Hi!

I think this is another fallout of the cppcheck silencing:

This is from gcc76 (cfarm machine), you can find the full build log
here:
http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=19332
http://toolchain.lug-owl.de/buildbot/deliver_artifact.php?mode=view&id=69223

While the "missing initializer" warning is actually wrong, it's right
that there are braces missing around the char[] initializer:

 383 struct s3_score_it
 384 {
 385   char name[s3_INSN_NAME_LEN];
 386   bfd_vma instruction;
 387   bfd_vma relax_inst;
 388   int size;
 389   int relax_size;
 390   enum score_insn_type type;
 391   char str[s3_MAX_LITERAL_POOL_SIZE];
 392   const char *error;
 393   int bwarn;
 394   char reg[s3_INSN_NAME_LEN];
 395   struct
 396   {
 397     bfd_reloc_code_real_type type;
 398     expressionS exp;
 399     int pc_rel;
 400   }reloc;
 401 };
[...]
4492   struct s3_score_it inst_main = { 0 };


A similar error (though due to a bogus warning) is generated for tic6x
(see
http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=19186
and
http://toolchain.lug-owl.de/buildbot/deliver_artifact.php?mode=view&id=67284):

Thus is suggest:

gas/
	* config/tc-score.c (s3_do_macro_bcmp): Don't initialize variable.
