------- Comment #6 from fxcoudert at gcc dot gnu dot org 2005-12-09 09:28 ------- Changed the title of the PR to the more general "Performance of formatted output". My experience is that using sprintf to output float values is where performance could be gained (computation of the logarithm of the written value is done twice, for example). *But* that would require a home-made floating-point I/O system, which is far from trivial to implement.
Oh, I'm also switching priority of this to enhancement, since we don't perform too bad (20% slower than Intel, 100% slower than g77) and formatted I/O isn't usually done on very big arrays. -- fxcoudert at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|normal |enhancement GCC target triplet|ia64-unknown-linux-gnu | Last reconfirmed|2005-09-24 05:35:49 |2005-12-09 09:28:43 date| | Summary|Performance regression in |Performance of formatted |formatted output vs. g77 |output http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20278
