Hi, I'm trying to implement the ZC inline assembly constraint for Mips. This constraint is a memory constraint that expands to an address with an offset (the range of the offset varies according to the subtarget), so the inline assembly in: int data[10]; void ZC(void) { asm volatile ("foo %0 %1" : : "ZC"(data[1]), "ZC"(data[2])); } Should expand to

This patch adds EmitTypeAuxAttribute() function to CGDebugInfo, which allows other parts of clang issue auxiliary information through an enumeration type in Dwarf information. For example, by calling DI->EmitTypeAuxAttribute(type, "ID", 1234); We can get following information in dwarf: <1><3f>: Abbrev Number: 3 (DW_TAG_structure_type) <40> DW_AT_name
