Question about 'isUnsignedDIType' function on DwarfUnit.cpp
Hi All,
I have question about 'isUnsignedDIType' function on
'llvm/lib/CodeGen/AsmPrinter/DwarfUnit.cpp'
When we want to generate object file with dwarf debug format, clang
can generates 'DW_ATE_lo_user' encoding for complex integer type as
follow:
"clang/lib/CodeGen/CGDebugInfo.cpp"
llvm::DIType *CGDebugInfo::Cre...

[LLVMdev] Signed/unsigned value type resolution
...f view it can be very important to know whether, for
example, 0xFFFFFFFF means 65535 or -1 (assuming 16 bits), particularly
when values are represented by conceptually infinitiary abstract
domains.
There seems to be some support in the head version in the DIType class
(specifically DIType::isUnsignedDIType()) for extracting this
information from debug metadata, though this member function is
missing in 2.9. It is also sometimes possible to infer signedness from
context, since certain instructions imply it, but I'm finding that
doing that still leaves many cases unresolved.
What's the...
