Merge commit f457863ae345 from llvm git (by Fangrui Song): [ELF] Support REL-format R_AARCH64_NONE relocation -fprofile-use=/-fprofile-sample-use= compiles may produce REL-format .rel.llvm.call-graph-profile even if the prevailing format is RELA on AArch64. Add R_AARCH64_NONE to getImplicitAddend to fix this linker error: ``` ld.lld: error: internal linker error: cannot read addend for relocation R_AARCH64_NONE PLEASE submit a bug report to https://crbug.com and run tools/clang/scripts/process_crashreports.py (only works inside Google) which will upload a report and include the crash backtrace. ``` Merge commit 53fc5d9b9a01 from llvm git (by Fangrui Song): [ELF] Support R_PPC_NONE/R_PPC64_NONE in getImplicitAddend Similar to f457863ae345d2635026501f5383e0e625869639 Merge commit 767e64fc11d7 from llvm git (by Fangrui Song): [ELF] Support some absolute/PC-relative relocation types for REL format ctfconvert seems to use REL-format `.rel.SUNW_dof` for 32-bit architectures. ``` Binary file usr/ports/lang/perl5.32/work/perl-5.32.1/dtrace_mini.o matches [alfredo.junior@dell-a ~/tmp/llvm-bug]$ readelf -r dtrace_mini.o Relocation section (.rel.SUNW_dof): r_offset r_info r_type st_value st_name 00000184 0000281a R_PPC_REL32 00000000 $dtrace1772974259.Perl_dtrace_probe_load ``` Support R_PPC_REL32 to fix `ld.lld: error: drti.c:(.SUNW_dof+0x4E4): internal linker error: cannot read addend for relocation R_PPC_REL32`. While here, add some common relocation types for AArch64, PPC, and PPC64. We perform minimum tests.
