or1k: Add relocations for high-signed and low-stores
This patch adds the following target relocations: - BFD_RELOC_HI16_S High 16-bit relocation, for used with signed asm: ha() lower. - BFD_RELOC_HI16_S_GOTOFF High 16-bit GOT offset relocation for local asm: gotoffha() symbols, for use with signed lower. - BFD_RELOC_OR1K_TLS_IE_AHI16 High 16-bit TLS relocation with initial asm: gottpoffha() executable calculation, for use with signed lower. - BFD_RELOC_OR1K_TLS_LE_AHI16 High 16-bit TLS relocation for local executable asm: tpoffha() variables, for use with signed lower. - BFD_RELOC_OR1K_SLO16 Split lower 16-bit relocation, used with asm: lo() OpenRISC store instructions. - BFD_RELOC_OR1K_GOTOFF_SLO16 Split lower 16-bit GOT offset relocation for asm: gotofflo() local symbols, used with OpenRISC store instructions. - BFD_RELOC_OR1K_TLS_LE_SLO16 Split lower 16-bit relocation for TLS local asm: tpofflo() executable variables, used with OpenRISC store instructions. bfd/ChangeLog: yyyy-mm-dd Richard Henderson <rth@twiddle.net> Stafford Horne <shorne@gmail.com> * bfd-in2.h: Regenerated. * elf32-or1k.c (N_ONES): New macro.
