If you take a look at
void PrintPreprocessedAction::ExecuteAction() {
...
while (next < end) {
if (*cur == 0x0D) { // CR
if (*next == 0x0A) // CRLF
BinaryMode = false;
...
The value of this BinaryMode reflects whether the line ending style of the
input file
is CRLF or LF. And it is passed all the way down to the constructor of
raw_fd_ostream,
std::unique_ptr<llvm::raw_pwrite_stream>
CompilerInstance::createOutputFile(...) {
...
if (!Binary || OS->supportsSeeking())
return std::move(OS);
auto B = llvm::make_unique<llvm::buffer_ostream>(*OS);
...
So I think the line ending style of the input file does affect whether the
output is buffered.
