Before patch... Tue Mar 28 23:06:11 EST 2006 The following file will take roughly 10 minutes to compile Tue Mar 28 23:06:23 EST 2006 Tue Mar 28 23:25:00 EST 2006 After patch... Tue Mar 28 23:26:00 EST 2006 The following file will take roughly 10 minutes to compile Tue Mar 28 23:26:12 EST 2006 Tue Mar 28 23:27:03 EST 2006 This is on a dual 2.0GHz G5 with 2 Gb of RAM. However I don't see any significant impact on the compile time for the aermod polyhedron benchmark. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21130
