Updating todo text and assorted fixes 
Fix #3905 by removing emoji (and move the comment into the if block for less ambiguity).
Adds `latexmk` to README.

Note that latexpdf doesn't seem to like `cmd:ref` links, possibly because the
reference location is inside a latex comment block, but I was under the
impression that there was a reference location in there previously which was
working fine.  May be related to how the `cmd:def` block expands (or doesn't as
the case may be).

Makefile adjustments to match top make 
Hopefully matches enough that any `make docs` call will work from the yosys being built, while still being overridable locally.

Currently requires running twice from a clean build due to the way it finds `.dot` files to convert.

Martin Povišer f8325f66b7 opt_expr: Fix 'signed X>=0' replacement for wide output ports 
If the `$ge` cell we are replacing has wide output port, the upper bits
on the port should be driven to zero. That's not what a `$not` cell with
a single-bit input does. Instead opt for a `$logic_not` cell, which does
zero-pad its output.

Fixes #3867.

Martin Povišer 93988ef5df tests: Extend aigmap.ys with SAT comparison 
Extend the aigmap.ys test with SAT-based comparison of the original
cells and their AIG implementations.

This tests both the usual cells and the single-bit Yosys gates.

kernel/rtlil: Fixed the destruction guard for IdString 
The guard is optimised out on some compilers under certain conditions (eg: LTO on GCC) as constant under C++ lifetime rules.
This is because the guard type's member is invalid to access (UB) after the type has been destroyed, resulting in
`destruct_guard.ok` being unable to be `false` according to the optimiser, based on the lifetime rules.

This patch still invokes UB (all accesses to the destroyed IdString instance are), but at least the optimiser
can't reason that destruct_guard_ok cannot be false and therefore it's safe to optimise out from its guard role.

github-actions[bot] c7670b36d4 Bump version 2023-07-24 00:17:45 +00:00
Catherine 6965abeefa abc, abc9_exe: fix build on WASI (and others with `const* stdout`). 
C does not guarantee that stdout/stderr can be reassigned.
Most platforms do make them assignable, however musl and WASI that
is based on musl do not. WASI does not have `dup2()`; instead it has
its own non-portable version of it that can only assign to previously
allocated fds.

Update the stream redirection code so that it does the right thing
on WASI and other platforms.

Catherine 411b6e98cd abc, abc9_exe: respect `-q` when built with linked ABC. 
This is mostly important for YoWASP builds, since those do not have
a way to build with external ABC (I prototyped it but for some reason
ABC always segfaults when built as an independent Wasm binary...)

Martin Povišer 72a4022a10 ast/simplify: Retire 'at_zero' flag 
Now that all the callsites pass in 'false' for the flag (or propagate
the flag on recursion), we can retire it.

Martin Povišer 4fceeb3b32 ast/simplify: Use clone_at_zero() for "at_zero" evaluations 
The correct way of using the 'at_zero' regime of simplify is to perform
the simplification on a cloned AST subtree, otherwise the "at_zero"
evaluation seeps into the main tree.

Move the effect of the 'at_zero' flag to the cloning itself, so that
the simplify flag can be retired. We assume we can rely on id2ast in
the new clone method.

Martin Povišer 77d4b5230e ast: Move to a new helper method to print input errors 
It's a repeating pattern to print an error message tied to an AST
node. Start using an 'input_error' helper for that. Among other
things this is beneficial in shortening the print lines, which tend
to be long.
