partout ceases to build

[Paolomio]

I have previously successfully used partout, but my project suddenly started reporting

Error: Undefined reference to '__builtin_partout'

It's a little mysterious as to why this one function cannot be found. Anyone seen something like this or have any ideas what's the matter? I can't seem to see whatever stupid thing I've done to deserve this...

Thanks,

Apart from the obvious inclusion of including xs1.h of course, are you calling partout(p,n,val) from C instead of XC?

It's none of the obvious things...it compiles but won't link, so xs1.h is indeed included, and it is an xc module. It only fails during link...

FWIW, this looks to be a compiler bug. A function containing a partout() statement compiles and links fine, as long as the statement is not also inside a thread of a multi-threaded par block. In that case, it compiles fine, but fails to link with the error noted earlier.

I've filed this as a bug with xmos. They haven't confirmed that it is indeed a bug, but it has the very distint odor, and is a repeatable error (at least by me).

Oh, yeah, FWIW I'm using 11.2.2, but saw this on 11.2 as well.
