Marcelina Kościelnicka 119f79d8b9 Add support for new FF types in some opt passes. 2020-06-23 15:40:02 +02:00
Marcelina Kościelnicka b0bee396a8 Add new builtin FF types 
The new types include:

- FFs with async reset and enable (`$adffe`, `$_DFFE_[NP][NP][01][NP]_`)
- FFs with sync reset (`$sdff`, `$_SDFF_[NP][NP][01]_`)
- FFs with sync reset and enable, reset priority (`$sdffs`, `$_SDFFE_[NP][NP][01][NP]_`)
- FFs with sync reset and enable, enable priority (`$sdffce`, `$_SDFFCE_[NP][NP][01][NP]_`)
- FFs with async reset, set, and enable (`$dffsre`, `$_DFFSRE_[NP][NP][NP][NP]_`)
- latches with reset or set (`$adlatch`, `$_DLATCH_[NP][NP][01]_`)

The new FF types are not actually used anywhere yet (this is left
for future commits).

whitequark 21d44ebec7 minisat: add missing include guard for WASI. 
Including signal.h used to be allowed in WASI by mistake, but it's
an error since SDK 11.

pyosys: Use C++11 override keyword for bindings 
7191dd16 dropped the YS_OVERRIDE macro, but it was still being generated
by the python bindings generator, resulting in errors like these when
compiled with ENABLE_PYOSYS=1:

kernel/python_wrappers.cc:350:21: error: expected ‘;’ at end of member declaration
  350 |   virtual void help() YS_OVERRIDE;
      |                     ^

qbfsat: Fixes three bugs. 
1. Infinite loop in the optimization procedure when the first solution found while maximizing is at zero.
2. A signed-ness issue when maximizing.
3. Erroneously entering bisection mode with no wire to optimize.

whitequark c8c3c7af87 Use [[maybe_unused]] instead of YS_ATTRIBUTE(unused). 
[[maybe_unused]] is available since C++17, so this commit adds
a polyfill YS_MAYBE_UNUSED. Once we require C++17 we can drop it.

whitequark 2ffdb74fb1 Use (and ignore) the expression provided to log_assert in NDEBUG builds. 
This avoids warnings in NDEBUG builds emitted when a variable is only
used in log_assert, but is always defined.

Xiretza 817411044a
Add missing [[noreturn]] to log_file_error() 
Previously this was tagged only with YS_ATTRIBUTE(noreturn), but not
YS_NORETURN, so it got lost in #2173, resulting in warnings in
frontends/ast/simplify.cc:

frontends/ast/simplify.cc:267:1: warning: function declared 'noreturn' should not return [-Winvalid-noreturn]
}
^

Merge pull request #2171 from whitequark/cxxrtl-accessors 
cxxrtl: add .get() and .set() accessors on value<> and wire<>
 2020-06-19 03:52:29 +00:00
whitequark 962a2f3bff cxxrtl: add .get() and .set() accessors on value<> and wire<>. 
For several reasons:
  * They're more convenient than accessing .data.
  * They accommodate variably-sized types like size_t transparently.
  * They statically ensure that no out of range conversions happen.

For now these are only provided for unsigned integers, but eventually
they should be provided for signed integers too. (Annoyingly this
affects conversions to/from `char` at the moment.)

Fixes #2127.
