title: Line by line profiling of a C++ program in linux, and being able to integrate in eclipse?
body: <p>We have a project, we've being testing which involves a fair amount of math (including linear algebra, massive matrix manipulation, sparse matrices, openblas, armadillo library etc)</p>
  
  <p>I asked this question because all related ones are really old. But how can I profile my project line by line so as to locate bottlenecks and find ways to ease them? Are there any new tools for that? I would also love it if the tool could integrate with Eclipse on linux.</p>
