<p class="MsoNormal"><span style="font-size:11.0pt">Clang appears to always use name as specified on the command line, whereas gcc uses the name as specified in the first linemarker when compiling a preprocessed source. If I use a temporary preprocess file
during my build process, the name of the temp file is embedded into the object file. Is this a by-design behavior? Thanks!<o:p></o:p></span></p>
