I'm having a lot of fun (not) right now trying to write some 64-bit ARM assembler (for iOS). The clang inline assembler is really terrible and there's almost no docs (for ARM-64).

Is there a chance FASMARM will support 64-bit?

Yes.

OK, I guess I should have asked: "If it will support 64-bit, when can we expect it to be available" ?

I have no fixed date. When I get free time I work towards it. My current work schedule is very full so right now it is on hold.

OK, thanks; I wish it were available right now

Me too.

Hi revolution, & hi ronware, thanks for starting this thread!
I hope you are both doing well =D

You might have heard the Raspberry Pi 3 has a 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU.
This will be the 1st R-Pi with aarch64 support, & will be my 1st opportunity to program aarch64.
I will be getting my R-Pi 3 soon, & all of my bare-metal examples for R-Pi 1 & 2 use FASMARM:

I have explored stuff like SMP & NEON on R-Pi 2, & VFP on the single core R-Pi.
Also I have made a nice start to understanding the Broadcom GPU, with demos displaying all the primitive types on screen.
The R-Pi 3 uses the same GPU, & is the 1st to clock the GPU up to a higher frequency too!

I would love to convert all these demos to run on the R-Pi 3, & would love to learn aarch64 at the same time!

I do not know how far you are with the aarch64 support in FASMARM, but I would love to help out in any way I can.
I could do testing, or help you program in the full instruction set.

P.S I also started a Game Boy Advance github repo using FASMARM, with some fun examples:

Anyway good luck, & thanks again for such a great ARM assembler.

Now done.

v1.39

Wow thanks so much revolution =D
