This would have made the issue in the pre-740543d4e code
much more obvious (the config option by itself does not
have any effect on the choice of active reference input).
Commit 740543d4e2 had unintentionally broken DRTIO
satellites, as si5324::setup is also used there. This
imports setup_si5324_as_synthesizer() from artiq-zynq,
where the input selection was already explicitly done.

This caused sporadic LoadFaults with LLD 14 and above, as they
happened to lay out the (not otherwise mentioned) GOT/PLT such
that they would overlap with the stack guard page.
LLD does support the --orphan-handling=error option, which
would be useful to avoid similar problems in the future, but
then we'd need to mention all the other misc sections
(symbol table, comments) in the linker script as well.
GitHub: Fixes#1975.
This should give even only mildly technical users a
chance to figure out what's going on, which empirically
is not the case for a plain Exception(LoadFault) without
further context.
Also factors out duplicate code for (de)serializing
elements of lists and ndarrays, and replaces the rounding
calculations by the well-known, much faster power-of-two-only
bit-twiddling version.
GitHub: Fixes#1934.
In particular, i64/double are actually supposed to be aligned
to their size on RISC-V (at least according to the ELF psABI),
though it is unclear to me whether this actually caused any
issues.
`llvm-addr2line` is not included as part of the llvm binary package for Windows. This causes ARTIQ python compilations issues when conda is not used (so the `llvm-tools` conda package is not installed, which provides `llvm-addr2line` currently).
Artiq assumes that all exceptions raised by the kernel can be constructed with
a single string argument. This isn't always the case. Especially for
exceptions that originated in python and were propagated to the kernel over
rpc.
With out this change a mosek solver failure looks like:
```

On the master/EnvExperiment side, the only addition is an optional

class Example(EnvExperiment):
argument_ui = "ndscan"
def build(self):
…
Clients – primarily artiq_dashboard, but in principle e.g. a
command-line UI could do the same – can then compare the value to a
list of well-known names and prefer any matching custom UI handlers.
On the dashboard side, this commit adds the mechanism to register
a custom argument editor for a given argument_ui string, i.e. the
widget that displays the parameter values within the wider
experiment UI shell with the submit button, pipeline parameters, and
so on. The registry remains empty by default and would be filled by
out-of-tree plugins such as ndscan.
The UI state readback is implemented somewhat defensively to avoid
needless disruptions to users when upgrading.
These are used by ndscan, as re-serialising the entire ndscan
parameter metadata tree, which can grow to be quite extensive,
on every single Qt change event is a bit excessive (and would
probably cause a bit of lag while typing for big experiments
on low-end machines).
This is analogous to the explist/schedule subscribers, and allows
custom argument editors (such as ndscan) to provide hints/defaults/…
from datasets once available.
This allows ndscan v0.3+ to use the IPC interface for efficiency;
previously, the non-upstreamed RID dataset namespace feature allowed
the applets to somewhat efficient subscribe directly to the master
process via the socket interface.
When serialising a list of objects `_send_rpc_value` makes a copy of the
upcoming tags to pass repeatedly to the recursive call. Then uses
`_skip_rpc_value` to skip over the tags that should have been processed.
This didn't handle numpy arrays so, after processing a list of arrays it
got out of sync and failed.

nac3ld will not generate PLT & its relocation section. There might not be a pltrel in that case.
On the other hand, rebinding will not be limited to the symbols in the PLT when linked with nac3ld.
Thus the renaming.
Instead of automatically closing and draining the TcpStream in the Drop
implementation instead expect the user to call TcpStream::close.
Add close called to all users of TcpStream.
Document the requirement to call close on TcpListener::accept, this seems
to be the only way to get a new TcpStream at the moment.

Main changes:
Deal with interfaces now being generic over mediums, update interface name
and initialisation.
Interfaces now own their sockets. So we store a reference to the Interface
instead of the SocketSet in Scheduler and IO.
Sockets are no longer reference counted. We never called the function to
increase the socket's reference count, so now we just remove it where it
was previously released. This will result in the socket being dropped at
a different time, but I think that should be fine.
Tested firmware upload to the bootloader and spamming artiq_coremgmt log
calls to download the log from the firmware.

The representation of TList(T) is changed from `{T*, u32}` to
`{T*, u32}*`. The old representation forbids changing the length of a
list when the list is passed as a parameter into functions, as the
length is passed by value. The representation now matches with nac3.

When we have a trys inside a loop then we want to make sure any
finallys are executed by break and continue inside this try. But
this shouldn't pull finallys defined outside the loop in to the
loop. This change resets the `outer_final` attribute when
visiting for and while loops so that this doesn't happen.

* init() now also clear and resets more state including the interpolators.
If not done, this PLL unlocks/locks may lead to random interpolator state

* Use and expose `t_frame`
* Clarify implementation state of `read()`
Otherwise, the exception message might be allocated on a stack, and will
become a dangling pointer when the exception is raised.
This will break some code that constructs exceptions with a function by
passing the message as a parameter because we cannot know if the parameter
is a constant. A way to mitigate this would be to defer this check to
LLVM IR codegen stage, and do inlining first for those exception
allocation functions, but I am not sure if we will guarantee inlining
for certain functions, and whether this is really needed.
Note that because we changed exception representation from using string
names as exception identifier into using integer IDs, we need to
initialize the embedding map in order to allocate the integer IDs. Also,
we can no longer print the exception names and messages from the kernel,
we will need the host to map exception IDs to names, and may need the
host to map string IDs to actual strings (messages can be static strings
in the firmware, or strings stored in the host only).
We now check for exception IDs for lit tests, which are fixed because we
preallocated all builtin exceptions.
Ported from:
M-Labs/artiq-zynq#162
This includes new API for exception handling, some refactoring to avoid
code duplication for exception structures, and modified protocols to
send nested exceptions and avoid string allocation.
Instead of removing basic blocks with no predecessor, we will now mark
and remove all blocks that are unreachable from the entry block. This
can handle loops that are dead code. This is needed as we will now
generate more complicated code for exception handling which the old dead
code eliminator failed to handle.
Exceptions are now allocated in the runtime when we raise the exception,
and destroyed when we exit the catch block. Nested exception and try
block is now supported, and should behave the same as in CPython.
Exceptions raised in except blocks will now unwind through finally
blocks, matching the behavior in CPython. Reraise will now preserve
backtrace.
Phi block LLVM IR generation is modified to handle landingpads, which
one ARTIQ IR will map to multiple LLVM IR.
Exception name is replaced by exception ID, which requires no
allocation. Other strings in the exception can now be 'host-only'
strings, which is represented by a CSlice with len = usize::MAX and
ptr = key, to avoid the need for allocation when raising exceptions
through RPC.

Removed test cases that do not respect lifetime/scope constraint.
See discussion in artiq-zynq repo: M-Labs/artiq-zynq#119
Referred to the patch from @dnadlinger. 5faa30a837
In the origin implementation, the `nowrite` flag literally means not writing memory at all.
Due to the usage of flags on certain functions, it results in the same issues found in artiq-zynq after optimization passes. (M-Labs/artiq-zynq#119)
A fix wrote by @dnadlinger can resolve this issue. (c1e46cc7c8)
The reason of the borrow stuff is explained in M-Labs/artiq-zynq#76 (artiq-zyna repo).
As for `cache_get()`, compiler will perform stack allocation to pre-allocate the returned structure, and pass to cache_get alongside the `key`.
However, ksupport fails to recognize the passed memory, so it will always assume the passed memory as the key.
