The following are the most significant peculiarities of MIPS target: - MIPS ABI requires some special tags in the dynamic table. - GOT consists of two parts local and global. The local part contains entries refer locally visible symbols. The global part contains entries refer global symbols. - Entries in the .dynsym section which have corresponded entries in the GOT should be: * Emitted at the end of .dynsym section * Sorted accordingly to theirs GOT counterparts - There are "paired" relocations. One or more R_MIPS_HI16 and R_MIPS_GOT16 relocations should be followed by R_MIPS_LO16 relocation. To calculate result of R_MIPS_HI16 and R_MIPS_GOT16 relocations we need to combine addends from these relocations and paired R_MIPS_LO16 relocation. The patch reviewed by Michael Spencer, Shankar Easwaran, Rui Ueyama. http://llvm-reviews.chandlerc.com/D2156 llvm-svn: 197342
