------- Comment #4 from jakub at gcc dot gnu dot org 2010-09-17 07:09 ------- You can use gcc -E -P, then it doesn't print # <lineno> <file> lines and puts the label and fn on the same line (as, without the line notes locations aren't preserved anyway). As Andrew wrote, gcc -E is a C/C++ preprocessor, and the semantics of label: fn (args) is the same as label: fn (args) and the former maintains better the location info.
