AIX support

AIX support

[Ivan Popivanov]

Hi,

Does GDB support AIX? Is it possible to debug programs compiled with AIX 
native xlC compiler?

Thanks in advance!
Ivan

GDB does support AIX. I don't know however how well GDB supports
debugging of programs built with xlC.

from my experiences, GDB works well with xl c compiler. but not so well on
xl c++ compiler, especially on virtual class and function.

Sorry that I forget to mention that my experience is on linux.  But I 
think the result might be the same.

Aren't the executable file formats different on AIX and Linux? Does GDB 
support both?

Cheers,

Yes, the executable formats are different. One is COFF based, and the
other is ELF. GDB supports both. (I assume by linux you mean ppc-linux)

ok. I didn't know that the executable file formats on AIX is COFF.  In 
fact I don't have any experiecne coding on AIX.  But I do have some 
experience with xlC compiler on linux.  That is ppc64 arch however.  
GDB will drop into segmentation fault if there are any virtual classes or 
functions in the debugged code. The reason is that xl c++ compiler will
generate a virtual function table for each virtual classes, and so it 
doesn't depends on DW_AT_containing_type like g++ does.     

I don't know what kind of debuginfo XLC will generate on AIX.  If it is 
other than DWARF, or your code don't use any virutal feature of c++, I 
think GDB will work well with xlc compiler on AIX.

Short answer, Yes, GDB works on AIX and with XLC/C++. I have done some
work in this area, you can find test results that I posted to GBDtesters
mailing list. My experience is with gdb mainline with XLC 7.0 on AIX 5.3L.

Thanks
