             Bug #: 11452
           Summary: Line splicing in MSVC compatibility mode
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: eremeev at viva64.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Source lines followed by a backslash (\) and a newline immediately after it are
spliced by clang. In case of the following:

int Test(int a, int b) \
{int c = a + b; \
    return c;\
}

It will be preprocessed by clang as:

int Test(int a, int b) {int c = a + b; return c;}

MSVC preprocessor behaves differently and will splice the lines only inside a
macro definition. The code example above will not be joined into a single line
by MSVC preprocessor.
