58 immediately discarding (but counting) those exceeding the maximum
59 possible amount. Track whether output and input operand counts ever
60 matched, and use this to better indicate which of the operands/

62 the first operand.

80 point names. Check that entry points aren't defined, yet. Clear
81 unwind.prologue, unwind.body, and unwind.insn.
82 (dot_body): Call in_procedure. Check that first directive in procedure
83 had no insns emitted before. Set unwind.body.
84 (dot_prologue): Call in_procedure. Check that not already in prologue.
85 Check that first directive in procedure had no insns emitted before.
86 Clear unwind.body.

97 insn required to be last in its group but the required slot hasn't
98 been reached, yet. Allow conversion from MII to MI;I for bundle
99 consisting of only 2 insns with the stop between them. Suppress
