gdb: Support printf 'z' size modifier
The gdb format mechanism doesn't currently support the 'z' size
modifier, there are a few places in GDB where this is used. Instead
of removing these uses lets just add support to GDB for using 'z'.
I found this issue when trying to use some of the debug output.
Before this commit:
(gdb) set debug dwarf-line 9
(gdb) file test
Reading symbols from test...
Unrecognized format specifier 'z' in printf
(No debugging symbols found in test)
(gdb)
After this commit:
(gdb) set debug dwarf-line 9
(gdb) file test
Reading symbols from test...
Adding dir 1: /usr/include
Adding file 1: test.c
Adding file 2: stdc-predef.h
Processing actual line 3: file 1, address 0x4004a0, is_stmt 1, discrim 0
Processing actual line 4: file 1, address 0x4004a0, is_stmt 1, discrim 0
.... lots of debug output ...
Processing actual line 10: file 1, address 0x4003b7, is_stmt 0, discrim 0
(gdb)
I've added a self test to cover the integer format size modifiers,
including the 'z' modifier.
gdb/ChangeLog:
* gdbsupport/format.c (format_pieces::format_pieces): Support
printf 'z' size modifier.
* gdbsupport/format.h (enum argclass): Add size_t_arg.
* printcmd.c (ui_printf): Handle size_t_arg.
* ui-out.c (ui_out::vmessage): Likewise.
* unittests/format_pieces-selftests.c (test_format_int_sizes): New
function.
(run_tests): Call test_format_int_sizes.
gdb/gdbserver/ChangeLog:
* ax.c (ax_printf): Handle size_t_arg.
