[gdb/testsuite] Fix info-types.exp with gcc/g++ 4.8
The gdb.base/info-types.exp test-case FAILs with gcc/g++ 4.8 because the DWARF record for the 'unsigned int' type is missing in the executables, while it is present for gcc/g++ 7.4.1. For a minimal example using gcc 7.4.1: ... $ echo "enum enum_t { AA, BB, CC }; enum enum_t var;" > enum.c $ gcc enum.c -c -g ... we find that the enum type has DW_AT_encoding 'unsigned': <1><1d>: Abbrev Number: 2 (DW_TAG_enumeration_type) <1e> DW_AT_name : (indirect string, offset: 0x1f): enum_t <22> DW_AT_encoding : 7 (unsigned) <23> DW_AT_byte_size : 4 <24> DW_AT_type : <0x3e> <28> DW_AT_decl_file : 1 <29> DW_AT_decl_line : 1 <2a> DW_AT_sibling : <0x3e> ... and a DW_AT_type reference to the type 'unsigned int': ... <1><3e>: Abbrev Number: 4 (DW_TAG_base_type) <3f> DW_AT_byte_size : 4 <40> DW_AT_encoding : 7 (unsigned) <41> DW_AT_name : (indirect string, offset: 0x26): unsigned int ... With gcc 4.8.5 however, we have no 'unsigned' encoding, and no DW_AT_type: ... <1><1d>: Abbrev Number: 2 (DW_TAG_enumeration_type) <1e> DW_AT_name : (indirect string, offset: 0x1f): enum_t <22> DW_AT_byte_size : 4 <23> DW_AT_decl_file : 1 <24> DW_AT_decl_line : 1 <25> DW_AT_sibling : <0x39> ... as well as no record for 'unsigned int'. Make the test-case pass with gcc/g++ 4.8 by making the presence of the 'unsigned int' type optional.
