If symbol table was cached while section processing for garbage collection, the elf_tdata (abfd)->symtab_hdr pointer is not NULL, but (Elf_Internal_Sym *) symtab_hdr->contents array contains data for local symbols only. But in the repeated relocation processing there is no check whenever the symbol index is local (ELF32_R_SYM (irelscan->r_info) < symtab_hdr->sh_info) or global. This leads to the buffer overflow (global symbol index is out of bounds) and following invalid relocation processing, especially in extra relocation data modifications (f.e. irelscan->r_addend could be decreased by arbitrary values). *elf*-microblaze-no-keep-memory.patch short description: There is incorrect newly allocated buffers handling if internal memory caching is disabled (without --no-keep-memory ld switch). This leads to possible double free(...) calls for such data and results in unexpected ld termination with abort(). I've fixed this issue by implementing similar to the elf32-avr.c data buffer handling. *elf*-imm-check-for-relaxation.patch short description: I've reverted Xilinx path to the original GNU binutils bfd code for microblaze, because this patch incorrectly leaves some "imm -1" instructions in resulting binary file after relaxation and increases executable size. If you look at the IMM instruction argument processing in binutils/gas/config/tc-microblaze.c you will see, that gas checks are similar to the original bfd microblaze_elf_relax_section(...)
