Bug ID: 46431
Summary: [codeview] The 'this' symbol is not marked as compiler
generated.
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: DebugInfo
Assignee: unassignedb...@nondot.org
Reporter: international.phan...@gmail.com
CC: jdevliegh...@apple.com, keith.wal...@arm.com,

For the given test:
//----------------------------------------------------------
class CLASS {
public:
int member(int Param);
};
int CLASS::member(int Param) {
return Param;
}
//----------------------------------------------------------
----------------------------
CodeView generated by Clang:
----------------------------
0 | S_GPROC32_ID `CLASS::member`
type = `0x1008 (member)`, flags = none
0 | S_LOCAL `this`
type=0x1009 (CLASS*), flags = param
0 | S_LOCAL `Param`
type=0x0074 (int), flags = param
0 | S_PROC_ID_END
Both 'this' and 'Param' are marked as 'param' (LocalSymFlags::IsParameter).
The 'this' should have the (LocalSymFlags::IsCompilerGenerated) as well.
-------------------------
DWARF generated by Clang:
-------------------------
DW_TAG_class_type
DW_AT_name ("CLASS")
DW_TAG_subprogram
DW_AT_name ("member")
DW_AT_type (0x00000064 "int")
DW_AT_accessibility (DW_ACCESS_public)
DW_TAG_formal_parameter
DW_AT_type (0x0000006b "CLASS*")
DW_AT_artificial (true)
DW_TAG_formal_parameter
DW_AT_type (0x00000064 "int")
Only the 'this' parameter is marked as 'DW_AT_artificial', indicating that is
compiler generated.
