At some point I thought I tried to include spr_tcg.c.inc before that function and the compilation failed, so I decided to include it where translate_init.c.inc was included.

Making the spr_noaccess function not static, and moving the define to
internal.h is required, otherwise the project doesn't build

Why is that?  You're moving the code to a different file, but then including that file back into the same translation unit.  There should be no change in which symbols appear in which object file.

I think that the spr_noaccess move might be required by patch 7, but that's something different.

ah, yes, forgot to specify why. gen_op_mfspr uses SPR_NOACCESS on line 4284. At some point I thought I tried to include spr_tcg.c.inc before that function and the compilation failed, so I decided to include it where translate_init.c.inc was included. I think it was another function that was declared later, but can't remember which

Testing now I verified that I can include it there, so I will do it and delay the move to patch 7, no problem
