Hello,

I think the ppc64 ELF ABI is officially wierd.

For "main" the minimal symbol table contains two symbols vis:

	main: points at descriptor in .opd sectoin
	.main: points at main's code entry point

Consequently, given only a minimal symbol table, GDB, when given:

	(gdb) break main

will try to insert the breakpoint in the descriptor, and not the 
function.  Trying to enter:

	(gdb) break .main

gets you no where (syntax error :-/)

Adding to the fun, GCC's debug info contains the symbol "main" which 
points at the code address (and not the descriptor) and consequently 
debugging with symbols works.  Yes, this means that "main" has two 
different values, arrrghghgh!!

Attatched is a hack to breakpoint.c that applies "convert from func ptr 
addr" to any address.  This causing the breakpoint code to convert 
"main" into ".main" and hence work.

I don't know if its a right fix, good fix, or of any other alternative 
fix.  However it does work ...

help!
