  "message": "[ELF] Enable parallel relocation scanning for -z nocombreloc and PPC64 (#190309)\n\nThe `bool serial` condition in scanRelocations disabled parallelism for\nthree cases: -z nocombreloc, MIPS, and PPC64. Resolve two cases:\n\n- nocombreloc: .rela.dyn is now always created with combreloc\u003dtrue so\n  non-relative relocations are sorted deterministically. Since\n  #187964 already separates relative relocations unconditionally,\n  the only remaining effect of -z nocombreloc is suppressing\n  DT_RELACOUNT (gated on ctx.arg.zCombreloc in DynamicSection).\n\n- PPC64: After #181496 moved scanning into scanSectionImpl, the\n  sole thread-unsafe access is ctx.ppc64noTocRelax (DenseSet::insert).\n  Protect it with ctx.relocMutex, which is already used for rare\n  operations during parallel scanning.\n\nMIPS retains serial scanning due to `MipsGotSection` mutations.",
