Subject: [PATCH] sim: filter out SIGSTKSZ [PR sim/28302]
We map target signals to host signals so we can propagate signals
between the host & simulated worlds. That means we need to know
the symbolic names & values of all signals that might be sent.
The tools that generate that list use signal.h and include all
symbols that start with "SIG" so as to automatically include any
new symbols that the C library might add. Unfortunately, this
also picks up "SIGSTKSZ" which is not actually a signal itself,
but a signal related setting -- it's the size of the stack when
a signal is handled.
By itself this doesn't super matter as we will never see a signal
with that same value (since the range of valid signals tend to be
way less than 1024, and the size of the default signal stack will
never be that small). But with recent glibc changes that make this
into a dynamic value instead of a compile-time constant, some users
see build failures when building the sim.
As suggested by Adam Sampson, update our scripts to ignore this
symbol to simplify everything and avoid the build failure.

Subject: [PATCH] Fix build on rhES5
The rhES5 build failed due to an upstream import a while back. The
bug here is that, while the 'personality' function exists,
ADDR_NO_RANDOMIZE is only defined in <linux/personality.h>, not
<sys/personality.h>.
However, <linux/personality.h> does not declare the 'personality'
function, and <sys/personality.h> and <linux/personality.h> cannot
both be included.
This patch restores one of the removed configure checks and updates
the code to check it.
We had this as a local patch at AdaCore, because it seemed like there
was no interest upstream. However, now it turns out that this fixes
PR build/28555, so I'm sending it now.

Subject: [PATCH] [AArch64] Make gdbserver register set selection dynamic
The current register set selection mechanism for AArch64 is static, based
on a pre-populated array of register sets.
This means that we might potentially probe register sets that are not
available. This is OK if the kernel errors out during ptrace, but probing the
tag_ctl register, for example, does not result in a ptrace error if the kernel
supports the tagged address ABI but not MTE (PR 28355).
Making the register set selection dynamic, based on feature checks, solves
this and simplifies the code a bit. It allows us to list all of the register
sets only once, and pick and choose based on HWCAP/HWCAP2 or other properties.
