my perl 5.10 here seems to create the %cpu when doing keys(%cpu), workaround problems because of that

Remove the unused parameter const arch_env_t *env from arch_get_irn_reg_class() and arch_irn_has_reg_class().

Remove the unused function arch_is_possible_memory_operand().  It is identical to arch_possible_memory_operand().

It does not make any sense to remove AM, which loads a non-GP value to fix register conflicts with base and index.  This situation plain does not exist.  Base and index are always GP.

vfsub and vfdiv are now commutative, because there are reversed forms of these instructions.  This enables more AM folding.

HACK: Prevent folding reload AM when the node already has a "real" memory input.  This should fix 176.gcc

[r22655]

Assert that ia32_perform_memory_operand() only tries to fold a reload into a node, which has NoMem as memory input.
