<pre>This is extracted from some (hairy) code in lldb. It looks like the tool
mistakes #x for a preprocessor directive.
=====
$ cat a.cc
#define FOO(x) { #x, asodgoasigosiangoisdangoisandgion,
sagoingsodingsoisnoisgnogsiansg, asgdoingsoadiisgadnosgidnsgioa }
#define FOO(x) { x, asodgoasigosiangoisdangoisandgion,
sagoingsodingsoisnoisgnogsiansg, asgdoingsoadiisgadnosgidnsgioa }
$ clang-format /tmp/a.cc
#define FOO(x)
\
{
\
#x, asodgoasigosiangoisdangoisandgion, sagoingsodingsoisnoisgnogsiansg, \
asgdoingsoadiisgadnosgidnsgioa
\
}
#define FOO(x)
\
{
\
x, asodgoasigosiangoisdangoisandgion, sagoingsodingsoisnoisgnogsiansg,
\
asgdoingsoadiisgadnosgidnsgioa
\
}
=====
The second macro also looks suboptimal (I would've expected the second line to
be aligned to the same column as "x"), but at least it's valid code...</pre>
