Bug ID: 65934
Summary: objdump can't print correct DW_AT_encoding name
Product: gcc
Version: 4.8.3
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: jamesgua at ca dot ibm.com
Target Milestone: ---
In DWARF 4 spec DW_ATE_UTF is value 0x10 or 16, but objdump can't map that
value to UTF, instead, print "unknown type":
e.g.
char16_t utf16 = u'a';
...
<3><148>: Abbrev Number: 7 (DW_TAG_variable)
<149> DW_AT_name : (indirect string, offset: 0x139): utf16
<14d> DW_AT_decl_file : 1
<14e> DW_AT_decl_line : 9
<14f> DW_AT_type : <0x178>
<153> DW_AT_location : 3 byte block: 91 de 7e (DW_OP_fbreg: -162)
...
<1><178>: Abbrev Number: 2 (DW_TAG_base_type)
<179> DW_AT_byte_size : 2
<17a> DW_AT_encoding : 16 (unknown type)
<17b> DW_AT_name : (indirect string, offset: 0x13f): char16_t
It should be displayed UTF like similar to other values
...
<1c8> DW_AT_encoding : 7 (unsigned)
