<h2>Profiles</h2>
<p>
  Each link below displays a global profile in zoomable graph form as
  produced by <a href='https://go.dev/blog/pprof'>pprof</a>'s "web" command.

  In addition there is a link to download the profile for offline
  analysis with pprof.

  All four profiles represent causes of delay that prevent a goroutine
  from running on a logical processor: because it was waiting for the network,

				prog.Reg = p.getRegister(prog, op, &a[2])
				prog.To = a[3]
				break
			}
			if arch.IsARMMULA(op) {
				// All must be registers.
				p.getRegister(prog, op, &a[0])
				r1 := p.getRegister(prog, op, &a[1])
				r2 := p.getRegister(prog, op, &a[2])
				p.getRegister(prog, op, &a[3])
				prog.From = a[0]
				prog.To = a[3]
				prog.To.Type = obj.TYPE_REGREG2
				prog.To.Offset = int64(r2)
				prog.Reg = r1
				break

This directory is the copy of Google's pprof shipped as part of the Go distribution.
The bulk of the code is vendored from github.com/google/pprof and is in
../vendor/github.com/google/pprof.

Two important notes:

1. Using github.com/google/pprof directly (for example, after installing
with "go get") should work with Go programs, but we cannot guarantee that.
What we test is that the "go tool pprof" shipped with each Go release works
