symfpu: Use ubv for convert flags 2026-06-06 09:34:46 +12:00
Krystine Sherwin e9f77001df
symfpu: Convert with flags 2026-06-06 09:34:46 +12:00
Krystine Sherwin b0f9680fd9
symfpu: Add symfpu_convert 
Convert one input to three outputs (int -> float, float -> int, float -> float).
No rounding mode, no flags (yet).

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).

Add symfpu -classify 
Add description text for standard `symfpu` signature.

symfpu: Add altsqrt 
No denormalization here.  That can be a problem for later (or not at all).

Krystine Sherwin c6f6baf270
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.

symfpu: Configurable rounding modes 
Including tests, but currently only testing rounding modes on multiply.
Also missing the ...01 case.
 2026-06-06 09:34:41 +12:00

symfpu: Add flags 
Use symfpu fork.
Add tests for symfpu properties and extra edge case checking for flags.

Catherine afc0e78d11 Update top-level Python project for CMake compatibility. 
This commit reimplements the (no longer recommended) setuptools based
build system using a standards-based in-tree PEP517 build backend.
The implementation is partially based on
  https://codeberg.org/ziglang/zig-pypi/src/branch/main/make_wheels.py
which is licensed under BSD-0-clause.

It also adds a new option `YOSYS_BUILD_PYTHON_ONLY` that is available
only if the binary or the library aren't going to be installed, which
turns off these targets entirely, as well as some dependent ones
(e.g. tests).

Catherine a727e7f6e7 Migrate build system to CMake

Philippe Sauter c89cfe1e6e peepopt: add shiftpow2 pattern 
Rewrite power-of-two indexed word selects to $bmux when the shift
amount already carries the scale as low zero bits.

Keep the rule to non-overlapping selections and bound the generated
mux ways. Add regressions for aligned shifts, padding, signed
extension, and shiftmul handoff cases.

check_mem: Add -non-const option 
Can identify potentially dangerous addressing, but also prone to false-positives.
 2026-05-29 18:40:24 +12:00
Krystine Sherwin 07e3d648aa
Add check_mem command 
Comes with a set of tests which (currently) pass with `read_verilog` but fail with `verific` based on #5878.
Add `--check-sv`, an alternative to `--prove-sv` with generator defined yosys commands.  Helpful for when you want to run the same set of commands on a bunch of sv files.
