+ (bug-11819). I think the best solution is to replace
+ absolute reloc with pc relative reloc in the eh_frame.
+ To do that, we need to support the following issues:
+
+ === For GCC ===
+ * gcc/config/nds32/nds32.h: Define
+ ASM_PREFERRED_EH_DATA_FORMAT to encode DW_EH_PE_pcrel
+ and DW_EH_PE_sdata4 into DWARF exception header when
+ option have '-fpic'.
+
+ === For binutils ===
+ * bfd/: Define new reloc R_NDS32_32_PCREL_RELA.
+ * gas/config/tc-nds32.h: Define DIFF_EXPR_OK. This
+ may break our nds DIFF mechanism, therefore, we
+ must disable all linker relaxations to ensure
+ correctness.
+ * gas/config/tc-nds32.c (nds32_apply_fix): Replace
+ R_NDS32_32_RELA with R_NDS32_32_PCREL_RELA, and
+ do the necessary modification.
+
+ Unfortunately, it still have some problems for nds32
+ to support pc relative reloc in the eh_frame. So I use
+ another solution to fix this issue.
+
+ However, I find that ld always emit TEXTREL marker for
+ R_NDS32_NONE relocs in rel.dyn. These none relocs are
+ correspond to R_NDS32_32_RELA for .eh_frame section.
+ It means that we always reserve redundant entries of rel.dyn
+ for these relocs which actually do nothing in dynamic linker.
+
+ Therefore, we regard these relocs as pc relative relocs
+ here and increase the pc_count. */
