Hi! I'd like to backport the "asm inline" series to 8 branch and 7 branch. The patches are identical to trunk, except I added a patch 8/8 that makes these branches not error on code it only warned on before (that is, C code that uses restrict or const as asm qualifier).
The 7 backport has a context change in tree-inline.c, but everything else is identical. The goal of backporting is that users (Linux, mostly) can start using it sooner. Is this okay for 8? Is it okay for 7?
