------- Comment #116 from rguenth at gcc dot gnu dot org 2010-03-27 11:14 ------- Given that parsing takes most of the time the compile-time indeed looks reasonable. That DF uses >20GB of ram at -O3 is still unfortunate, but the -O1 numbers look indeed good.
I wonder if the parsing numbers are accurate as the initial report has like 9s parsing while the current ones are >200s. Can you explain that difference? (like, were you testing different source?) As is the testcase(s) are an interesting source of information - maybe we should gather those up on a page in the wiki just in case we end up closing this bug at some point (I suggest not to at the moment, the parsing times look odd and >20GB memory use doesn't sound reasonable). Did you ever test other compilers and see how they perform with respect to memory usage and compile time? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26854
