./mul_mdmd_md.c:343: error: unable to find a register to spill in class âAD_REGSâ
Compile with -da, look at the .greg dump file, it will have a bunch of messages saying "reloads for insn ...". Find the one for the insn that is failing. Look at the .lreg dump to find the pre-reload version of the insn. These two pieces of info together should give you a clue where to look next.
