MapReduce.R
regexp.Rdb  - use GCCTU to read regex header files. Switch to RCIndex.


FAILS
sampleCSV1.Rdb - can't find a variable named ptr when compiling, i.e. the variable is not in the R code, 
          but in the compilation unit.
          We have line as a global variable, but we need `ptr` to be a global variable that points to that.
globalStringVar.Rdb - type issue for global variable. String versus array!
trycpp.R - seg faults in createTargetMachine()



RUNS
dnorm.Rdb - segfaults on createLoad()
distance.Rdb - bad signature of call.   Needs .integerLiterals = FALSE.  Check results
proxyFuncs.Rdb - 
fgets.Rdb
sampleCSV.Rdb - doesn't actually run the compiled code.
fuseLoop.Rdb - needed the module to be the same when compiling Dnorm and Dnorm_v in the second half of the document.
backend.R - trivial - just calls parseIR() and showModule()
fuseLoop.R
fib.R
fopen.R - simple proxy
constArg.R - but the onlyReadsMemory() is TRUE before we set it.
globalString.R
simpleGlobalString.R
loop.R
testDoubleSet.R
testSEXP.R - simple allocation of a SEXP and return it. 
distance.R - just defines R functions
testDist.R - all R code. Timings for Dist().
tmp.R - just defines R functions makeCall, writeMapCall

sampleCSV.R - just defines functions

sapply.R - wrong type in a CallInst. Uses RLLVMCompile.  Looks like the compiler is 
    allocating an VECSXP (list) rather than an INTSXP (integer) and then calling
    SET_VECTOR_ELT().  But it would need to create a SEXP rather than insert the int.
  NOW: Failing on INTEGER(r_ans)[i] - can't get the type.
    Can get around this by computing INTEGER(r_ans) outside of loop. But need to deal with it generally.



BAD tests
manualFib.R - bad test as no if statement
