<pre>Hello,
I have encountered a bug in clang-format-11.0.0 (valid at least for v10 too)
Default configuration with
"AlignConsecutiveMacros = true"
"IndentPPDirectives = BeforeHash"
When there are #define blocks in an #elif/#else branch and there is a comment
in between #define blocks, all #defines, their values and comments are aligned
based on the last block, which is incorrect. If the comments in between the
blocks are removed or the blocks are in an #if branch, this error does not
occur.
Example how it looks:
#if defined(SOMETHING)
#elif defined(SOMETHING_ELSE)
// A comment.
#define a 1 // A comment.
#define b 2 // A comment.
#define c 3 // A comment.
// A comment.
#define aa 1111 // A comment.
#define bb 2222 // A comment.
#define cc 3333 // A comment.
// A comment.
#define aaaaa 111111 // A comment.
#define bbbbb 222222 // A comment.
#define ccbbc 333333 // A comment.
#endif
This is how it should look:
#if defined(SOMETHING)
#elif defined(SOMETHING_ELSE)
// A comment.
#define a 1 // A comment.
#define b 2 // A comment.
#define c 3 // A comment.
// A comment.
#define aa 1111 // A comment.
#define bb 2222 // A comment.
#define cc 3333 // A comment.
// A comment.
#define aaaaa 111111 // A comment.
#define bbbbb 222222 // A comment.
#define ccbbc 333333 // A comment.
#endif
Best regards</pre>
