gdb/python: introduce gdb.TargetConnection object type
This commit adds a new object type gdb.TargetConnection. This new
type represents a connection within GDB (a connection as displayed by
'info connections').
There's three ways to find a gdb.TargetConnection, there's a new
'gdb.connections()' function, which returns a list of all currently
active connections.
Or you can read the new 'connection' property on the gdb.Inferior
object type, this contains the connection for that inferior (or None
if the inferior has no connection, for example, it is exited).
Finally, there's a new gdb.events.connection_removed event registry,
this emits a new gdb.ConnectionEvent whenever a connection is removed
from GDB (this can happen when all inferiors using a connection exit,
though this is not always the case, depending on the connection type).
The gdb.ConnectionEvent has a 'connection' property, which is the
gdb.TargetConnection being removed from GDB.
The gdb.TargetConnection has an 'is_valid()' method. A connection
object becomes invalid when the underlying connection is removed from
GDB (as discussed above, this might be when all inferiors using a
connection exit, or it might be when the user explicitly replaces a
connection in GDB by issuing another 'target' command).
The gdb.TargetConnection has the following read-only properties:
'num': The number for this connection,
'type': e.g. 'native', 'remote', 'sim', etc
'description': The longer description as seen in the 'info
connections' command output.
'details': A string or None. Extra details for the connection, for
example, a remote connection's details might be
'hostname:port'.

RISC-V: The vtype immediate with more than the defined 8 bits are preserved.
According the rvv spec,
https://github.com/riscv/riscv-v-spec/blob/master/vtype-format.adoc
The bits of vtype immediate from 8 to (xlen - 1) should be reserved.
Therefore, we should also dump the vtype immediate as numbers, when
they are set over 8-bits. I think this is a bug that we used to support
vediv extension and use the bit 8 and 9 of vtype, but forgot to update
the behavior when removing the vediv.
Consider the testcases,
vsetvli a0, a1, 0x700 # the reserved bit 10, 9 and 8 are used.
vsetvli a0, a1, 0x400 # the reserved bit 10 is used.
vsetvli a0, a1, 0x300 # the reserved bit 9 and 8 are used.
vsetvli a0, a1, 0x100 # the reserved bit 8 is used.
vsetivli a0, 0xb, 0x300 # the reserved bit 9 and 8 are used.
vsetivli a0, 0xb, 0x100 # the reserved bit 8 is used.
The original objdump shows the following result,

Allow DW_ATE_UTF for Rust characters
The Rust compiler plans to change the encoding of a Rust 'char' type
to use DW_ATE_UTF. You can see the discussion here:
https://github.com/rust-lang/rust/pull/89887
However, this fails in gdb. I looked into this, and it turns out that
the handling of DW_ATE_UTF is currently fairly specific to C++. In
particular, the code here assumes the C++ type names, and it creates
an integer type.
This comes from commit
53e710acd ("GDB thinks char16_t and char32_t
are signed in C++"). The message says:
Both places need fixing. But since I couldn't tell why dwarf2read.c
needs to create a new type, I've made it use the per-arch built-in
types instead, so that the types are only created once per arch
instead of once per objfile. That seems to work fine.
... which is fine, but it seems to me that it's also correct to make a
new character type; and this approach is better because it preserves
the type name as well. This does use more memory, but first we
shouldn't be too concerned about the memory use of types coming from
debuginfo; and second, if we are, we should implement type interning
anyway.
Changing this code to use a character type revealed a couple of
oddities in the C/C++ handling of TYPE_CODE_CHAR. This patch fixes
these as well.
I filed PR rust/28637 for this issue, so that this patch can be
backported to the gdb 11 branch.

sim: testsuite: initial support for OS-specific tests
We usually test against the newlib/libgloss environment, but for a
few ports that also support Linux apps, we want to test that logic
too. A lot of the C code is written such that it works with either
newlib/libgloss or glibc/linux toolchains, but we have some tests
that end up being Linux-specific. Cris has been using the target
tuple as a rough proxy for this (where cris*-*-elf is assumed to be
newlib/libgloss, and everything else is glibc/linux), but that is a
bit too rough, and it doesn't work in a multitarget build.
So lets create a few stub files that we can do compile tests with
to detect the different setups, and then let tests declare which
one they require (if they require any at all).

PR gdb/28480: Improve ambiguous member detection
Basic ambiguity detection assumes that when 2 fields with the same name
have the same byte offset, it must be an unambiguous request. This is not
always correct. Consider the following code:
class empty { };
class A {
public:
[[no_unique_address]] empty e;
};
class B {
public:
int e;
};
class C: public A, public B { };
if we tried to use c.e in code, the compiler would warn of an ambiguity,
however, since A::e does not demand an unique address, it gets the same
address (and thus byte offset) of the members, making A::e and B::e have the
same address. however, "print c.e" would fail to report the ambiguity,
and would instead print it as an empty class (first path found).
The new code solves this by checking for other found_fields that have
different m_struct_path.back() (final class that the member was found
in), despite having the same byte offset.
The testcase gdb.cp/ambiguous.exp was also changed to test for this
behavior.

gdb: fix crash when reading ECOFF debug information
In commit:
commit

Remove cleanups from mdebugread.c
the following change was made in the function parse_partial_symbols in
mdebugread.c:
- fdr_to_pst = XCNEWVEC (struct pst_map, hdr->ifdMax + 1);
- old_chain = make_cleanup (xfree, fdr_to_pst);
+ gdb::def_vector<struct pst_map> fdr_to_pst_holder (hdr->ifdMax + 1);
+ fdr_to_pst = fdr_to_pst_holder.data ();
The problem with this change is that XCNEWVEC calls xcalloc, which in
turn calls calloc, and calloc zero initializes the allocated memory.
In contrast, the new line gdb::def_vector<struct pst_map> specifically
does not initialize the underlying memory.
This is a problem because, later on in this same function, we
increment the n_globals field within 'struct pst_map' objects stored
in the vector. The incrementing is now being done from an
uninitialized starting point.
In this commit we switch from using gdb::def_vector to using
std::vector, this alone should be enough to ensure that the fields are
initialized to zero.
However, for extra clarity, I have also added initial values in the
'struct pst_map' to make it crystal clear how the struct will start
up.

configure.ac: Check for the readline.h explicitly
When readline development package is missing make fails with
"configure: error: system readline is not new enough" which
might be confusing. This patch checks for the readline.h explicitly
and makes make to warn about the missing package.

AArch64: Add support for AArch64 EFI (efi-*-aarch64).
This adds support for efi-*-aarch64 by virtue of adding a new PEI target
pei-aarch64-little. This is not a full target and only exists to support EFI
at this time.
This means that this target does not support relocation processing and is mostly
a container format. This format has been added to elf based aarch64 targets
such that efi images can be made natively on Linux.
However this target is not valid for use with gas but only with objcopy.
With these changes the resulting file is recognized as an efi image by
third party tools:
