Hafiz Abid Qadeer 5ad78e6343 [AMDGPU] Handle s_branch to another section. ... Currently, if target of s_branch instruction is in another section, it will fail with the error of undefined label. Although in this case, the label is not undefined but present in another section. This patch tries to handle this issue. So while handling fixup_si_sopp_br fixup in getRelocType, if the target label is undefined we issue an error as before. If it is defined, a new relocation type R_AMDGPU_REL16 is returned. This issue has been reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100181 and https://bugs.llvm.org/show_bug.cgi?id=45887. Before https://reviews.llvm.org/D79943, we used to get an crash for this scenario. The crash is fixed now but the we still get an undefined label error. Jumps to other section can arise with hold/cold splitting. A patch to handle the relocation in lld will follow shortly.
