[LLVMdev] JIT and libgcc_s.so

[James Molloy]

Hi all,

There are symbols in libgcc (and compiler-rt) that JIT-compiled modules
may need. These are currently linked correctly because lli and friends
are linked against libgcc_s.so (i.e. shared library version of libgcc,
so dlopen/dlsym works).

However if a consumer links statically, dlsym won't find all compiler
required functions (only the ones that were required by the JIT-compiler
itself will be linked).

So the question is, do we want to support users of the MCJIT linking
statically to libgcc/compiler-rt? Or explicitly not handle this
use-case?

Cheers,

James
