63 immediately discarding (but counting) those exceeding the maximum
64 possible amount. Track whether output and input operand counts ever

67 the first operand.

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

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