IR code of the bug
I tried to run this code via MCJit:
; ModuleID = 'ohm'
@Vv3ohm1xi = thread_local global i32 3
define i32 @main() #0 {
entry:
%0 = load i32* @Vv3ohm1xi
ret i32 %0
}
LLVMRunFunction and LLVMGetFunctionAddress seem to hang indefinitely for the
function `main`, while LLVMFindFunction returns a handle.
The same code with
@Vv3ohm1xi = global i32 3
instead works as expected.
The default interpreter can run the code but does not initialize the global to
the set value (3 in this case). I can open a new issue for this problem if
wanted.
Steps to reproduce:
Save code to `bug.ir`
Run: `lli bug.ir` (I assume this uses the mc-jit)</pre>
