Not quite I think. The `loc`ation parameter is used under some
circumstances, though it's dependant on some #ifdefs:
78 static bool
79 avr_handle_option (struct gcc_options *opts, struct gcc_options*,
80 const struct cl_decoded_option *decoded,
81 location_t loc ATTRIBUTE_UNUSED)
82 {
83 int value = decoded->value;
84
85 switch (decoded->opt_index)
86 {
87 case OPT_mdouble_:
88 if (value == 64)
89 {
90 #if !defined (HAVE_DOUBLE64)
91 error_at (loc, "option %<-mdouble=64%> is only available if "
92 "configured %<--with-double={64|64,32|32,64}%>");
93 #endif
94 opts->x_avr_long_double = 64;
95 }
96 else if (value == 32)
97 {
98 #if !defined (HAVE_DOUBLE32)
99 error_at (loc, "option %<-mdouble=32%> is only available if "
100 "configured %<--with-double={32|32,64|64,32}%>");
101 #endif
102 }
Also, this implements the TARGET_HANDLE_OPTION function, so changing
the arguments wouldn't really work and as the `loc` argument is used
under certain circumstances, I kept it as is and marked it unused.
(Adding an #ifdef in front doesn't make the code any more readable.)
Thanks,
Jan-Benedict
