Zachary Snow 0f5b646ab8 sv: extended support for integer types 
- Standard data declarations can now use any integer type
- Parameters and localparams can now use any integer type
- Function returns types can now use any integer type
- Fix `parameter logic`, `localparam reg`, etc. to be 1 bit (previously 32 bits)
- Added longint type (64 bits)
- Unified parser source for integer type widths

Marcelina Kościelnicka 979347999f btor, smt2, smv: Add a hint on how to deal with funny FF types. 2021-02-25 22:04:04 +01:00
Marcelina Kościelnicka a651204efa Fix handling of unique/unique0/priority cases in the frontend. 
Basically:

- priority converts to (* full_case *)
- unique0 converts to (* parallel_case *)
- unique converts to (* parallel_case, full_case *)

Fixes #2596.

Merge pull request #2607 from zachjs/logger-error-atexit 
Fix double-free on unmatched logger error pattern
 2021-02-24 19:12:56 +00:00
Zachary Snow 5e439b6e3f Fix double-free on unmatched logger error pattern 
When an expected logger error pattern is unmatched, the logger raises
another (hidden) error. Because of the previous ordering of actions,
`logv_error_with_prefix()` would inadvertently invoke `yosys_atexit()`
twice, causing a double-free.
