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

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.

Consider the example command line below $ llvm-ld -disable-opt hello.bc -l std -o hello.out Why does -disable-opt links in all the bitcode from the libstd.so into hello.out? - Sanjiv

Hi, Apparently, there is no explicit support for ISRs in the llvm framework. I could not find a matching attribute that can be used to mark a function as an ISR, which codegen and optimizer can use accordingly. ISRs aren't called explicity from any function, so currently the optimizer deletes them. We are planning to introduce a new "interrupt" attribute (to be modeled similiar to

But why the cmp libcalls have to return a 32-bit value. e.g. Our libcall for comparing two floats is char _eq_f32 (float a, float b); rather than long
