Now it reports the correct device and memory usage rather than "Unknown":

$ avr-size --format=avr --mcu=attiny1614 example.elf
AVR Memory Usage
----------------
Device: attiny1614

Program:    1420 bytes (8.7% Full)
(.text + .data + .bootloader)

Data:        276 bytes (13.5% Full)
(.data + .bss + .noinit)

thanks @chenzhuoyu for the PR.

where is the patch from?

[ladislas]

this must point to the patch in this repository, not in yours

[chenzhuoyu]

Yeah... but how do I put this patch file into this repo before... well putting this patch file into this repo? Should I split this into two PRs where the first one adds a patch file, and the second one applies the patch?

[chenzhuoyu]

@ladislas I reverted the changes in avr-binutils.rb for this PR. After this PR got merged, I will open another PR to apply the patch.

[chenzhuoyu]

thanks @chenzhuoyu for the PR.

where is the patch from?

1. I noticed that the patch file applied in Formula/avr-binutils.rb is NOT the one in this repo, and they are quite different. So I replaced Patch/avr-binutils-size.patch with the one referenced in Formula/avr-binutils.rb (Is there any reasons for the discrepancy?)
2. I wrote a script to diff between the current avr-libc and avrdudes/avr-libc to find out all the newly added parts. It turns out there are 79 of them, which I listed above.
3. I wrote another script to scrape all the EEPROM / Flash / Internal SRAM sizes from each ioxxx.h for the new parts, verified some of them manually, and updated the patch file.

@ladislas Any updates on this?

[ladislas]

it's in my long long todo list, but I'm a bit overwhelmed at the moment 😓

I also don't use avr/arduino that much now, so getting the pieces to test this is not an easy task.

@osx-cross/team what's your take on this?

@chenzhuoyu give me a few more days to dive into it.
