	* minsyms.c (lookup_minimal_symbol_by_pc_name): New function.
	* symtab.h (lookup_minimal_symbol_by_pc_name): Add prototype.

	* symtab.c (fixup_section): Remove prototype.  Add ADDR parameter;
	use it instead of ginfo->value.address.  Look up minimal symbol by
	address and name.  Assume OBJFILE is non-NULL.
	(fixup_symbol_section): Ensure we always have an objfile to look
	into.  Extract and pass to fixup_section the symbol's address that
	will match the minimal symbol's address.
	(fixup_psymbol_section): Likewise.

	(find_pc_sect_psymtab): Fall back to non-addrmap case when debugging
	overlays and the addrmap returned the wrong section.

	* dwarf2read.c (var_decode_location): Set SYMBOL_CLASS before
	calling fixup_symbol_section.
