Marcelina Kościelnicka bc717abad2 memory_dff: Remove code looking for $mux cells.
This job is now performed by `opt_dff`, which runs before this pass.

Marcelina Kościelnicka d555454969 tests/bram: Do not generate write address collisions.
These have no defined semantics, making the tests non-deterministic.

whitequark ab76d9cec5 cxxrtl: don't assert on edge sync rules tied to a constant.
These are commonly the result of tying an async reset to an inactive
level.

whitequark d1de08e38a cxxrtl: allow `always` sync rules in debug_eval.
These can be produced from `always @*` processes, if `-noproc`
is used.

Zachary Snow d738b2c127 sv: support for parameters without default values
- Modules with a parameter without a default value will be automatically
  deferred until the hierarchy pass
- Allows for parameters without defaults as module items, rather than
  just int the `parameter_port_list`, despite being forbidden in the LRM
- Check for parameters without defaults that haven't been overriden
- Add location info to parameter/localparam declarations

Zachary Snow 10a6bc9b81 verilog: fix sizing of ports with int types in module headers
Declaring the ports as standard module items already worked as expected.
This adds a missing usage of `checkRange()` so that headers such as
`module m(output integer x);` now work correctly.

Zachary Snow b6904a8e53 Set aside extraneous tests in simple_abc9 test suite
New test cases on one branch may be automatically copied from simple/ to
simple_abc9/, causing failures when switching to another branch. This
updates the simple_abc9 script to set aside extraneous tests in a
non-destructive way.

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 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.
