using GNU m4 instead of custom perl scripts would be a good option.. I too
faced a similar issue and did something like this for RVCT compiler, 


extern "C" { 
          $1 JITStubThunked_$2(STUB_ARGS_DECLARATION); 

    str lr, [sp, #0x1c]; 
    bl __cpp(JITStubThunked_$2);
    ldr lr, [sp, #0x1c];
    bx lr;



After that, just ran m4 tool over the source code to get automatically expanded

Just sharing here so since this fix looked simpler and effective.
