From cd72557d0f285d4af9080ed36d093e8e524001a3 Mon Sep 17 00:00:00 2001 From: "xumingjie.enna1" Date: Thu, 26 Jun 2025 09:35:14 +0800 Subject: [PATCH] [LLD][ELF] Skip non-SHF_ALLOC sections when checking max VA and max VA difference in relaxOnce() For non-SHF_ALLOC sections, sh_addr is set to 0. Skip sections without SHF_ALLOC flag, so `minVA` will not be set to 0 with non-SHF_ALLOC sections, and the size of non-SHF_ALLOC sections will not contribute to `maxVA`. --- lld/ELF/Arch/X86_64.cpp | 2 ++ 1 file changed, 2 insertions(+) diff --git a/lld/ELF/Arch/X86_64.cpp b/lld/ELF/Arch/X86_64.cpp index 163505102d0ec..488f4803b2cb4 100644 --- a/lld/ELF/Arch/X86_64.cpp +++ b/lld/ELF/Arch/X86_64.cpp @@ -320,6 +320,8 @@ bool X86_64::deleteFallThruJmpInsn(InputSection &is, InputFile *file, bool X86_64::relaxOnce(int pass) const { uint64_t minVA = UINT64_MAX, maxVA = 0; for (OutputSection *osec : ctx.outputSections) { + if (!(osec->flags & SHF_ALLOC)) + continue; minVA = std::min(minVA, osec->addr); maxVA = std::max(maxVA, osec->addr + osec->size); }
