CFuncs only used to be split at procedure (always/initial/final block),
which on occasion can still yield huge output files if they have large
procedures. This patch make CFuncs split at statement boundaries within
procedures. This has the potential to help a lot, but still does not
help if there are huge statements within procedures.
V3Reloop now can roll up indexed assignments between arrays if there is a
constant offset between indices on the left and right hand sides, e.g.:
a[0] = b[2];
a[1] = b[3];
...
a[x] = b[x + 2];
* Tests: Add more case that does not match native C++ width (8, 16, 32 or 64).
* Use AstVarRef::same() instead of AstNode::sameGateTree() because the latter checks dtype in addition to scope.
AstVarRef may have different minWidth in some cases,
but the difference should be ignored in the context of bitOpTree optimization.
This support code merely adds the capability to skip over the encrypted
parts. Many models have unencrypted module interfaces with ports, and
only encrypt the critical parts.
* Tests: Add another testcase that triggers assertion failure in bitOpTree opt.
* Fix assertion failure in bitOpTree opt reported in #2891. Consider the follwoing case.
CCast -> WordSel -> VarRef(leaf)
* Make sure that m_bitPolarity is expanded enough.
The intention was to not merge impure assignments, but the actual
predicate failed if the assignment was indeed pure.
This fix gains 1.5% speed on SweRV EH1.
This will still warn if a case item is completely covered by previous
items, but will no longer complain about overlaps like this:
priority casez (foo_i)
2'b ?1: bar_o = 3'd0;
2'b 1?: bar_o = 3'd1;
Before, there was a warning for the second statement because the first
two patterns match 2'b11.
Add V3OptionsParser that can suggest correct option.
