The patch introduces two new relocations expressions R_MIPS_GOT_GP and R_MIPS_GOT_GP_PC. The first one represents a current value of `_gp` pointer and used to calculate relocations against the `__gnu_local_gp` symbol. The second one represents the offset between the beginning of the function and the `_gp` pointer's value. There are two motivations for introducing new expressions: - It's better to keep all non-trivial relocation calculations in the single place - `getRelocTargetVA` function. - Relocations against both `_gp_disp` and `__gnu_local_gp` symbols depend on the `_gp` value. It's a magical value points to the "middle" of GOT. Now all relocations use a common `_gp` value. But in fact, under some conditions each input file might require its own `_gp` value. I'm going to implement it in the future patches. So it's better to make `MipsGotSection` responsible for calculation of the `_gp` value. llvm-svn: 298306 |
