Adding support as in "ignore them" would be fairly easy, but correct support is quite difficult. Per principle, valgrind has to know a) that OUT writes a byte / word / dword and that it has to check all the bits it writes for definedness (or ignore some as they don't matter depending on the port?) b) that IN reads a value and makes all its bits defined (but what if not all bits are defined?) |
