following examples:
CASE 1: 1 Repeated Instruction
LDRS RptStart0+8;
LDRE RptStart0+4;
SETRC RptCount;
- - - -
RptStart0: instr0;
RptStart: instr1; Repeated instruction
instr2;
CASE 2: 2 Repeated Instructions
LDRS RptStart0+6;
LDRE RptStart0+4;
SETRC RptCount;
- - - -
RptStart0: instr0;
RptStart: instr1; Repeated instruction 1
RptEnd: instr2; Repeated instruction 2
instr3;
CASE 3: 3 Repeated Instructions
LDRS RptStart0+4;
LDRE RptStart0+4;
SETRC RptCount;
- - - -
RptStart0: instr0;
RptStart: instr1; Repeated instruction 1
instr2; Repeated instruction 2
RptEnd: instr3; Repeated instruction 3
instr4;
