gatemate: improve PLL->BUFG error message (#1739) 
When a PLL output is connected to a BUFG, it can only be connected to it.

The message is improved in mentioning it and listing all ports connected and the pll name.

This simplify debug.

YRabbit 175787b2f0
Gowin. BUGFIX. Alu optimization. (#1736) 
Adding freeing of the addition/subtraction mode switch PIP.

We're limiting optimization to just one constant input—cases with two
constant inputs are rare, and this raises questions about how such ALUs
are generated in synthesis.

LUT knowledge calculations have been replaced with table
constants—faster and easier to verify.

Merge pull request #1711 from YosysHQ/cat/wasm-exception-cleanup 
Remove Wasm exception handling workarounds
 2026-05-01 13:34:28 +01:00
Catherine 1407b33558 Ensure only non-truncating values are returned from `main()`. 
POSIX allows any `int` value to be returned but specifies that only
the low 8 bits are available in some contexts:
  https://pubs.opengroup.org/onlinepubs/9699919799/functions/_exit.html

For reasons that aren't entirely clear, WASI requires the value to be
in range [0;126), and this is enforced with an assertion at runtime
level in Wasmtime. This should probably be fixed in Wasmtime but until
it is done there doesn't seem to be any harm in returning `125` instead
of `-1`. This also removes any discrepancy due to truncation.
