Subject: Fix a pretty big but subtle bug counting the number of newlines to emit.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5c0887c1be978f4288cba5afcf93d0bdf2bd22f5;p=clang

Fix a pretty big but subtle bug counting the number of newlines to emit.
This would cause us to emit different code (in -E mode) for these two files:

---
#define t(x) x

t(a
3)
---
#define t(x) x
t(a
3)
---

In one case, -E would print "a\n3", in the other it printed "a3".  Now
it prints "a3" for both.

This is part of PR1848.
