Richard Earnshaw <rearnsha at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |RESOLVED Resolution|--- |WONTFIX --- Comment #17 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- OK, I've found the erratum number, it's 720247; but it's specific to the 11MPcore and is fixed in r2p1 silicon. The erratum workaround description states that there is *no* robust software fix when the MMU is disabled. Some hardware fixes on your platform might be possible, but are off-topic here. Also, using r2p1 silicon fixes the problem. Either way, there's nothing we can do in GCC to address this, given the nature of the problem.
