Hi,
I see the following fails on arm-none-eabi target,
-var-list-children --simple-values struct_declarations ^M
^done,numchild="11",children=[...,child={name="struct_declarations.func_ptr_struct",exp="func_ptr_struct",numchild="0",value="0x0 <_ftext>",type="struct _struct_decl (*)(int, char *, long)",thread-id="1"},child={name="struct_declarations.func_ptr_ptr",exp="func_ptr_ptr",numchild="0",value="0x0 <_ftext>",type="struct _struct_decl *(*)(int, char *, long)",thread-id="1"},...
(gdb) ^M
FAIL: gdb.mi/mi-var-child.exp: listing of children, simple types: names, type and values, complex types: names and types
-var-set-format weird.func_ptr_ptr natural^M
^done,format="natural",value="0x0 <_ftext>"^M
(gdb) ^M
FAIL: gdb.mi/mi-var-display.exp: set format variable weird.func_ptr_ptr in natural
In the test, "0x0" is expected, but "0x0 <_ftext>" is in the output.
Function pointers point to address zero, and tests assume there is no
symbol on address zero. However, on my arm-none-eabi target, there is
a code symbol _ftext on address zero, and test fails. Note that "set
print symbol off" doesn't take effect for function pointer.
int (*f) (void);
f = main;
(gdb) p f
$1 = (int (*)(void)) 0x8048400 <main>
(gdb) set print symbol off
(gdb) p f
$2 = (int (*)(void)) 0x8048400 <main>
In order to erase the difference, we can assign some function address
explicitly to function pointer, so the test behaves in a unique way.
In this patch, we assign nothing1 and nothing2 to function pointers
func_ptr_struct and func_ptr_ptr respectively, and update test as the
source file is changed.
gdb/testsuite:
2014-10-14 Yao Qi <yao@codesourcery.com>
* gdb.mi/mi-var-child.c (nothing1): New function.
(nothing2): New function.
(do_children_tests): Set function pointers by nothing1 and
nothing2.
* gdb.mi/mi-var-child.exp: Step over new added statements.
Update test to match the new output.
* gdb.mi/var-cmd.c (nothing1): New function.
(nothing2): New function.
(do_children_tests): Set function pointers by nothing1 and
nothing2.
* gdb.mi/mi-var-display.exp: Update test to match output.
Step to the line specified by $line_dct_nothing.
Increase the number of lines to step.
