A few days ago, Christophe Riccio tweeted a link<\/a> to a pdf<\/a> that shows the level of support for “Modern C++” standards in four C++ compilers: Visual C++, GCC, Clang, and ICC.<\/p>\n

One of the things I wanted to see was not just how support had advanced between versions of each compiler, but how compilers had changed relative to one another over time. I extracted the numbers for C++11 from Christophe’s document, found the release dates for each compiler, and created a chart that puts it all together.<\/p>\n

It’s interesting to see how far behind Clang starts in comparison to the others, and that it ends up in a close dance with GCC on the way to full C++11 support. It also highlights how disappointing VC++ has been in terms of language feature advancement — particularly when VS2010 was ahead of Clang and ICC for C++11 features.<\/p>\n

Creating the chart also served as an opportunity to play around with data visualization using\u00a0Bokeh<\/a>. As such, you can click on the chart above and you’ll see a version that you can zoom, pan, and resize (which is only a small part of what Bokeh offers). I intend to write about my experiences with\u00a0Bokeh at a later date.<\/p>\n

Release dates for each compiler were taken from the following pages:<\/p>\n
