alexcrichton opened PR #3344 from jitdump-trampoline to main:

This commit updates the jitdump profiler to generate JIT profiling
records for generated trampolines in a wasm module in addition to the
functions already in a module. It's also updated to learn about
trampolines generated via Func::new and friends. These trampolines
were all not previously registered meaning that stack traces with these
pc values would be confusing to see in the profile output. While the
names aren't the best it should at least be more clear than before if a
function is hot!

Heads up @jlb6740, since you're the original author of the VTune support: generated trampolines for calling into Wasm weren't previously being registered for profilers (see the top-level PR description) and there are some updates needed for including them in the VTune support. See the jitdump support in this PR for an idea of the kind of thing needed. I don't know exactly what is needed for VTune.
