or1k: Add the l.adrp insn and supporting relocations
This patch adds the new instruction and relocation as per proposal: https://openrisc.io/proposals/ladrp This is to be added to the spec in an upcoming revision. The new instruction l.adrp loads the page offset of the current instruction offset by a 21-bit immediate shifted left 13-bits. This is meant to be used with a 13-bit lower bit page offset. This allows us to free up the got register r16. l.adrp r3, foo l.ori r4, r3, po(foo) l.lbz r5, po(foo)(r3) l.sb po(foo)(r3), r6 The relocations we add are: - BFD_RELOC_OR1K_PLTA26 For PLT jump relocation with PLT entry asm: plta() implemented using l.ardp, meaning no need for r16 (the GOT reg) - BFD_RELOC_OR1K_GOT_PG21 Upper 21-bit Page offset got address asm: got() - BFD_RELOC_OR1K_TLS_GD_PG21 Upper 21-bit Page offset with TLS General asm: tlsgd() Dynamic calculation - BFD_RELOC_OR1K_TLS_LDM_PG21 Upper 21-bit Page offset with TLS local asm: tlsldm() dynamic calculation - BFD_RELOC_OR1K_TLS_IE_PG21 Upper 21-bit Page offset with TLS Initial asm: gottp() Executable calculation - BFD_RELOC_OR1K_PCREL_PG21 Default relocation for disp21 (l.adrp instructions) - BFD_RELOC_OR1K_LO13 low 13-bit page offset relocation asm: po() i.e. mem loads, addi etc - BFD_RELOC_OR1K_SLO13 low 13-bit page offset relocation asm: po() i.e. mem stores, with split immediate - BFD_RELOC_OR1K_GOT_LO13, low 13-bit page offset with GOT calcs asm: gotpo() - BFD_RELOC_OR1K_TLS_GD_LO13 Lower 13-bit offset with TLS GD calcs asm: tlsgdpo() - BFD_RELOC_OR1K_TLS_LDM_LO13 Lower 13-bit offset with TLS LD calcs asm: tlsldmpo() - BFD_RELOC_OR1K_TLS_IE_LO13 Lower 13-bit offset with TLS IE calcs asm: gottppo() bfd/ChangeLog: yyyy-mm-dd Richard Henderson <rth@twiddle.net> * bfd-in2.h: Regenerated. * elf32-or1k.c: (or1k_elf_howto_table): Fix formatting for R_OR1K_PLT26, Add R_OR1K_PCREL_PG21, R_OR1K_GOT_PG21, R_OR1K_TLS_GD_PG21, R_OR1K_TLS_LDM_PG21, R_OR1K_TLS_IE_PG21, R_OR1K_LO13, R_OR1K_GOT_LO13, R_OR1K_TLS_GD_LO13, R_OR1K_TLS_LDM_LO13, R_OR1K_TLS_IE_LO13, R_OR1K_SLO13, R_OR1K_PLTA26.
