llvm dev - Apr 2016 - lli size

Hey there,

Been googling but can't find.  Thought to ask the wizards.

The LLVM interpreter.  I am creating a simple wrapper around it to run
a script.  The program after linking is about 25 megs stripped of
debug symbols.

This seems a bit large.


Is it possible that this could somehow to be drastically reduced?
Is it worth going and trying to rip things out?

The code which instantiates the interpreter is here:
https://github.com/timprepscius/llvmscriptdemo/blob/master/src/llvmscriptdemo.cpp


Any help/advice/etc, greatly appreciated.

-tim

I have been able to get the executable down to 7 megs.

By:
   auto ee = llvm::Interpreter::create(std::unique_ptr<Module>(mo));

and changing the linker flags.

I would like to get it down to a meg or less.

This is for a release build of LLVM?
or a debug build?

Hi

Not sure what your use case is but you might be interested in VMIR -
https://github.com/andoma/vmir

VMIR does bitcode interpretion of bitcode and
suboptimal-but-better-than-nothing-JIT on ARM

The stripped binary is around 170kb on x86_64. It's still in its early
stages so it might not
suit your needs but, as the README says, it can run all of the gcc-torture
tests at all opt-levels.

You can contact me off-list if you want to know more.
