Cortex-A7 pipeline is non-symmetric, what does this attribute mean?
My understand is that cortex-A7 pipeline's five entries does not have the same two, in the contrary, the cortex-A15 have the two entries are the same.
You're very welcome and thanks for the link. There is hardly any details on the A7 architecture in that document.
Here is on old post that asks a similar question Cortex-a7 dual-issue? Surprisingly you can find out more details on the A7 arch from the GNU machine description file than ARM docs (I went through the whole A7 TRM and couldn't find a single reference to dual-issue apart from the disable bit in ACTLR)! The cortex-A7.md file has some insightfully comments that makes it a lot easier to decipher if you're not familiar with the syntax.
Yep that and the LLVM is where one often sees things first
I just had a look and they seem to have just made a mess of the gcc trunk as the arm and aarch64 directories have disappeared from trunk/gcc/config. Now I very much hope that is not a glimpse into the future!

I think it is unbeliveable!!!
I go to the site, there is no arm or aarch64 directories!
Sorry that was just the first page of results. Silly me. I normally sort by date and arm then normally occurs near the beginning.
Oh, no!
We are all too careless!
