Bug ID: 33130
Summary: clang-format resets comment indentation before ifdefs
Product: clang
Version: 4.0
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Formatter
Assignee: unassignedclangb...@nondot.org

Hi,
when running clang-format over a large in-house C source base, I noticed that
it resets the indentation of comments before ifdefs to 0, although an empty
line was placed between comment and #ifdef.
(I understand that it resets the indentation to 0 if the comment is directly
before the ifdef, because then, we can assume that the comment belongs to the
ifdef)
But if there is an empty line in between, I think the comment should instead
follow the indentation from the code before the ifdef or (if unsure),
clang-format should just keep it as it was. (?)
Example:
It changes:
void f(void)
{
char c;
/* Comment */
#ifdef FOO
...
Into:
void f(void)
{
char c;
/* Comment */
#ifdef FOO
...
I am using clang-format 4.0.0 but I don't think this ever worked (tried many
versions in the past few years).
Thanks,
Clemens
