler is failing. clang/llvm 13 was recently imported into base and by default it warns about variables set but not used.
