Improve bitop tree optimization
...
- Remove redundant casting
- Cheaper final XOR parity flip (~/^1 instead of != 0)
- Support XOR reduction of ~XOR nodes
- Don't add redundant masking of terms
- Support unmasked terms
- Add cheaper implementation for single bit only terms
- Ensure result is clean under all circumstances (this fixes current bugs)

Simplify redundant masking of AstShiftR/AstShiftL
...
AND(CONST,SHIFTR(_,C)) appears often after V3Expand, with C a large
enough dense mask (i.e.: of the form (1 << n) - 1) to make the masking
redundant. E.g.: 0xff & ((uint32_t)a >> 24). V3Const now replaces these
ANDs with the SHIFTR node.
Similarly, we also simplify the same with SHIFTL,
e.g.: 0xff000000 & ((uint32_t)a << 24)
2021-06-18 20:06:53 +01:00
0c93c3844f
Simplify AND(CONST,OR(_,_)) with redundant terms
...
V3Expand generates a lot of OR nodes that are under a clearing mask, and
have redundant terms, e.g.: 0xff & (a << 8 | b >> 24). The 'a << 8' term
in there is redundant as it's bottom bits are all zero where the mask is
non-zero. V3Const now removes these redundant terms.

Stop checking dtype for better optimization chance in BitOpTree ( #2909 )
...
* 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.
