Update to gcc6809lw patch which may help compilation of some sources
Due to persistent random compiler crashes and errors related to "M_REGS",
this patch update (4.6.4-2) essentially removes the varius constraints
allowing the "soft registers" in most operations. It was causing more
problems than it solved and it is not clear that the logic behind those soft
registers even makes sense any more.
This patch also fixes a bogus comparison related to selecting the right size
for a constant. Instead of the excessively clever comparison scheme that was
previously in use, the comparisons have been replaced with straight forward
comparisions for the top and bottom of the relevant 2's complement ranges.
