...constant offset from the .got section. Also it might be defined by a linker script. And in rare but possible case it comes from .reginfo / .MIPS.options sections. Got example, GNU bfd linker has the following code to adjust _gp-relative relocation addends: rel->r_addend += _bfd_get_gp_value (input_bfd); rel->r_addend -= _bfd_get_gp_value (output_bfd); But I think we can escape to implement the same adjustments in LLD if we do not support non-zero gp-value in the .reginfo / .MIPS.options sections in input object files. We can get such files if somebody produce a relocatable object file by bf...

You are right. LLD does not have this problem. Initially I bumped into the MIPS specific bug related to GP relative relocations calculation. I tried to make reproduction script as general as possible and mistakenly make it too general. So now with your help I realized that the problem solely affects MIPS.

Dear llvmdev, I am new to LLVM , but have a task on writing a LLVM backend to generate some architecture specific assembly file. Here is my cygwin build setting: GCC 3.4.4 , BIN UTILITY 2.15 ,and all other packages of the right version listed on the LLVM Getting Started doc. I have successfully built Release 1.6 LLVM. All the tools has been installed there /usr/local/bin . But I
