[gdb][Arm]: gdb cannot step across CMSE secure entry function code.
GDB is not able to execute "step" command on function calls of Armv8-M cmse secure entry functions.
Everytime GNU linker come across definition of any cmse secure entry function in object file(s),
it creates two new instructions secure gateway (sg) and original branch destination (b.w),
place those two instructions in ".gnu.sgstubs" section of executable.
Any function calls to these cmse secure entry functions is re-directed through secure gateway (sg)
present in ".gnu.sgstubs" section.
Example:
Following is a function call to cmse secure entry function "foo":
...
bl xxxx <foo> --->(a)
...
<foo>
xxxx: push {r7, lr}
GNU linker on finding out "foo" is a cmse secure entry function, created sg and b.w instructions and
place them in ".gnu.sgstubs" section (marked by c).
The "bl" instruction (marked by a) which is a call to cmse secure entry function is modified by GNU linker
(as marked by b) and call flow is re-directly through secure gateway (sg) in ".gnu.sgstubs" section.
...
bl yyyy <foo> ---> (b)
...
section .gnu.sgstubs: ---> (c)
yyyy <foo>
yyyy: sg // secure gateway
b.w xxxx <__acle_se_foo> // original_branch_dest
...
0000xxxx <__acle_se_foo>
xxxx: push {r7, lr} ---> (d)
On invoking GDB, when the control is at "b" and we pass "step" command, the pc returns "yyyy"
(sg address) which is a trampoline and which does not exist in source code. So GDB jumps
to next line without jumping to "__acle_se_foo" (marked by d).
The above details are published on the Arm website [1], please refer to section 5.4 (Entry functions)
and section 3.4.4 (C level development flow of secure code).
[1] https://developer.arm.com/architectures/cpu-architecture/m-profile/docs/ecm0359818/latest/armv8-m-security-extensions-requirements-on-development-tools-engineering-specification

command at "b", so that the control jumps to "__acle_se_foo" (marked by d).

SHF_GNU_MBIND requires ELFOSABI_GNU
When SHF_GNU_MBIND was added in the SHF_LOOS to SHF_HIOS range, it
should have required ELFOSABI_GNU since these flags are already in use
by other OSes. HPUX SHF_HP_TLS in fact has the same value. That
means no place in binutils should test SHF_GNU_MBIND without first
checking OSABI, and SHF_GNU_MBIND should not be set without also
setting OSABI. At least, that's the ideal, but the patch accepts
SHF_GNU_MBIND on ELFOSABI_NONE object files since gas didn't always
set OSABI. However, to reinforce the fact that SHF_GNU_MBIND isn't
proper without a non-zero OSABI, readelf will display the flag as
LOOS+0 if OSABI isn't set.
The clash with SHF_HP_TLS means that hppa64-linux either has that flag
on .tbss sections or supports GNU_MBIND, not both. (hppa64-linux
users, if there are any, may have noticed that GNU ld since 2017
mysteriously aligned their .tbss sections to a 4k boundary. That was
one consequence of SHF_HP_TLS being blindly interpreted as
SHF_GNU_MBIND.) Since it seems that binutils, gdb, gcc, glibc, and
the linux kernel don't care about SHF_HP_TLS I took that flag out of
.tbss for hppa64-linux.

gdb: Show type summary for anonymous structures from c_print_typedef
Currently each language has a la_print_typedef method, this is only
used for the "info types" command.
The documentation for "info types" says:
Print a brief description of all types whose names match the regular
expression @var{regexp} (or all types in your program, if you supply
no argument).
However, if we consider this C code:
typedef struct {
int a;
} my_type;
Then currently with "info types" this will be printed like this:
3: typedef struct {
int a;
} my_type;
I see two problems with this, first the indentation is clearly broken,
second, if the struct contained more fields then it feels like the
actual type names could easily get lost in the noise.
Given that "info types" is about discovering type names, I think there
is an argument to be made that we should focus on giving _only_ the
briefest summary for "info types", and if the user wants to know more
they can take the type name and plug it into "ptype". As such, I
propose that a better output would be:
3: typedef struct {...} my_type;
The user understands that there is a type called `my_type`, and that
it's an alias for an anonymous structure type.
The change to achieve this turns out to be pretty simple, but only
effects languages that make use of c_print_typedef, which are C, C++,
asm, minimal, d, go, objc, and opencl. Other languages will for now
do whatever they used to do.
The patch to change how anonymous structs are displayed also changes
the display of anonymous enums, consider this code sample:
typedef enum {
AA, BB, CC
} anon_enum_t;
This used to be displayed like this:
3: typedef enum {AA, BB, CC} anon_enum_t;
Which will quickly become cluttered for enums with a large number of
values. The modified output looks like this:
3: typedef enum {...} anon_enum_t;
Again, the user can always make use of ptype if they want to see the
details of the anon_enum_t type.
It is worth pointing out that this change (to use {...}) only effects
anonymous structs and enums, named types don't change with this patch,
consider this code:
struct struct_t {
int i;
};
enum enum_t {
AA, BB, CC
};
The output from 'info types' remains unchanged, like this:
4: enum enum_t;
1: struct struct_t;
An additional area of interest is how C++ handles anonymous types used
within a typedef; enums are handled basically inline with how C
handles them, but structs (and classes) are slightly different. The
behaviour before the patch is different, and is unchanged by this
patch. Consider this code compiled for C++:
typedef struct {
int i;
} struct_t;
Both before and after this patch, this is show by 'info types' as:
3: typedef struct_t struct_t;
Unions are displayed similarly to structs in both C and C++, the
handling of anonymous unions changes for C in the same way that
it changes for anonymous structs.
I did look at ada, as this is the only language to actually have some
tests for "info types", however, as I understand it ada doesn't really
support typedefs, however, by forcing the language we can see what ada
would print. So, if we 'set language ada', then originally we printed
this:
3: record
a: int;
end record
Again the indentation is clearly broken, but we also have no mention
of the type name at all, which is odd, but understandable given the
lack of typedefs. If I make a similar change as I'm proposing for C,
then we now get this output:
3: record ... end record
Which is even less informative I think. However, the original output
_is_ tested for in gdb.ada/info_auto_lang.exp, and its not clear to me
if the change is a good one or not, so for now I have left this out.

gdb: Improve output from "info types" commad
This commit makes two changes to the "info types" command:
First, only use typedef_print for printing typedefs, and use
type_print for printing non-typedef scalar (non-struct) types. The
result of this is the output for builtin types goes from this:
typedef double;
typedef float;
typedef int;
to this:
double;
float;
int;
which seems to make more sense.
Next GDB no longer matches msymbols as possible type names. When
looking for function symbols it makes sense to report matching
msymbols from the text sections, and for variables msymbols from the
data/bss sections, but when reporting types GDB would match msymbols
of type absolute. But I don't see why these are likely to indicate
type names. As such I've updated the msymbol matching lists in
symtab.c:search_symbols so that when searching in the TYPES_DOMAIN, we
never match any msymbols.

Make documentation of "python" command match actual behavior
The example in the documentation for the "python" command shows GDB
outputting instructions for how to terminate a sequence of python
commands entered from the command line. The documentation shows that
the following two lines are being output, though this does not occur
when actually using the "python" command from GDB:
Type python script
End with a line saying just "end".
While display of this text might be helpful, GDB has several other
commands which also use the "end" terminator that offer no such text.
Examples include the "if" and "while" commands. For example,
(gdb) if 1==1
>print "a"
>end
$1 = "a"
This seems similar to doing:
(gdb) python
>print 23
>end
23
If we decide that we want the "python" command to print such a message,
we should also adjust the behavior for other GDB commands which also use
"end" to terminate a command list. I.e, if this decision is made, the
"if" and "while" commands ought to also print similar messages.
So, for the moment anyway, this commit adjusts the documentation of the
python command to match its implementation.
This patch was taken from a larger body of work originating from the
Archer project. I haven't been able to determine its original author,
though I did find a commit log from Jan Kratochvil (in the Archer
repository) which suggests that the change had originally been made to
gdb.texinfo, but got inadvertently dropped when the python related

gdb/riscv: Write 4-byte nop to dummy code region before inferior calls
When making inferior function calls GDB sets up a dummy code region on
the stack, and places a breakpoint within that region. If the random

place a compressed breakpoint, which can cause problems if the target
doesn't support compressed instructions.
This commit prevents this issue by writing a 4-byte nop instruction to

instruction in place, when we come to insert the breakpoint then an
uncompressed breakpoint will be used.

[PowerPC64] pc-relative TLS relocations
This patch supports using pcrel instructions in TLS code sequences. A
number of new relocations are needed, gas operand modifiers to
generate those relocations, and new TLS optimisation. For
optimisation it turns out that the new pcrel GD and LD sequences can
be distinguished from the non-pcrel GD and LD sequences by there being
different relocations on the new sequence. The final "add ra,rb,13"
on IE sequences similarly needs a new relocation, or as I chose, a
modification of R_PPC64_TLS. On pcrel IE code, the R_PPC64_TLS points
one byte into the "add" instruction rather than being on the
instruction boundary.

Rearrange TUI data window code
An earlier patch caused tui-windata.h to be essentially empty. And,
other earlier patches implemented TUI data window methods in any spot
that happened to be convenient at the time.
This patch rearranges all the data window code to be somewhat more
organized. It moves tui_data_window to tui-regs.h, and moves the
implementation of all methods to tui-regs.c. It then removes
tui-windata.h and tui-windata.c.
It also removes the "structuring" comments from tui-regs.c; these are
not the usual gdb style, and were out of date anyhow. Finally, it
moves _initialize_tui_regs to the end of the file, per the usual gdb
convention.

Fix flushing bug in tui_puts_internal
A while back I changed gdb not to flush in some places. It turned out
that this broke the TUI a little. An easy way to see it is to run
"gdb -tui -nx", then "file gdb" at the gdb prompt. gdb will print the
usual "Reading symbols..." message -- but it won't appear on-screen
until the reading is complete.
This patch changes the TUI to do the equivalent of line buffering in
tui_puts_internal.
