The "tabset" command sets the tab width as used by the TUI for source
and disassembly display.
This command has long seemed to be misnamed to me. It is more in
keeping with gdb design to call it "set tui tab-width". Also, making
this change allows for the corresponding "show" command to work.

I've encountered a GDB crash when trying to read registers from a remote
stub that provided a target.xml with vector registers, but without the
'vec128' data type. The crash is caused by NULL register type entries for
the "concatenated" pseudo-registers v0-v15. These NULL entries are
introduced by the logic in s390_pseudo_register_type(), where the tdesc
type 'vec128' is returned unconditionally -- even if it doesn't exist (is
NULL).
The fixed logic for determining a "concatenated" vector register's type
now returns the type of the raw register v16 instead. This also makes
sure that all vector register have the same type.
gdb/ChangeLog:

The test loop in test_python_inline_or_multiline was not checking for the

Spotted this error because sometimes the gdb prompt does get processed
correctly and the final tests are run, causing it to show up in the

ERROR: can't read "ipalib": no such variable

This problem seems to come from commit
c708f4d256 ("gdb: Don't call gdb_load_shlib unless GDB is running")
which moved the gdb_load_shlib call in prepare_for_trace_test. In order

https://sourceware.org/ml/gdb-patches/2018-08/msg00347.html
Instead of going throttle and always enabling our selftests (even in
non-development builds), this patch is a bit more conservative and
introduces a configure option ("--enable-unit-tests") that allows the
user to choose whether she wants unit tests in the build or not. Note
that the current behaviour is retained: if no option is provided, GDB
will have selftests included in a development build, and will *not*
have selftests included in a non-development build.
The rationale for having this option is still the same: due to the
many racy testcases and random failures we see when running the GDB
testsuite, it is unfortunately not possible to perform a full test
when one is building a downstream package. As the Fedora GDB
maintainer and one of the Debian GDB uploaders, I feel like this
situation could be improved by, at least, executing our selftests
after the package has been built.
This patch introduces no regressions to our build.
OK?

Currently, signal frame handlers require explicitly coded calls to
trad_frame_set_reg_addr() to describe the location of saved registers
within a signal frame. This change permits the regcache_map_entry
arrays used with regcache::supply_regset and regcache::collect_regset
to be used to describe a block of saved registers given an initial
address for the register block.
Some systems use the same layout for registers in core dump notes,
native register sets with ptrace(), and the register contexts saved in
signal frames. On these systems, a single register map can now be
used to describe the layout of registers in all three places.
If a register map entry's size does not match the native size of a
register, try to match the semantics used by
regcache::transfer_regset. If a register slot is too large, assume
that the register's value is stored in the first N bytes and ignore
the remaning bytes. If the register slot is smaller than the
register, assume the slot holds the low N bytes of the register's
value. Read these low N bytes from the target and zero-extend them to
generate a register value.
While here, document the semantics for both regcache::transfer_regset
and trad_frame with respect to register slot's whose size does not
match the register's size.

This patch fixes the original problem - printing member in a virtual base,
using various expressions, do not yield the same value. Simple test case
below demonstrates the problem:
% cat t.cc
struct base { int i; };
typedef base tbase;
struct derived: virtual tbase { void func() { } };
int main() { derived().func(); }
% g++ -g t.cc
% gdb a.out
(gdb) break derived::func
(gdb) run
(gdb) p i
$1 = 0
(gdb) p base::i
$3 = 0
(gdb) p derived::i
$4 = 4196392
To fix the problem, add function get_baseclass_offset() which searches
recursively for the base class along the class hierarchy. If the base
is virtual, it uses "vptr" in virtual class object, which indexes to
its derived class's vtable, to get and returns the baseclass offset.
If the base is non-virtual, it returns the accumulated offset of its
parent classes. The offset is then added to the address of the class
object to access its member in value_struct_elt_for_reference().

PR tui/28819 points out that, in the TUI, the C-j and C-m keys cannot

The bug is that the TUI uses curses' "nl" mode, which causes wgetch to
return the same value for both keys. There is a "nonl" mode, but it
also affects output.

-Wshadow=local pointed out that the shadowing in gdbscm_frame_read_var
means that the ultimate call to read_var_value will always be passed
block==NULL. The fix is to remove the inner declaration.

* guile/scm-frame.c (gdbscm_frame_read_var): Remove inner
declaration of "block".
-Wshadow=local caught this buglet. fdwalk redeclares "result" in the
inner scope, meaning that this function will always return 0, even on
error.

* common/filestuff.c (fdwalk): Remove inner declaration of
"result".
-Wshadow=local found this latent bug. msp430-tdep.c does:
const gdb_byte *arg_bits;
{
/* Aggregates of any size are passed by reference. */
gdb_byte struct_addr[4];
[...
arg_bits = struct_addr;
}
... use arg_bits
Here, arg_bits can point to an object that's gone out of scope.
The fix is to hoist the inner "struct_addr" buffer to an outer scope,
and rename it to avoid shadowing.

* msp430-tdep.c (msp430_push_dummy_call): Rename inner
"structs_addr" and hoist declaration.
