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.
