The sources were available from here
http://distribute.atmel.no/tools...
But at least for me , that link is dead
Where can i find the latest sourcecode now ???
They must publish the source according to GPL
Where is the latest avr-gcc binaries (zip) ... Think i saw them once on their site.
Maybe the source is linked from there
Wonder if they have introduced the stupid "Non optimizing" code on avr-gcc , as they had on their "Free" pic-gcc ...

Indeed though back to distribute.atmel.no that's now ERR_ADDRESS_UNREACHABLE
Microchip needs to release the source for their AVR 8-bit Toolchain 3.6.2 Toolchain.
They distribute the binaries here.
https://www.microchip.com/mplab/...
And are bound by GPL to release the source.
@the old source site , the latest release was 3.6.1 , even month after they had made their 3.6.2 avaiilable , now is the chance to release the 3.6.2 sources. 
Edit:
I have contacted Morten via PM , and asked for the source to be made available.
Hopefully he'll comment here.

MPLAB XC8 v2 for PIC is based on Clang with the benefit of the addition of C99 for PIC.

Standard for free Unlicensed (Free) versions of this compiler now allow optimizations up to and including level 2. This will permit a similar, although not identical, output to what was previously possible using a Standard license.

On the other hand, the compilers [MPLAB XC] are perfectly adequate for DIY use; ...

MPLAB XC8 v2 for AVR is based on FSF AVR GCC that has zero price optimization up to -O2 (IIRC)
Hopefully that's not the reason the source was never released 
Edit:
Seems to be a different family the XC8 compilers

To reiterate what I said in the PM, I do not know why that server is offline. Create a support requests (yes... I know) and they'll route it to the correct group.
Thanx Morten

Did make a support request , requesting the sourcecode for the 6.3.2 build:
Technical Support Case 00419028 has been created
Lets see what happens.

I have heard nothing wrt the case. And have just written in the case , asking them to release the sourcecode again.
