src/gdb ChangeLog coffread.c testsuite/ChangeL ...


CVSROOT:	/cvs/src
Module name:	src
Changes by:	brobecke@sourceware.org	2013-03-29 02:04:15

Modified files:
	gdb            : ChangeLog coffread.c 
	gdb/testsuite  : ChangeLog 
Added files:

	gdb/testsuite/gdb.ada/win_fu_syms: foo.adb pck.adb pck.ads 

Log message:
	Ignore __fu<digits>__ symbols from COFF symbol tables
	
	The debugger sometimes prints strange function names for given
	addresses. For instance, with the following source code...
	
	4    procedure Foo is
	5       A : Integer;
	6    begin
	7       Do_Nothing (A'Address);
	8    end Foo;
	
	... we can see...
	
	(gdb) info line 5
	Line 5 of "foo.adb" starts at address 0x4017ca <_ada_foo+6>
	and ends at 0x4017d2 <_fu29__system__scalar_values__is_is4+7>.
	^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	
	_fu29__system__scalar_values__is_is4 is an artificial symbol
	generated by the linker, and interferes with the pc-to-symbol
	resolution.  There isn't much in the general minimal_symbol
	data that could help us identify them, so this patch changes
	the COFF reader to simply ignore them.
	
	gdb/ChangeLog:
	
	* coffread.c (is_import_fixup_symbol): New function.
	(record_minimal_symbol): Use is_import_fixup_symbol to
	detect import fixup symbols, and discard them.
	
	gdb/testsuite/ChangeLog:
	
	* gdb.ada/win_fu_syms: New testcase.
