你好！试试这个DEMO工程也出现hole warning。发到您邮箱了。

出现hole警告后编译结果正常。

• Subject: Binutils version for GCC 4.8

Hello,

do I need a specific Binutils version (I use version 2.22) for GCC 4.8 (trunk)? I have problems with the debug information:

powerpc-rtems4.11-objdump --dwarf some.exe  > /dev/null
powerpc-rtems4.11-objdump: Warning: There is a hole [0xf2dc7 - 0xf2def] in .debug_loc section.

powerpc-rtems4.11-objdump: Warning: There is an overlap [0x32be0 - 0x32bc8] in .debug_ranges section.

GDB 7.4.1 says that:

(gdb) s
Single stepping until exit from function _Workspace_Handler_initialization,
which has no line number information.
0x00000410 in bsp_work_area_initialize ()

Other debugger refuse to load the ELF file.  Has someone a hint how I can check that the debug information is ok?

看到这编email，是不是问题出在编译器上。

Dear TECH_JW 你好！

MRS Hole Warning! 排查情况怎么样了？贵司提供的工程排查也一样有hole warning

您好，这个警告是在生成反汇编文件时勾选了调试信息，然后生成的警告信息，正常不用勾选这个。

参考EVT这里的勾选如下图
