Re: [Valgrind-users] [Valgrind-developers] tilegx ?

Using SETI (Search Extra Tile-gx Information) I tried to find some recent news about tile-gx, such as a newer version of the instruction set, or new processor models or whatever indicating a sign of active development life. I find nothing. To the contrary, what I can find is that the tile-gx architecture is being replaced by tile-mx, which is an ARM based chip. See a.o http://www.mellanox.com/repository/solutions/tile-scm/ and http://www.bdti.com/InsideDSP/2015/03/03/EZchip and various other things such as ezchip roadmap. So, no developer, no user, no company person telling anything, and public information telling the chip will be replaced. So, it looks clear that tile-gx will have to be removed sooner or later. IMO, sooner is better: I spent some effort even very recently on the tile-gx files (as part of a factorisation effort) and it looks like this (evening/week-end) effort was just spent for nothing, while some real users have to wait because their wishes are just put in my TODO list. The above is some additional info for the discussion we can have at FOSDEM2017 valgrind BoF. Maybe we will receive some information from Mellanox before FOSDEM in the meantime. But with the current info, it looks doubtful anybody wants to spend any more effort on maintaining this.
