Xiretza 695150b037
Add YS_FALLTHROUGH macro to mark case fall-through
C++17 introduced [[fallthrough]], GCC and clang had their own vendored
attributes before that. MSVC doesn't seem to have such a warning at all.

whitequark 41421f5dca ast, rpc: record original name of $paramod\* as \hdlname attribute.
The $paramod name mangling is not invertible (the \ character, which
separates the module name from the parameters, is valid in the module
name itself), which does not stop people from trying to invert it.

This commit makes it easy to invert the name mangling by storing
the original name explicitly, and fixes the firrtl backend to use
the newly introduced attribute.

Claire Wolf 4711fea6c0 Improved rewrite code for writing to bit slice (disabled for now)
This adds the new rewrite rule. But it's still missing a check that makes
sure the new rewrite rule is actually a valid substitute in the always
block being processed. Therefore the new rewrite rule is just disabled
for now.

Merge pull request #1918 from whitequark/simplify-improve_enum
ast/simplify: improve enum handling
2020-04-15 14:16:50 +00:00
whitequark 2106f78bb1 ast/simplify: improve enum handling.
Before this commit, enum values were serialized as attributes of form
  \enum_<width>_<value>
where <value> was a decimal signed integer.

This has multiple drawbacks:
  * Enums with large values would be hard to process for downstream
    tooling that cannot parse arbitrary precision decimals. (In fact
    Yosys also did not correctly process enums with large values,
    and would overflow `int`.)
  * Enum value attributes were not confined to their own namespace,
    making it harder for downstream tooling to enumerate all such
    attributes, as opposed to looking up any specific value.
  * Enum values could not include x or z, which are explicitly
    permitted in the SystemVerilog standard.

After this commit, enum values are serialized as attributes of form
  \enum_value_<value>
where <value> is a bit sequence of the appropriate width.

Jeff Wang 249876b614 support using previously declared types/localparams/params in package
(parameters in systemverilog packages can't actually be overridden, so
allowing parameters in addition to localparams doesn't actually add any
new functionality, but it's useful to be able to use the parameter
keyword also)
