Operation
RptEnd as repeat end instruction, and 8-bit
immediate data #imm as number of repetitions.
This macro is extended to three instructions:
LDRS, LDRE, and SETRC which are converted
correctly.
Specifies RptStart as repeat start instruction,
RptEnd as repeat end instruction, and the [11:0]
bits of Rm as number of repetitions. This macro
is extended to three instructions: LDRS, LDRE,
and SETRC which are converted correctly.
