From aa71428378c1cb491ca60041d8ba7aa110bc963d Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 25 Oct 2012 12:27:42 +0000 Subject: Initial TOC support for PowerPC64 object creation This patch adds initial PPC64 TOC MC object creation using the small mcmodel (a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC, R_PPC64_TOC16, and R_PPC64_TOC16DS). The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter' is meant to avoid the creation of an unreferenced ".TOC." symbol (used in the .odp creation) as well to set the R_PPC64_TOC relocation target as the temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should not point to any symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166677 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/MC/MCELFObjectWriter.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include') diff --git a/include/llvm/MC/MCELFObjectWriter.h b/include/llvm/MC/MCELFObjectWriter.h index abbe188..4ffea8d 100644 --- a/include/llvm/MC/MCELFObjectWriter.h +++ b/include/llvm/MC/MCELFObjectWriter.h @@ -85,6 +85,9 @@ public: const MCFragment &F, const MCFixup &Fixup, bool IsPCRel) const; + virtual const MCSymbol *undefinedExplicitRelSym(const MCValue &Target, + const MCFixup &Fixup, + bool IsPCRel) const; virtual void adjustFixupOffset(const MCFixup &Fixup, uint64_t &RelocOffset); -- cgit v1.1
