The driver behaves differently when I run it by specifying absolute path than when I run it with relative path. See example Relative: i00202 at ubuntu:/tmp$ mcc16 --save-temps -dry-run hello.c./clang-cc -I ./include -triple=pic16- -emit-llvm-bc hello.c -o hello.bc-pqDR1Y llvm-ld -link-as-library hello.bc-pqDR1Y -o tmp.bc-M1Rwip llc -march=pic16 -f tmp.bc-M1Rwip -o tmp.s-DcVczP gpasm -I ./inc

Either always run the driver via an alias, or edit lib/CompilerDriver/BuiltinOptions.cpp: cl::opt<SaveTempsEnum::Values> SaveTemps ("save-temps",

I found out the problem. Looks like I can not rely on argv[0] to contain the full path of the executable always. Can I rely on: static Path GetMainExecutable(const char *argv0, void *MainAddr); is it Cross-platform? What to pass for second parameter here. C++ forbids taking address of "main", and the "Main" of CompilerDriver is in a shared object here. - Sanjiv Sanjiv

Hi Mikhail, Thanks for your wonderful help so far. I have few more questions to ask: How do I modify the driver to pick tools from where the driver itself resides, rather than from the PATH? And how to make sure that we have same behavior on Windows as far as paths (/ Vs \) and picking up tools from the driver directory is concerned? Do I need to write some C++ code to customize such

Yes, this is what hooks are for.

This should work: $ cd $LLVM_DIR/tools/llvmc/examples/mcc16 $ make If you're building from some other dir, you'll need to update mcc16/Makefile, so it knows where Makefile.common is located. > There are so many confusing things there: driver, plugins,

In that case, copy $LLVM_DIR/tools/llvmc/example/mcc16/Makefile to $LLVM_OBJ_DIR/tools/llvmc/example/mcc16/Makefile and build from that directory.

Dear all, I have a function that predicts DV based on one predictor pred: pred<-c(0,3000000,7800000,15600000,23400000,131200000) DV<-c(0,500,1000,1400,1700,1900) ## I define Function 1 that computes the predicted value based on pred values and parameters a and b: calc_DV_pred <- function(a,b) { DV_pred <- rep(0,(length(pred))) for(i in 1:length(DV_pred)){ DV_pred[i] <- a *
