36MB is quite small already. I guess you already built only one backend? (-DLLVM_TARGETS_TO_BUILD=host) I don't think it will get much smaller.
Your requirements, however, sound like you could easily use a more specialized compiler, like TinyCC? If your project is LGPL compatible, I am sure you can make it codegen to a memory buffer. NativeJIT has good data structures for that. The bigger task then is resolving relocations and figuring out dependencies (especially on Windows). I guess you could find all that in LLVM and use it without the entire engine behind.

i want to integrate a C source JITer into my application but the resulting executables are too large
is it possible to reduce the resulting libs/exe some way? current VS2017/svn build example: llvm-build\Release\bin\clang-interpreter.exe ~36MB for now (that can change later) - i want to jit simple c-code - no std library or something - x64 only - no deep/full architecture optimization needed - no c++/templates etc. any ideas?
