You can call:
SBType
SBValue::GetType();
SBType will describe the type itself. We recently added an enumeration call:
lldb::BasicType
SBType::GetBasicType();
This will return an enumeration that describes your type if is is a basic type
(see the lldb::BasicType enumeration definition for details).
Cool. So I tried that and I get back a eBasicTypeBool for both types in
the attached IR file. I emit it with DIBuilder and pass an DW_ATE_signed
32bits:
!9 = metadata !{i32 786468, null, metadata !"Integer", null, i32 0, i64
32, i64 32, i64 0, i32 0, i32 5} ; [ DW_TAG_base_type ] [Integer] [line
0, size 32, align 32, offset 0, enc DW_ATE_signed]
Is there something special I have to do here? (Integer is the internal
name for this type in my language)
