I use a plain LLVM 2.6 to jit code for x86_64. My setup falls into the following problem:
The generated code calls some external function whose address is set via addGlobalMapping(), but is more than 2GB away from the generated call.
However, a call imm instruction using a 32bit offset is generated, which due to wrap around calls the wrong address.
After digging for some time in the LLVM source I could not find code that handle this case.
Is there something wrong in my setup? Should I use pre2.7 for this use case?
Thanks in advance,
