How to write buffer contents to command, and read results back from its stdout to a new buffer

Question

I am editing C source code in vim. I'd like to:

1. Write current contents of the buffer (which is potentially a scratch buffer) to my favorite C compiler's stdin (essentially, pipe buffer to a command)
2. Read from the pipe (that potentially reads stderr as well, because compilation may fail), and pipe compiler's stdout to a new buffer/split in vim
3. (Optionally) set the new buffers filetype to whatever I specify (generally assembly)

I'd prefer vsplit, instead of a new buffer, but I don't know whether that's possible. I am not an expert in vim. I have found this, and this answers. The latter one is closest to what I desire. It uses a temporary buffer as far as I understood; is possible to do the same thing without temporary files, but directly dealing with stdio? If not, I'll go ahead and use it.

Like most things, there’s already a plugin for this.

You may be able to configure it to split vertically, but the output window is persistent, so you can just alter the window arrangement to your liking after the first run.
