[LLVMdev] Trying to run qt app compiled to bit code Assertion failed: (Ty->isSized() && "Cannot getTypeInfo() on a type that is unsized!")

[Shailesh Kumar]

Thanks Daniel.
Sure. Attaching the qt app. 

My environment.
1. os x, 
2. qt 5 installed.
3. modify lli to load qt5core,qt5widgets,qt5gui library. I couldnt figure out a way to load these libs as an option to lli.
4. run qmake in the project directory, where you unzip the attachment. Make sure you have Qt 5 binaries in the path. 
5. make
6. llvm-link all .bc files. 


Thanks and Regards,
Shailesh.

Looks like a bug in the DebugIR pass. I imagine that without the -debug–ir flag, you will be able to get a little further.

Nonetheless, can you send me the "bitcodetestqtapp" that you're running, or steps to reproduce? I'd love to take a look.

Thanks,
Dan

Hi,

I am trying to run a simple qt 5 application compiled to bitcode on OS X. I am getting the following error. I have modified lli to load qt libraries. When I use with option mcjit, I get the following error

lli -use-mcjit -debug-ir bitcodetestqtapp

Assertion failed: (Ty->isSized() && "Cannot getTypeInfo() on a type that is unsized!"), function getTypeSizeInBits, file /Users/shailesh/repos/llvm/include/llvm/IR/DataLayout.h, line 449.

Stack dump:
0.Program arguments: lli -use-mcjit -debug-ir bitcodetestqtapp
Illegal instruction: 4


If I dont use mcjit, the window shows up and crashes with the following error. I guess qt uses inline asm somewhere.

lli  bitcodetestqtapp
loading dynamic library error
on timeout 30
LLVM ERROR: JIT does not support inline asm!


Appreciate any help/pointers regarding this.

Thanks,
Shailesh.
