|
|
|
+ * ColdFire - supports standard bset/bclr/bchg with register operand only
|
|
|
+ * 68000 - supports standard bset/bclr/bchg with memory operand
|
|
|
+ * >= 68020 - also supports the bfset/bfclr/bfchg instructions
|
|
|
+ *
|
|
|
+ * Although it is possible to use only the bset/bclr/bchg with register
|
|
|
+ * operands on all platforms you end up with larger generated code.
|
|
|
+ * So we use the best form possible on a given platform.
