That might be > better than this PR... The project is 200k lines of template heavy C++. Not exactly a smaller testcase. I occasionally filed reports for cases where compile time exploded (and these were fixed mostly), but the general trend of 3.3 being (more than) twice as slow as 2.95 for example is unchecked, and I don't have a simple testcase for that, unfortunately. In fact, there are testcases already around: the automatic SPEC testers also log daily compile times for fixed programs. Every once in a while someone notices that something gets slower and sometimes even can point to a particular patch, but the general trend is not broken by that. > > So what should we do? > > ...which I agree to close. I'll do it, but only with a certain amount of reluctance :-( W. ------------------------------------------------------------------------- Wolfgang Bangerth email: bangerth@ticam.utexas.edu www: http://www.ticam.utexas.edu/~bangerth/
