These changes are on top of: https://lore.kernel.org/lkml/20241017001354.56973-1-irogers@google.com/ Prior to these patches PERF_HAVE_DWARF_REGS indicated the presence of dwarf-regs.c in the arch directory. dwarf-regs.c provided upto 4 functions: 1) regs_query_register_offset would translate a register name into a pt_regs offset and was used by BPF prologues. BPF prologues existed for BPF events and support for these was removed many releases ago. This code was dead and could be removed. 2) get_arch_regstr duplicated get_dwarf_regstr and so it could be removed. The case for csky was a little more complicated as the ABI controlled the string. The callers of get_dwarf_regstr were updated to also pass the ELF flags so that on csky the ABI appropriate table could be used. As the argument is only used on csky this a no-op for everything else. 3) get_arch_regnum translated a register name back to a dwarf number and only existed on x86 where "al", "ax", "eax" and "rax" could all mean register 0. This code was moved to util with similar machine/flags logic to get_arch_regstr and for consistency with it. 4) get_powerpc_regs a PowerPC specific function used by annotate that should really be in util. 2 and 3 required the wiring through of the ELF machine and flags in callers to get_dwarf_regstr and get_dwarf_regnum. When these values weren't dependent on an ELF file a new EM_HOST and EF_HOST were added to give the host ELF machine and flags. These 2 #defines got rid of the existing separate arch files and #ifdefs. v3: These files were separated from the rest of the v2 libdw clean up in: https://lore.kernel.org/lkml/CAP-5=fVZH3L-6y_sxLwSmT8WyMXDMFnuqUksNULdQYJCPNBFYw@mail.gmail.com/ Ian Rogers (20): perf bpf-prologue: Remove unused file perf dwarf-regs: Remove PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET perf dwarf-regs: Add EM_HOST and EF_HOST defines perf disasm: Add e_machine/e_flags to struct arch perf dwarf-regs: Pass accurate disassembly machine to get_dwarf_regnum perf dwarf-regs: Pass ELF flags to get_dwarf_regstr perf dwarf-regs: Move x86 dwarf-regs out of arch perf arm64: Remove dwarf-regs.c perf arm: Remove dwarf-regs.c perf dwarf-regs: Move csky dwarf-regs out of arch perf loongarch: Remove dwarf-regs.c perf mips: Remove dwarf-regs.c perf dwarf-regs: Move powerpc dwarf-regs out of arch perf riscv: Remove dwarf-regs.c and add dwarf-regs-table.h perf s390: Remove dwarf-regs.c perf sh: Remove dwarf-regs.c perf sparc: Remove dwarf-regs.c perf xtensa: Remove dwarf-regs.c perf dwarf-regs: Remove get_arch_regstr code perf build: Remove PERF_HAVE_DWARF_REGS tools/perf/Makefile.config | 17 +- tools/perf/arch/arc/annotate/instructions.c | 2 + tools/perf/arch/arm/Makefile | 3 -
