[Crash-utility] fix gdb_get_datatype cannot handle integer type

Hi Dave, Current when pass integer type to gdb_get_datatype in crash, it would return req->typecode=0 and req->length=0. As it only allow TYPE_CODE_ENUM to be passed. here is a patch for fixing it. Do you think it could be merged? +--- gdb-7.3.1/gdb/symtab.c ++++ gdb-7.3.1/gdb/symtab.c +@@ -5064,14 +5064,13 @@ gdb_get_datatype(struct gnu_request *req) + if (gdb_CRASHDEBUG(2)) + console("expr->elts[0].opcode: OP_VAR_VALUE\n"); + type = expr->elts[2].symbol->type; +- if (TYPE_CODE(type) == TYPE_CODE_ENUM) { +- req->typecode = TYPE_CODE(type); +- req->value = SYMBOL_VALUE(expr->elts[2].symbol); +- req->tagname = TYPE_TAG_NAME(type); +- if (!req->tagname) { +- val = evaluate_type(expr); +- eval_enum(value_type(val), req); +- } ++ req->typecode = TYPE_CODE(type); ++ req->length = TYPE_LENGTH(type); ++ req->value = SYMBOL_VALUE(expr->elts[2].symbol); ++ req->tagname = TYPE_TAG_NAME(type); ++ if (!req->tagname) { ++ val = evaluate_type(expr); ++ eval_enum(value_type(val), req); + } + break; + Thanks, Lei
