[PPC64] Remove support for ELF V1 ABI in LLD The current support for V1 ABI in LLD is incomplete. This patch removes V1 ABI support and changes the default behavior to V2 ABI, issuing an error when using the V1 ABI. It also updates the testcases to V2 and removes any V1 specific tests. Differential Revision: https://reviews.llvm.org/D46316 llvm-svn: 331529

[PPC64] toc-indirect to toc-relative relaxation This is based on D54720 by Sean Fertile. When accessing a global symbol which is not defined in the translation unit, compilers will generate instructions that load the address from the toc entry. If the symbol is defined, non-preemptable, and addressable with a 32-bit signed offset from the toc pointer, the address can be computed directly. e.g. addis 3, 2, .LC0@toc@ha # R_PPC64_TOC16_HA ld 3, .LC0@toc@l(3) # R_PPC64_TOC16_LO_DS, load the address from a .toc entry ld/lwa 3, 0(3) # load the value from the address .section .toc,"aw",@progbits .LC0: .tc var[TC],var can be relaxed to addis 3,2,var@toc@ha # this may be relaxed to a nop, addi 3,3,var@toc@l # then this becomes addi 3,2,var@toc ld/lwa 3, 0(3) # load the value from the address We can delete the test ppc64-got-indirect.s as its purpose is covered by newly added ppc64-toc-relax.s and ppc64-toc-relax-constants.s Reviewed By: ruiu, sfertile Differential Revision: https://reviews.llvm.org/D60958 llvm-svn: 360112
