ARM32 support

[ditek]

Request to support ARM32 platform.

ARM64 was added in #118 and there are many comments on that issue about Raspberry Pi and ARM32, so I thought there should be a separate issue for that.

[githubrobinlu]

Request to support MIPS too.

+1 for this. I think the lack of a debugger on ARM32 is what is preventing a lot of devs from using go for embedded programming

+1 Would very much like to debug directly on the RPI-32 with VSCode Remote server and Delve

What are the required steps to port a new architecture? Is the current ARM 64 code in pkg/proc/native a good starting point in this case? I'm asking because I might try to port it in the next days

[efancier-cn]

+1 , really need it on ARM 32

[shytikov]

Would like to add my voice to army of people who really longing for ARM32 support!

[zachpanter]

+1, this would be immensely helpful.

Just got a Raspberry Pi 400 and it looks like Go development will be hindered by this 😞

I switched to the 64bit build of raspberry pi os - https://downloads.raspberrypi.org/raspios_arm64/images/ and ( with a pi4 ) am able to remotely debug just fine...

Any movement on this? Like others in this thread, I am keen to use Delve on Arm 32

[pgeiem]

We are also really interested to use Delve on Arm32. Any news regarding this ?

I'm successfully remote debugging on a raspberry pi zero running raspbian (ARM 32) using puppywang's code https://github.com/puppywang/delve. I know issues have been brought up with this (mostly a lack of testing methodology), but it seems to work for some people.

I am voicing my support for this. :heavy_plus_sign: :one: In case @puppywang hadn't seen it BountySource is at 800$

[wlanboy]

Would like to support this too. Would allow me to debug golang nativeliy on my Raspberry Pi 400.

[efancier-cn]

The request has been here a while, anyone knows any update on this?

+1, would be helpful

I have looked into puppywang's code and fixed some problems. With this changes the debugger looks quite stable and I am able to debug the debugger on my Raspi. Unfortunatly the code is still not good enough to be merged. Here is my branch.

@HM4704 Hi, what exactly would be necessary to add to the branch you're pointing to?

[HM4704]

@https://github.com/parvit You can make a PR which I would merge.

[parvit]

@HM4704 I'm sorry i meant a different thing: i wish to know what kind of changes remain to implement in your branch for merging into the main.

[HM4704]

@https://github.com/parvit It has been a while since I looked into it but here are the problems I remember:

• a lot of unit tests still fail and/or are disabled for ARM. Try to fix as many as possible.
• I have marked oode parts I was not sure what todo with "Todo" or "//??". Decide what todo there.
• one unit test especially, TestContinueMulti(), bothered me alot. I spent days to fix it but I did not succeed in the end. I stll think the problem with this test is the flushing of the cpu caches after setting/removing the software breakpoint. I tried different approaches but none worked reliably. With a hardware debugger one could perhabs seee what is going wrong there but i do not own one.
• clean up the code
