A couple of patches that I’ve noticed on various mailing lists –
libspe – Some small changes, but includes spe_image_open_library() to load an spe image from a ppe shared library.
binutils – “Also, if DLL’s were supported on SPU…” Interesting idea – will have to wait to see what comes of it.
gcc – Support non-constants as the second argument of __builtin_expect. Interesting idea.
(Also, Revital Eres’s function partitioning patch has had some activity, and there’s the odd patch from Alan Modra on overlays and software icache.)
