symfpu_convert: Handle signed ints 
Use input wire `is_signed` to select between signed and unsigned handling.

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

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: Verifying rounding modes 
Works for everything but muladd.
Which I saw coming, but am still frustrated by.

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

Fixes #3515 2025-11-25 06:58:14 +13:00
Robert O'Callahan 9cb3a239cc Fix `subcircuit` building without `#define _YOSYS_` 
We can't use the new stringf functionality with `my_sprintf()` since in some builds
that falls back to C-style varargs.

libs/fst: Update upstream 
libfst is no longer included in gtkwave and instead has its own repo.  There has also been some refactoring, so the patches need to update to match, as does sim.cc.

Gabriel Somlo fe79a77e39 Fix undefined type error in libs/json11/json11.cpp 
Under certain conditions, compilation errors out with
the following message:

    "error: ‘uint8_t’ does not name a type"

Explicitly including <cstdint> prevents that situation.

libs/fst: Patch <io.h> 
I think what's happening here is that the _WIN64 fix is correct for 64bit windows, but (for whatever reason) the visual studio build is targeting 32bit windows, so the fix is unnecessary, but the upstream fix doesn't expect to be targeting 32bit windows and assumes all windows builds are 64bit... so fix that.
