From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug preprocessor/67266] Use of "cpp -P ..." collapses multiple blank lines Date: Wed, 19 Aug 2015 01:27:00 -0000 [thread overview] Message-ID: <bug-67266-4-qpzlI7jsmS@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-67266-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67266 --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- From https://gcc.gnu.org/onlinedocs/gcc-5.2.0/cpp/Preprocessor-Output.html#Preprocessor-Output : The output from the C preprocessor looks much like the input, except that all preprocessing directive lines have been replaced with blank lines and all comments with spaces. Long runs of blank lines are discarded. -P does not change that. You might want to look into using -tranditional-cpp also because if you are using preprocessor for other than C, # might be treated not like what you want it to be treated
