[llvm-dev] raise exception failed on AARCH

[李阳(如颠) via llvm-dev]

Hi, All,

 

I suppose there must be a BUG!!!!!

 

I am using landingpad on LLVM 6.0.1. I found the exception can be catched successfully on X86, but failed on AARCH.

 

When I debug the libgcc, I found the pc_begin passed from llvm::RTDyldMemoryManager::registerEHFrames is wrong.

 

When the LLVM findSymbol get a address is 0xfffd0db45000, the pc_begin would be 0xffff0db45000. The high 16-bits are different.

 

I upgraded my LLVM from 6.0.1 to 8.0.1. But still failed on AARCH. I really don't know how to solve it? 

 

Thanks~
