Is it possible to generate flamegraphs for the `build.rs` of a crate? This could be useful for debugging the long execution of a build script (Ex. multiple calls to `bindgen`, `cc`, etc)

There's a lot of low hanging fruit that can be done in terms of performance improvements.
- Decisions need to be made as to whether we want to use Criterion, or the native `cargo-bench` suite, curren…

Similar to #8, this would be an option to draw the flamegraphs in the sunburst layout (radial coordinates).
First use of it I think came from here by @paulirish: https://bugs.chromium.org/p/chromiu…

We've been trying to profile our `fluentd` process due to high CPU usage, and our flamegraphs show that many of the profiles only show `C function`. It would help if the debug symbols were uploaded wi…

E.g. if a frame couldn't be inlined because it hit `MaxInlineDepth`, that info could be somehow annotated graphically i…

Hi, I am trying to profile a VM (host+guest) with `perf kvm` by generating call graphs, I run into a couple of problems with `perf kvm` and `flamegraphs`.
With v4.18 kernel, it seems that the outp…
