ec1b3fde8f Merge pull request #1711 from YosysHQ/cat/wasm-exception-cleanup 
Remove Wasm exception handling workarounds
 2026-05-01 13:34:28 +01:00

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.

33e1c9033b Improve file open error messages (#1700) 
Define open_(o|i)fstream_and_log_error in log.h to:
- quote 'filename'
- add error cause to easier troubleshoot
- use existing consistent string style
- easily allows OS specific message

Introduce it when file are opened and add it where error message
was missing.
