...To rather than using the normal lowering for calls, leading to bad interactions with illegal types. One failure relating to inline asm, and one failure involving ISD::FPOWI where I'm not entirely sure what's supposed to happen. IA64: 56. One big issue is the following assertion: lib/Target/ELFTargetAsmInfo.cpp:175: const llvm::Section* llvm::ELFTargetAsmInfo::MergeableStringSection(const llvm::GlobalVariable*) const: Assertion `getCStringSection() && "Should have string section prefix"' failed. Another major issue is that IA64 has an f64 register type, but not an f32 register t...

...nction() 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
