Simon Atanasyan	3a5b6e2750	[ELF][MIPS] Do not create dynamic relocations against _gp_disp symbol ... MIPS _gp_disp designates offset between start of function and gp pointer into GOT therefore any relocations against it do not require dynamic relocation. llvm-svn: 257492	2016-01-12 17:31:45 +00:00
Simon Atanasyan	49f98c742c	[ELF][MIPS] Do not use 'sed' to modify binary files ... On Windows different versions of 'sed' work in different text/binary mode by default. If default mode is text, sed produces corrupted binary files. Unfortunately there is no standard command line option to select the mode. Some 'sed' support '-b' to switch to binary mode, while other ones support '--text' option and does not have '-b' option at all. llvm-svn: 257471	2016-01-12 12:38:43 +00:00
Simon Atanasyan	188558e5eb	[ELF][MIPS] Prevent substitution of _gp_disp symbol ... On MIPS O32 ABI, _gp_disp is a magic symbol designates offset between start of function and gp pointer into GOT. To make seal with such symbol we add new method addIgnoredStrong(). It adds ignored symbol with global binding to prevent the symbol substitution. The addIgnored call is not enough here because this call adds a weak symbol which might be substituted by symbol from shared library.
