From 5a6b9a27fdb2ac66aaadd90b15b1889fea8f08d0 Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Thu, 20 May 2010 14:29:43 -0700 Subject: Avoid printing a space at the beginning of lines in the output. This fixes more differences compared to "gcc -E" so removes several cases of erroneously failing test cases. The implementation isn't very elegant, but it is functional. --- glcpp-lex.l | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'glcpp-lex.l') diff --git a/glcpp-lex.l b/glcpp-lex.l index 8e3ab661e6..13e4d6f0ef 100644 --- a/glcpp-lex.l +++ b/glcpp-lex.l @@ -173,7 +173,12 @@ TOKEN [^[:space:](),]+ } \n { + /* XXX: Printing here (rather than in a parser production) + * *and* frobbing a bit of the parser state here are both ugly + * things.
