In Operand_soffsetx4_decode: soffsetx4_0 = 0x4 + ((((int) offset_0 << 14) >> 14) << 2); and other places. Don't sign extend with shifts! This file also has many occurrences of truncation via shifts, which aren't a problem due to using uint32, but I dislike on principle enough to fix. * xtensa-modules.c (Field_* functions): Don't mask using shifts.

2019-12-07PR25236, common sym versioningAlan Modra2-3/+11
In cases where a relocatable object file has a common symbol, no other file has a definition, and there is a matching common symbol found in a shared library then ld will output a definition using the largest of size and alignment for the commons. This patch fixes a bug in ld that ignored common symbols when assigning versions, resulting in such symbols being given VER_NDX_LOCAL versions. PR 25236 * elflink.c (_bfd_elf_link_assign_sym_version): Assign versions for ELF_COMMON_DEF_P symbols. (elf_link_output_extsym, _bfd_elf_add_default_symbol): Adjust to suit.

This bug was observed on nios2-linux-gnu with some C++ programs linked with -pie or -shared.
