i've found emscripten uses `lli` tool (gen_struct_info.py):
# NOTE: We can't generate an executable in the next step because it won't
run on the current system without changing the target.
# If we change the target, some type sizes will change resulting in wrong
data. As a workaround, we will be generating bitcode and
# run that with the LLVM interpreter. That way we can use the default
target and still run the code.
Can anybody please explain to me that hack? Can we avoid using lli tool
(probably do the same in python script or in js)?
The problem is that on some platforms (ios f.e.) lli can't work because of
exception:
"args": [
"lli",
"/private/var/mobile/Applications/10BD667C-339F-4A25-B6BF-D5404F079E5C/tmp/tmpOpO_KF.ll"
raises exception in ExecutionEngine in :
return runFunction(Fn, GVArgs).IntVal.getZExtValue();
exc_bad_instruction (code=exc_arm_undefined, subcode=0xf4cffce8).
Same unresolved issue in llvm:

Any thoughts are highly appreciated.
