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

GCCBuiltin just gives it a name for clang to lookup. Generally they match up with builtins that gcc also implements, but that's not a requirement. If you add a builtin with the same name to the builtin file in clang's include/clang/Basic/Builtins*.def then they will find each other. You can also just add a builtin to clang's builtin file and catch it in clang's

I've created an intrinsic from my target, but I can't figure out how I can run it from a C code. Most of the targets have a GCCBuiltin and it looks like it is the way to execute an intrinsic from C code. However in my case there is no actual GCC built in. Any help on this is really appreciated. -- Rail Shafigulin Software Engineer Esencia Technologies -------------- next part
