...tly, you're supposed to write. for (llvm::object::section_iterator iter = Obj.begin_sections (); iter != Obj.end_sections(); iter.increment(ec)) Srsly? [ And - how do I go from a section_iterator to a coff_section ? ] While I'm puzzling over that, I look some more, and I see: error_code getSection(int32_t index, const coff_section *&Res) const; Cool. (A bit weird; why a signed index?, but whatever) So I write: const llvm::object::coff_section *sect; for (std::size_t i = 0; i < NumSections; ++i) Obj.getSection(i, sect); And my program dies with a segmentation fault. Turns o...

...e lowering stage and also at the AsmPrinter stage, I need to know if a GlobalAddress is a code or a data address. So I tried at the lowering stage to use: GlobalAddressSDNode *GSDN = cast<GlobalAddressSDNode>(Op); const GlobalValue *GV = GSDN->getGlobal(); GV->hasSection() and GV->getSection() But the section is not set at this stage (hasSection = false) And at the AsmPrinter stage: const GlobalValue *GV = MO.getGlobal(); SectionKind sectionKind = Mang->getSymbol(GV)->getSection().getKind(); But again the section does not seem to be set (sectionKind.isInSection() = false) Do...

Michael, I have rework the patch according to your suggestion. And I have read binutil/objdump source code and found that it has a logic that if there's no symtab, it will use dynsym, which is missing in llvm-objdump.

...Sanjiv, The PIC16TargetAsmInfo::getBSSSectionForGlobal apparently does magic that reinterprets the "section" field of a global in a strange way: // If GV has a sectin name or section address create that section now. if (GV->hasSection()) { std::string SectName = GV->getSection(); // If address for a variable is specified, get the address and create // section. std::string AddrStr = "Address="; if (SectName.compare(0, AddrStr.length(), AddrStr) == 0) { std::string SectAddr = SectName.substr(AddrStr.length()); S = CreateSect...

Hello, Pekka > 12) getSectionForFunction(*f) to f->getSection() This is not a correct substitution. Function::getSection() returns section set on function explicitely, getSectionForFunction() calculated desired section name, where function should be emitted into (for example, unique function name for linkonce stuff). get...

...t it could be any section. I can get a MCSectionELF class object from MCSymbol that I get from MCSymbolRefExpr: int Kind = Value->getKind(); if (Kind == MCExpr::SymbolRef) { const MCSymbol &Sym = SRE->getSymbol(); const MCSectionELF = dyn_cast_or_null<MCSectionELF>(Sym.getSection()); } But can't see how to get the virtual address of the section. This is odd since I would have expected methods for accessing every part of the ELF section header entry. How does one get the virtual address (sh_addr in ELF) starting from a MCSymbolRefExpr? Thanks, Jack -------------...

In the 2.3 release, we included a list of the major LLVM API changes. If you are working on upgrading your code from 2.3 to 2.4, I'd appreciate it if you could compile a list of the major stumbling blocks you have, so that others can benefit from your experience. Please send any info to the list, thanks! -Chris
