From 847e697a240e6d30335335c62084743978fa2084 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 17 Oct 2011 09:59:40 +0000 Subject: Support -fdebug-cpp option This patch adds -fdebug-cpp option. When used with -E this dumps the relevant macro map before every single token. This clutters the output a lot but has proved to be invaluable in tracking some bugs during the development of the virtual location support.
