We want to express that the DIE of S::T<int> must be a child of the DIE of S, like in assembly this output:
.uleb128 0x2 # (DIE (0x9e) DW_TAG_structure_type)
.ascii "S\0" # DW_AT_name
.byte 0x1 # DW_AT_byte_size
.byte 0x1 # DW_AT_decl_file (../../prtests/test-PR45024.cc)
.byte 0x1 # DW_AT_decl_line
.long 0xbc # DW_AT_sibling
.uleb128 0x3 # (DIE (0xa8) DW_TAG_structure_type)
.ascii "T<int>\0" # DW_AT_name
.byte 0x1 # DW_AT_byte_size
.byte 0x1 # DW_AT_decl_file (../../prtests/test-PR45024.cc)
.byte 0x2 # DW_AT_decl_line
.uleb128 0x4 # (DIE (0xb3) DW_TAG_template_type_param)
.ascii "Z\0" # DW_AT_name
.long 0xbc # DW_AT_type
.byte 0 # end of children of DIE 0xa8
.byte 0 # end of children of DIE 0x9e
Hence the slightly odd regexp:
{ dg-final { scan-assembler "\[^\n\r\]*\\(DIE\[^\n\r\]*DW_TAG_structure_type\\)\[\n\r\]+\[^\n\r\]*\"S\\\\0\"\[ \t\]+\(\[@|#;!\]|//?\)\[ \t\]+DW_AT_name\[\n\r\]+\(.*\)?\\(DIE\[^\n\r\]*DW_TAG_structure_type\\)\[\n\r\]+\[^\n\r\]*\"T<int>\\\\0\"\[ \t\]+\(.*\)?\\(DIE\[^\n\r\]*DW_TAG_template_type_param\\)\[\n\r\]+\[^\n\r\]*\[\n\r\]+\[^\n\r\]*\[\n\r\]+\[^\n\r\]*\(\[@|#;!\]|//?\)\[ \t\]+end of children of DIE\[^\n\r\]*\[\n\r\]+\[^\n\r\]*end of children of DIE\[^\n\r\]*" } }
