[Q3] Is the source code of Spacemit's gcc available

only thing added was assembler support, i.e. changing binutils. The

Oh well.

That "No." is a GPL violation right there, as I understand it. Can
the Chinese original be read as "GCC is unmodified from the GNU
version" or are they attempting to minimize the fact that they
distribute a modified *compiler*?
The latter one I think. "didn't make a lot of changes" = "made some
changes".
Right...
GNU binutils is another package, but could be conflated as part of
GCC because GCC uses binutils to generate binary output, and binary
distributions of GCC therefore normally include binutils.
This leads to a possible scenario: they are distributing a build of
unmodified GCC with their patched binutils bundled. Is the promised
binutils patch available?
No, there is simply no source tarballs or patches for the binaries
(gcc+binutils) they distribute.
So then we run down the details according to
<URL:https://www.gnu.org/licenses/gpl-violation.html>:
* the precise name of the product
* the name of the person or organization distributing it
* email addresses, postal addresses and phone numbers for how to
contact the distributor(s)
* the exact name of the package whose license is violated
* how the license was violated
You have the first two of those; I believe Martin Guy found at least
some email addresses; our discussion seems to indicate that we are
looking at GPL violations on both GCC and GNU binutils; and of course,
the sources are completely missing.
