Martin Povišer 26644ea779 equiv_simple: Drop hollow conditional 
All the listed flip-flop types would be known cells, so the extra part
of the conditional is without effect.

Rasmus Munk Larsen 4968229efc Speed up stringf / vstringf by 1.8x. 
The main speedup is accomplished by avoiding a heap allocation in the common case where the final string length is less than 128. Inlining stringf & vstringf adds an additional improvement.

Jannis Harder cc843d414f simplify: Avoid calling fixup_hierarchy_flags on nullptr 
Compiling on GCC hid this bug as it optimized the nullptr call away as
undefined behavior, but running the SBY tests with a clang build hits
this error.

Martin Povišer a511976b48 ast/simplify: Retire in_lvalue/in_param arguments to simplify 2023-09-26 13:32:15 +02:00
Martin Povišer 22b99413e8 ast/simplify: Make in_lvalue/in_param into props of AST nodes 
Instead of passing around in_lvalue/in_param flags to simplify, we make
the flags into properties of the AST nodes themselves. After the tree
is first parsed, we once do

  ast->fixup_hierarchy_flags(true)

to walk the full hierarchy and set the flags to their initial correct
values. Then as long as one is using ->clone(), ->cloneInto() and the
AstNode constructor (with children passed to it) to modify the tree, the
flags will be kept in sync automatically. On the other hand if we are
modifying the children list of an existing node, we may need to call

  node->fixup_hierarchy_flags()

to do a localized fixup. That fixup will update the flags on the node's
children, and will propagate the change down the tree if necessary.

clone() doesn't always retain the flags of the subtree being cloned. It
will produce a tree with a consistent setting of the flags, but the
root doesn't have in_param/in_lvalue set unless it's intrinsic to the
type of node being cloned (e.g. AST_PARAMETER). cloneInto() will make
sure the cloned subtree has the flags consistent with the new placement
in a hierarchy.

Add asserts to make sure the old and new way of determining the flags
agree.

Martin Povišer 10d0e69588 ast/simplify: Make tweaks in advance of big in_lvalue/in_param change 
The following commit will replace the way in_lvalue/in_param is being
tracked in the simplify code. Make tweaks in advance so that it will
be easier to make the old way and the new way agree.

These changes all should be innocuous.

Martin Povišer 986507f95f booth: Streamline the low-level circuit emission 
For the basic single-bit operations, opt for gate cells (`$_AND_` etc.)

move to the conventional module methods (`module->addAndGate`) away
from the local helpers. While at it, touch on the surrounding code.

Speed up the autoname pass by 3x. (#3945) 
* Speed up the autoname pass by 2x. This is accomplished by only constructing IdString objects for plain strings that have a higher score.

* Defer creating IdStrings even further. This increases the speedup to 3x.
