Yes, that's not unreasonable. With f2c, you could potentially get your
fortran into C, then Go asm and then call that.

Thanks @kortschak. The c2goasm project (
Hi All,
I've open sourced some work that I've done to generate Go server stubs from
OpenAPI 3.0 specifications, found here:
https://github.com/deepmap/oapi-codegen
However, I can't figure out why I can't import my code as a V2 module.
The release is tagged with v2.0.0, my go.mod file specifies

Assembly incurs a function call cost (non-inlineable AFAIU), but Cgo
incurs a function call cost with additional work for C stack and call
conventions translation as said by Tamás.

Nice! Thank you, Andrei. That looks very helpful.
Perhaps https://github.com/minio/c2goasm might be of interest.
I don't see anything in there about Fortran specifically, but I don't think
it would be a huge leap.

I didn’t mean the current code was incorrect, I meant the reason it isn’t done
as the op proposes is because of weakness in the memory model - since the store
of the done might not be visible to a read not done under lock, otherwise the
ops proposed code would work and there would be no reason f
Thank you Ian! This is so helpful.

No. The assembly function is simply called just as a Go function is called.

I am pretty sure it is the memory model unless there is other code in the
stdlib that sets the dove back to nil - which wouldn’t make sense since the
channel should be unique to the context instance and that would allow multiple
done channels to be created.

If I include a chunk of assembly .s code in my Go code, does my program pay
the CGO transition cost of locking and changing to a C stack?
I'm pretty sure the answer is no. But my knowledge of the Go internals is
low enough that I thought I would like confirm that before I go pulling in
.s code.
You have to hold the lock to read/write c.done.
Defer would do, but slow things dow.

I did a bit more digging and found this:
https://go-review.googlesource.com/c/text/+/55331/
Which states:
"language: remove manual hr -> sr mapping was removed in CLDR for
geo-political reasons"
Which answers why it doesn't work so I think it is just the example that
needs removing/updating.
Because the compiler/processor might reorder things, so the value must be
obtained while holding the lock.
This is actually a weakness due to the memory model of Go not being fully
specified IMO. If that were changed this code could probably be written as you
suggest.

The article for the golang.org/x/text/language here:
https://blog.golang.org/matchlang
states that "For a user preference of "hr" (Croatian), the best match is
"sr-Latn" (Serbian with Latin script), because, once they are written in
the same script, Serbian and Croatian are mutually intelligibl
The following code is a snippet of the context pkg.
cancelCtx.Done():
func (c *cancelCtx) Done() <-chan struct{} {
c.mu.Lock()
if c.done == nil {
c.done = make(chan struct{})
}
d := c.done
c.mu.Unlock()
return d
}
why does not return *c.done* directly like this?
func (
It clearly shows a 'chan receive' item in that trace, which is from the
<-variable part. That is the blocker.
STW pauses are rarely more than a few seconds long, and you would have to
have allocated massive amounts of memory, then stopped using it, to cause
one.
