[LLVMdev] Text or Data symbol
...For my DSP backend, at the 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....

[LLVMdev] PIC16TargetAsmInfo::getBSSSectionForGlobal
Hi 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 = SectN...

[LLVMdev] [ARM] [PIC] optimizing the loading of hidden global variable
Hi, When I’m compiling a code with –fvisibility=hidden –fPIC for ARM, I find that LLVM generates less optimized code than GCC. For example: test.cpp: void init(void *); int g0[100]; int g1[100]; int g2[100]; void foo() { init(&g0); init(&g1); init(&g2); } Clang will emit 1 GOT entry for each GV and 2 instructions to get the address: ldr
