Not yet: I thought I should at least ask for the source code before 
reporting it to FSF. But unfortunately I can't find any email address or 
postal address or phone number to contact them...

On the other hand, I found a forum topic related to it [7]:

(a rough translation from Chinese)
[Q3] Is the source code of Spacemit's gcc available
[A3] No. But [we] didn't make a lot of changes on gcc, basically it's 
[the same as] the open source (sic.) version. After all, the only thing 
added was assembler support, i.e. changing binutils. The patches 
supporting the instruction will be ready to be released, so that 
everyone who build their own toolchain can also patch [it] themselves.

Oh well.
