How would one go about automatically identifying lines of C++ source files that contain (potentially) executable code? By potentially excecutable code, I mean code that might have been executable had its template been instantiated.
I expect it would be a purely syntactic determination. I'm not even completely sure this is even possible in all circumstances, but I guess it is.
Note that this is not the primary function of a dynamic coverage checker (although some may in fact perform this...)
(The goal is to enable a coverage checker to distinguish executable lines from comments, empty lines, type declarations, and the like.)
If you work with CLion IDE, you can use the pluging C/C++ Coverage.

are there any tools for symbolic execution on binaries. i mean using which, we do not require to modify the source code - like klee_make_symbolic
or we can do such changes in IR (llvm ir etc.)
thanks in advance
Maybe miasm can fit your requirements. It is a reverse engineer framework that supports static symbolic execution. As far as I know， it is more simple than KLEE and S2E.
Canonical list is in Awesome Symbolic Execution.
Symbolically executing binary code is much much harder, so i doubt there are such tools exist.
However note that you don't necessarily need to modify your code when using KLEE because it can model POSIX environment and C library (when compiled with support for this, of course). Using these features you can automatically symbolize argv arguments and keyboard interaction.

Is there a tool that converts C++ code into fortran? Please state any possible deficiency of the tool you use.
I know it sounds silly but I do have a C++ code that calls a big Fortran code inside and I need to to use OpenMP. I am trying to keep the parallel region only inside Fortran (because there are many COMMON blocks and EQUIVALENCEs used) so I have to translate a few hundreds of lines of C++ functions to Fortran.
Depending on the compiler (such as the GNU compilers), you're actually able to compile C, C++, Fortran, etc. code together. This is so you don't actually have to translate or rewrite that code. C++ Forum Answer

I want to write a program that runs before Visual Studio compiles my project.
It needs to extract only the types, names and parameters of all functions, classes, structs, enums my project is using from files in a specific folder (/sdk) and copy those into a new folder (/sdkmin)
So I basically want to have a program that minifies the sdk my project is using.
Is there any decent library that allows me to do that without having to write my own parser/lexer/whatever?
I think what you should do is look at some clang tools like "clang-format", "include-what-you-use", etc., which build on the clang AST front-end stuff to do various interesting things. This will provide the lexer and parser for you, which would indeed take a very long time if you started from scratch.

Recently I tried tup and I am VERY impressed by its correctness and speed, and the fact that monitoring the file system makes the tool really robust. It is also very easy to understand.
It never gets anything wrong, and when it does, it will show me. I would like to find a tool that is more mainstream and cross-platform friendly as long as it meets the requirements below.
My questions are:
Do you know any alternative build tool that has:
O(1) rebuilds.
Completely correct dependency tracking.
(Optional) Takes advantage of filesystem access.
EDIT: This is not a subjective "recommend me a tool" question, it is give me names of tools that meet these requirements because I would like to further research on how they behave for my use cases.

I am porting a large, messy, 10 year old cold base in C++ from Metrowerks on OS X to XCode. There are so many files and all the other people that touched this over the years are gone. Nobody know what files are actually needed and which are just cruft.
Is there any tool that I could run and have it produce a list of what files are ACTUALLY needed?
You could run doxygen on your project and have it generate inheritance diagrams for your classes. It can also generate caller graphs to help you find dead code.
You can try searching this static code analyzer list in Wikipedia. The ones that I've seen in actions would be cppdep and Include Hierarchy Viewer, although the first one is a little rough and the latter is a Windows analyzer only for the include tree. Also that still might not give you all the info if the dependencies are not explicit.
Edit: Also, the following StackOverflow search query seems to have results that might interest you:
