Hi, I need an advice on implementation of a very specific kind of relocations used by MIPS N64 ABI. As usual the main problem is how to pass target specific data over Native/YAML conversion barrier. In this ABI relocation record r_info field in fact consists of five subfields: * r_sym - symbol index * r_ssym - special symbol * r_type3 - third relocation type * r_type2 - second relocation type * r_type - first relocation type Up to three these relocations applied one by one. The first relocation uses an addendum from the relocation record. Each subsequent relocation takes as...

When LLD builds a shared library for x86_64 it puts _GLOBAL_OFFSET_TABLE_ to the both .symtab and .dynsym and defines it as a GLOBAL symbol. If later this shared library participates in executable file linking and GNU BFD linked is used for that, this linker shows an error: /usr/bin/ld: a.out: hidden symbol `_GLOBAL_OFFSET_TABLE_' in /usr/lib/x86_64-linux-gnu/crt1.o is referenced by DSO Gold
