...term goal is to make TargetAsmInfo not depend on libvmcore. This means that no methods in it should take GlobalValue*'s for example. There is a suite of GV classification methods that need to be moved somewhere else, probably in TargetLowering or asmprinter. One method in particular (SectionForGlobal) is virtual and only re- implemented for PIC16, which makes it an obvious candidate for changing. I don't really understand all the section handling logic, but I have to untangle it. It doesn't seem like it is properly factored somehow, so I'd like to simplify it while I'm...

...ubstitution. 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). getSectionForFunction() was replaced with universal TargetAsmInfo::SectionForGlobal() hook. See, for example, X86ATTAsmPrinter::emitFunctionHeader() for usage and ELFTargetAsmInfo class for example implementation of this hook. -- WBR, Anton Korobeynikov

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 sp...
