[LLVMdev] one question about up reference
hi,
I have one question about up reference, why use \nested_level_count in type description.
and have to handle it in HandleUpRefs() (AsmParser/llvmAsmParser.y) ,
why not just insert type name and return in calcTypeName() (AsmWriter.cpp) ;
As you mention in "How to build recursively type" ,
%mylist = type { %mylist*, int } is accepted .
Is it neccessary to use \nested_level_count ?
I'm very thankful if you can give me some C code example to show it .

[LLVMdev] Proposed: first class packed structures
Currently, Structure layout is left to targets, which implement them
according to the ABI of that platform. While this is fine for most
structures, it makes packed structures very ugly. All fields in a
packed type must be converted to byte arrays with casts to access
fields, which bloats accesses and obsfucates the types. First class
support for packed types would clean up the generated code

[LLVMdev] Structure Types and ABI sizes
Hi all,
We're hitting some walls here when generating the correct structure
layout for specific C++ ABI requirements, and I was wondering how much
StructLayout could help.
For instance, the ABI has some complicated rules on the size of
derived classes
(http://www.codesourcery.com/public/cxx-abi/abi.html#class-types) and
LLVM struct type cannot reflect that in full.
Example:
// CHECK:
