[LLVMdev] MCJIT and Lazy Function Creators
Out of curiosity, I'm replacing the JIT with MCJIT on my compiler. As
all "external" functions are provided by the language's FFI mechanism,
it does
MyExecutionEngine->DisableSymbolSearching();
MyExecutionEngine->InstallLazyFunctionCreator(&MyLazyFunctionCreator);
which works fine with the JIT. However, MCJIT insists on resolving
unknown symbols by searching them outdoors and seems oblivious of the
existence of MyLazyFunctionCreator.
Is this a bug?...

[LLVMdev] Handling of thread_local globals by llc -march=cpp
Hello
> I've been exploring thread local globals in llvm and as part of this investigation I ran llc -march=cpp over a trivial llvm bc file which uses thread local storage for a global. For some reason llc -march=cpp seems to ignore the thread_local and produce code to create a standard global. Is this expected behaviour, a known limitation, or otherwise?
Thanks for the report. Should be

[LLVMdev] Handling of thread_local globals by llc -march=cpp
...IntegerType::get(getGlobalContext(), 32), false, GlobalValue::ExternalLinkage, 0, "global", 0, true);
in order to create a thread local global variable instead of a standard global variable causes the function (which uses the global) produced by the following line of code:
void *FPtr = MyExecutionEngine->getPointerToFunction(MyFunction);
to segfault when I call it in the following sequence of code:
int (*FP)() = (int (*)())FPtr;
int res = FP();
when the function executes correctly in the case of instead having created a standard global variable.
Doh!
As far as I got with this was to note t...

[LLVMdev] Adding code after compilation
Hi,
I want to be able add a function to a module after it is (partly) compiled in JIT. Let's say we have these functions:
Foo()
{
Stuff;
}
Bar()
{
Foo();
MoreStuff;
}
I want to have a module with Foo optimized and have a callable pointer to Foo. Later, I want to generate Bar, optimize it (so Foo is inlined) and than get a callable pointer to Bar.
Is this possible?
If so, is there a way to

[LLVMdev] Get the value of a GlobalVariable
Hi,
I am executing a C program using JIT. When the program exits, the control
comes back to my program which initiates the JIT. Now, I want to read
the value(not the LLVM nomenclature) of a global variable (not the LLVM
nomenclature). I am able to get the global variable, using the following
command:
GlobalVariable *my_global = Mod->getNamedGlobal("MY_GLOBAL");
I want to know the

[LLVMdev] Handling of thread_local globals by llc -march=cpp
I note also that this is not a currently unsupported target case where an error should/could/would be produced on attempting to emit code with thread local references. I say this because clang is able to compile both c source with __thread on a global and bc containing a @variable = thread_local global ... and a function that references the thread local global variable to both assembly and machine

[LLVMdev] Handling of thread_local globals by llc -march=cpp
Hi all,
I've been exploring thread local globals in llvm and as part of this investigation I ran llc -march=cpp over a trivial llvm bc file which uses thread local storage for a global. For some reason llc -march=cpp seems to ignore the thread_local and produce code to create a standard global. Is this expected behaviour, a known limitation, or otherwise?
Thanks in advance.
