该问题是因为anolis23上的perf是经过strip的，查找dwarf_unwind符号为空，所以测试DWARF-unwind无法识别对应的函数符号，从而报错。anolis8上的perf工具有dwarf_unwind函数符号，所以它不报错。使用upstream的代码在anolis23上测试，并将perf进行strip，该测试项也会fail，因此该问题暂时置为later. 查看anolis23上的perf工具没有dward_unwind相关函数符号： [root@iZbp11g4dg2q997fe12m38Z perf]#objdump -tT /usr/bin/perf | grep dwarf_unwind [root@iZbp11g4dg2q997fe12m38Z perf]# 在anolis23上通过源码直接make，可以看到刚编译的perf工具有dwarf_unwind相关符号，且该测试是通过的，然后strip perf，没有dwarf_unwind相关符号，该测试失败。 [root@iZbp11g4dg2q997fe12m38Z perf]# ./perf test 70 70: Test dwarf unwind : Ok [root@iZbp11g4dg2q997fe12m38Z perf]# objdump -tT perf | grep dwarf_unwind 0000000000ca8400 g O .data 0000000000000018 suite__dwarf_unwind 000000000047ccb0 g F .text 000000000000006a test_dwarf_unwind__krava_3 000000000047cd20 g F .text 0000000000000032 test_dwarf_unwind__krava_2 000000000047cd60 g F .text 0000000000000032 test_dwarf_unwind__krava_1 000000000047cda0 g F .text 000000000000015a test__dwarf_unwind 000000000047cc20 g F .text 000000000000008b test_dwarf_unwind__compare 0000000000ca8420 g O .data 0000000000000040 tests__dwarf_unwind 000000000047cb00 g F .text 000000000000011e test_dwarf_unwind__thread [root@iZbp11g4dg2q997fe12m38Z perf]# [root@iZbp11g4dg2q997fe12m38Z perf]# strip perf [root@iZbp11g4dg2q997fe12m38Z perf]# objdump -tT perf | grep dwarf_unwind [root@iZbp11g4dg2q997fe12m38Z perf]# [root@iZbp11g4dg2q997fe12m38Z perf]# ./perf test 70 70: Test dwarf unwind : FAILED! 在anolis8环境中检查安装的perf工具，可以看到有dwarf_unwind相关符号，因此该项测试也是OK的。 [root@iZuf6i4iwe2asnhp3fn7mpZ ~]# objdump -tT /usr/bin/perf | grep dwarf_unwind 00000000002ed260 g DF .text 0000000000000036 Base test_dwarf_unwind__krava_1 00000000002ed220 g DF .text 0000000000000036 Base test_dwarf_unwind__krava_2 00000000002ed1a0 g DF .text 0000000000000072 Base test_dwarf_unwind__krava_3 00000000002ed100 g DF .text 0000000000000096 Base test_dwarf_unwind__compare 00000000002ecfc0 g DF .text 0000000000000139 Base test_dwarf_unwind__thread 00000000002ed2a0 g DF .text 000000000000014f Base test__dwarf_unwind [root@iZuf6i4iwe2asnhp3fn7mpZ ~]# perf test 72 72: DWARF unwind : Ok
