2014-10-04 | Discard zero address range eh_frame FDEs | Alan Modra | 3 | -6/+35 | |
These are useless because they can't match any address. In fact, worse than useless because the .eh_frame_hdr lookup table matching addresses to FDEs does not contain information about the FDE range. The table is sorted by address; Range is inferred by the address delta from one entry to the next. So if a zero address range FDE is followed by a normal non-zero range FDE for the same address, everything is good. However, the qsort could just as easily sort the FDEs in the other order, in which case the normal FDE would effectively be seen to have a zero range. bfd/ PR 17447 * elf-bfd.h (struct eh_cie_fde): Comment re NULL u.fde.cie_inf. * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Mark zero address range FDEs for discarding.

2014-09-24 | BFD: Add support for more than one plugin in lib/bfd-plugins | Markus Trippelsdorf | 2 | -52/+63 | |
ar, nm and ranlib currently lack the ability to handle more than one plugin in lib/bfd-plugins. This patch reshuffles the logic in plugin.c to add this functionality. One can now place both llvm and gcc plugins in this directory and have them loaded automatically. Mixed gcc/llvm archives are also supported (but not very useful until ld.bfd and ld.gold also would load multiple plugins and use them to claim different object files).

Do you need "set solib-search-path" or "set sysroot"? That "warning: Could not load shared library..." is mostly harmless (it is a bug in GDB), in the FAIL case it is not printed just because bfd_check_format() fails there. It seems logical to me this way when the 'size' parameter has been already added. Alan Modra: I was wrongly thinking that the section headers were always last when I wrote that code. (They are now!

2014-09-16 | NDS32: Code refactoring of relaxation. | Kuan-Lin Chen | 6 | -2675/+4263 | |
Refactor each relaxation pattern to raise the maintainability. In origin, all patterns is analysed in nds32_elf_relax_section, so it is hard to debug and maintain. Therefore, we classify all patterns into different functions in this patch. Moreover, we adjust all optimizations into nds32_elf_relax_section to take these optimizations in turn. This can promise all relaxation being done after calling gld${EMULATION_NAME}_after_allocation. | |||||
