Emil J 150c32b03e Merge pull request #6154 from YosysHQ/emil/liberty-filter 
liberty: add filtering for things we need
 2026-09-16 16:44:09 +00:00
nella 76213a5d4c Reject unknown internal cell types in check and hierarchy -check. 
A $-prefixed cell type must be a known cell type or a module in the
design. check reports it as a problem, hierarchy -check errors.

Miodrag Milanović e2c27aaafa Merge pull request #6042 from YosysHQ/krys/symfpu 
Add `symfpu` pass
 2026-07-20 10:20:23 +00:00
Miodrag Milanovic a7cfabd405 Fix gcc compile errors 2026-07-20 10:29:41 +02:00
Krystine Sherwin c2237447bf symfpu: Drop libs/ from symfpu includes 2026-07-20 09:58:04 +12:00

Krystine Sherwin d5b6a38f65 symfpu: Missed a space 2026-07-15 14:50:32 +12:00
Krystine Sherwin 7b5d334603 symfpu_convert: Handle signed ints 
Use input wire `is_signed` to select between signed and unsigned handling.
 2026-07-15 14:50:32 +12:00
Krystine Sherwin 50c4a057b2 symfpu: Use ubv for convert flags 2026-07-15 14:50:31 +12:00
Krystine Sherwin 675087937f symfpu: Convert with flags 2026-07-15 14:50:31 +12:00
Krystine Sherwin dfec87e6a3 symfpu: Add symfpu_convert 
Convert one input to three outputs (int -> float, float -> int, float -> float).
No rounding mode, no flags (yet).
 2026-07-15 14:50:31 +12:00
Krystine Sherwin 7a6b36b670 symfpu: Add -compare mode 
Also `min` and `max` ops.  RISC-V uses IEEE 754-2019 semantics where `min(+0,-0) == -0` and `max(+0,-0) == +0` so we do the same here.  We could make it optional, but as I understand it the newer behavior is still backwards compatible (since previously it was valid to have selected either).
 2026-07-15 14:50:30 +12:00
Krystine Sherwin 16f6e8dc6a Add symfpu -classify 
Add description text for standard `symfpu` signature.
 2026-07-15 14:50:30 +12:00
Krystine Sherwin 9943484dbc symfpu: Add altsqrt 
No denormalization here.  That can be a problem for later (or not at all).
 2026-07-15 14:50:29 +12:00
Krystine Sherwin 91928a7329 symfpu: Add alt2div 
`altdiv` but without denormalization, because as it turns out HardFloat unpacks subnorms in the same way, so lets just support both styles.
 2026-07-15 14:50:29 +12:00

Krystine Sherwin 2b39569477 symfpu: Configurable rounding modes 
Including tests, but currently only testing rounding modes on multiply.
Also missing the ...01 case.
 2026-07-15 14:50:25 +12:00
Krystine Sherwin 1347790f4d symfpu: Add flags 
Use symfpu fork.
Add tests for symfpu properties and extra edge case checking for flags.
