Wilson Snyder ed25aaaad9 Internals: Fix g++ std11 warning. No functional change. 2023-09-01 17:59:30 -04:00
Yinan Xu b4b74d72f0
Add prepareClone and atClone APIs for Verilated models (#3503) (#4444) 
This API is used if the user copies the process using `fork`
and similar OS-level mechanisms. The `at_clone` member function
ensures that all model-allocated resources are re-allocated, such
that the copied child process/model can simulate correctly.

A typical allocated resource is the thread pool, which every model
has its own pool.

Remove --no-threads; require --threads 1 for single threaded (#3703). 2022-11-05 08:47:34 -04:00
Geza Lore 65e08f4dbf Make all expressions derive from AstNodeExpr (#3721). 
Apart from the representational changes below, this patch renames
AstNodeMath to AstNodeExpr, and AstCMath to AstCExpr.

Now every expression (i.e.: those AstNodes that represent a [possibly
void] value, with value being interpreted in a very general sense) has
AstNodeExpr as a super class. This necessitates the introduction of an
AstStmtExpr, which represents an expression in statement position, e.g :
'foo();' would be represented as AstStmtExpr(AstCCall(foo)). In exchange
we can get rid of isStatement() in AstNodeStmt, which now really always
represent a statement

Peak memory consumption and verilation speed are not measurably changed.

Partial step towards #3420

Add custom memory management for verilated classes (#3595) 
This change introduces a custom reference-counting pointer class that
allows creating such pointers from 'this'. This lets us keep the
receiver object around even if all references to it outside of a class
method no longer exist. Useful for coroutine methods, which may outlive
all external references to the object.

The deletion of objects is deferred until the next time slot. This is to
make clearing the triggered flag on named events in classes safe
(otherwise freed memory could be accessed).

Geza Lore 38e5b6c1ad Replace __gcov_flush with __gcov_dump 
__gcov_flush was a private function and was removed from later GCC
versions (at least from 11.2.0, possibly earlier). Replace with the
documented public __gcov_dump.
