	gdb            : ChangeLog xcoffread.c 

Log message:
	pspace != NULL failed assertion on ppc-aix
	
	This patch fixes the following problem:
	
	% gdb foo
	(gdb) b main
	/[...]/progspace.c:216: internal-error: set_current_program_space: Assertion `pspace != NULL' failed.
	A problem internal to GDB has been detected,
	further debugging may prove unreliable.
	Quit this debugging session? (y or n)
	
	The problem happens when we try to get the program space from
	a minimal symbol.  For that, we go through the minimal symbol's
	obj_section->objfile->pspace.  But the minimal symbol's obj_section
	is not set, and thus we somehow get a NULL program space. And
	the reason why the obj_section is not set is because the XCOFF
	reader did not pass the bfd_section when calling minsyms.c's
	prim_record_minimal_symbol_and_info.
	
	gdb/ChangeLog:
	
	* xcoffread.c (xcoff_secnum_to_sections): New function.
	(secnum_to_section, secnum_to_bfd_section): Reimplement
	using xcoff_secnum_to_sections.  Rename "secnum" parameter
	into "n_scnum".
	(RECORD_MINIMAL_SYMBOL): Delete.
	(record_minimal_symbol): New function.
	(scan_xcoff_symtab): Replace uses of RECORD_MINIMAL_SYMBOL
	by call to record_minimal_symbol and set misc_func_recorded
	to 1.  Set last_csect_sec to the XCOFF section index instead
	of GDB's section_offset index.  Update calls to
	prim_record_minimal_symbol_and_info to pass the BFD section
	as well.
