debug info getting removed with --gc-sections flag

[Ian Thompson]

Hi,

I'm using the mips gcc cross-compiler in little-endian mode, and 
running into a problem with the --gc-sections linker flag.  I can 
compile and run code just fine using the flag, but when I try and load 
the program into a debugger, it can't read the debugging information 
correctly.  I'm using the stab debug format (-gstabs for gcc, --gstabs 
for asm).  I'm guessing that the linker flag is somehow removing a 
necessary debug section, but when I do a readelf on the executable,
the mdebug section is present with or without the --gc-sections flag.

Has anyone run into this problem before?

thanks,
ian
