[LLVMdev] Using a function from another module
...m trying to use a function defined in one LLVM module from another module
(in the JIT) but for some reason it's not working out. My sequence of
activity is roughly like this:
1) Create moduleA
2) Create moduleB with "func()"
3) execEng = ExecutionEngine::create(
new ExistingModuleProvider(moduleB));
4) execute "func()" (this works fine)
4) add "func()" to moduleA as a declaration (no code blocks) with External
linkage.
5) execEng->addModuleProvider(new ExistingModuleProvider(moduleA));
6) run a function in moduleA that calls "func()"...

Hi Ralf,
Your problem is that the ExistingModuleProvider takes ownership of the
Module, deleting it when it goes out of scope. You would see the same
behavior if you just offset the code with an unnamed block as shown
below. The fix is simply to leave the 'mp' variable in the caller so
it doesn't go out of scope before you're do...

[LLVMdev] Newbie JITter
...dynamically generated assembler source to machine code, and I have
that all working, copied from the llc tool and the JIT example. I
have two questions:
1. What optimization passes, if any, should I run on the module
before I pass it to the ExecutionEngine.
2. Do I need to retain the Module/ExistingModuleProvider, once I've
built the ExecutionEngine and have a Function object. Or is there
some simpler way to store/call the native code block?
An unrelated question: I want to dump the native assembler form of
the code generated by the JIT. Currently I dump it using some code I
adapted from llc,...

[LLVMdev] Running specific passes
...of some analysis, I need to change the program and then
invoke Mem2Reg pass. That pass, in turn, requires other analysis, so I must

visit(m);
ExistingModuleProvider mp(m.getParent());
FunctionPassManager pm(&mp);

Tell the EE that buffGV -> buff:
ee->addGlobalMapping(BuffGV, buff);
Then you should be good to go!

[LLVMdev] [PATCH] Prefer to use *.opt ocaml executables as they are more efficient.
I noticed that the ocaml compilation isn't using the .opt
executables if they're available. We might gain a slight
optimization in ocaml compile time by optionally using them
with this patch.
