[LLVMdev] JIT : Does it cache the compiled code of executed functions upon runFunction(..)?
Hi Gabi,
I have no idea why your performances is not as expected with such low level
of informations.
But, I know that the binary code is cached by the JIT. You can find the code
in JIT.cpp to convince yourself :
runFunction -> getPointerToFunction ->getPointerToGlobalIfAvailable which
returns the native address of the jitted function.
You can even try to measure time needed by each runFunction to run to
double-convince yourself. :)
Olivier.

[LLVMdev] JIT : Does it cache the compiled code of executed functions upon runFunction(..)?
Hello
I have the following scenario, and I am not sure why the performance
is so bad (take 30 minutes to complete with very simple generated
functions):
1. Create module
2. Do something like EE =
EngineBuilder(theModule).setEngineKind(EngineKind::JIT).create();
3. Create a function in the module: theModule->getOrInsertFunction(..)
4. Execute 1000 times the function using

[LLVMdev] 2nd attempt for a working patch for bug 2606
...tub(...) which is declared in ExecutionEngine
and overwritten in JIT (within JITEmitter file scope). Your response prompted my search. I've unit tested this and it works great.
There is one caveat though. The implementation of JIT::getPointerToFunctionOrStub(...) first invokes ExecutionEngine::getPointerToGlobalIfAvailable(...)
behavior to check whether or not the Function instance is already actualized. Subsequently JIT::getPointerToFunctionOrStub(...)
calls JITResolver::getLazyFunctionStub(...). Given that ExecutionEngine::getPointerToGlobalIfAvailable(...) iterates through all known
actualized functions, we...

[LLVMdev] 2nd attempt for a working patch for bug 2606
Hi Garrison,
I finally come back from holidays and take time to watch your patch.
I must say that I largely prefer this version over the previous one ! I like
the reuse of getLazyFunctionStub, but I don't know if the
forceEmitFunctionStub is still needed ?
I thought about JIT and modules, and I wonder if we don't need to take it
another way.
Now we can create multiples JIT. What if we

[LLVMdev] 2nd attempt for a working patch for bug 2606
This is the second version of a patch, which I recently attached to bug 2606, whose original version was
modified to reflect the lists comments. Also please note the comment at the end of this email, which basically
questions whether this bug is really a bug.
1) To solve the foreign Module GlobalVariable problem, I modified JIT::getOrEmitGlobalVariable(...) to
directly attempt to map a found

I've seen OrcJit is under overhaul, and also the MCJIT, so what's the plan?
I didn't seen any roadmap and plan about OrcJit & MCJIT.
And would OrcJIT be stablize in version 7.0? Or latter version?
Would MCJIT be removed in source tree, when?

[LLVMdev] Question about memory allocation in JIT
Hello! Working with LLVM JIT-compiler I found a small bug and I'd like to correct it. Namely, on some tests LLVM fails with message "JIT: Ran out of space for generated machine code!"
This error emerges because the test creates big static array. Global variables are placed into memory block for function, that is first seen using given variable. Besides, during memory allocation

[LLVMdev] PATCH (rest of code changes) "bytecode" --> "bitcode"
Here is the bulk of the sanitizing.
My residual doubts center around the question
whether we still do/want to support (un)compressed *byte*code
in 2.0/2.1.
I need a definitive word on this to proceed.
My understanding is that bytecode is already gone, but there are
still some functions/enums that really deal with *byte*code
(instead of *bit*code).
I did not touch those areas, so the attached
