[llvm-dev] ORC Assertion failure

Hi

On Windows 10 when using a debug build of LLVM 10, I get this assertion failure:

Assertion failed: (KV.second.getFlags() & ~WeakFlags) == (I->second &
~WeakFlags) && "Resolving symbol with incorrect flags", file
C:\work\github\llvm-10.0.0.src\lib\ExecutionEngine\Orc\Core.cpp, line
450

The same failure occurred in LLVM 9 too:

Assertion failed: I->second == KV.second.getFlags() &&
"Resolving
symbol with incorrect flags", file
C:\work\github\llvm-9.0.0.src\lib\ExecutionEngine\Orc\Core.cpp, line
384

I am unsure what this assertion means and how I can debug this.

The assertion seems to occur just after JIT compiling a function, when
my code is trying to get the compiled function's address using
something like this:

return ES->lookup({MainJD}, (*Mangle)(Name.str()));

Here is the call stack:

[llvm-dev] ORC Assertion failure

Hi,

Some more info:

The values that are causing the failure are:

I.second {TargetFlags=0 '\0' Flags=None (0 '\0') }
KV.second {Address=1438723211264 Flags={TargetFlags=0 '\0'
Flags=Callable (32 ' ') } }

In line:

    assert((KV.second.getFlags() & ~WeakFlags) == (I->second &
~WeakFlags) &&
           "Resolving symbol with incorrect flags");

[llvm-dev] ORC Assertion failure

Interestingly this assertion failure occurs with ORC v2 but not ORC v1.

[llvm-dev] ORC Assertion failure

Hi Dibyendu,

Are you using LLJIT?

If you're using a custom JIT class you will need to call
'ObjLinkingLayer->setOverrideObjectFlagsWithResponsibilityFlags(true);'
when running on Windows, as RuntimeDyldCOFF does not correctly report
symbol flags yet.

-- Lang.
