Rupert Swarbrick 6aa0f72ae9 Silence spurious warning in Verilog lexer when compiling with GCC 
The chosen value shouldn't have any effect. I considered something
clearly wrong like -1, but there's no checking inside the generated
lexer, and I suspect this will cause even weirder bugs if triggered
than just setting it to INITIAL.

frontend: Include complete source location instead of just `location.first_line` in `frontends/ast/genrtlil.cc`. 2020-05-01 07:17:27 +00:00
whitequark b43c282e4e Add WASI platform support. 
This includes the following significant changes:
  * Patching ezsat and minisat to disable resource limiting code
    on WASM/WASI, since the POSIX functions they use are unavailable.
  * Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform
    does not support spawning subprocesses (i.e. Emscripten or WASI).
    This definition hides the definition of `run_command()`.
  * Adding a new Makefile flag, DISABLE_SPAWN, present in the same
    condition. This flag disables all passes that require spawning
    subprocesses for their function.

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.

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.

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.

Rupert Swarbrick 044ca9dde4 Add support for SystemVerilog-style `define to Verilog frontend 
This patch should support things like

  `define foo(a, b = 3, c)   a+b+c

  `foo(1, ,2)

which will evaluate to 1+3+2. It also spots mistakes like

  `foo(1)

(the 3rd argument doesn't have a default value, so a call site is
required to set it).

Most of the patch is a simple parser for the format in preproc.cc, but
I've also taken the opportunity to wrap up the "name -> definition"
map in a type, rather than use multiple std::map's.

Since this type needs to be visible to code that touches defines, I've
pulled it (and the frontend_verilog_preproc declaration) out into a
new file at frontends/verilog/preproc.h and included that where
necessary.

Finally, the patch adds a few tests in tests/various to check that we
are parsing everything correctly.

Marcus Comstedt 5e94bf0291 refixed parsing of constant with comment between size and value 
The three parts of a based constant (size, base, digits) are now three
separate tokens, allowing the linear whitespace (including comments)
between them to be treated as normal inter-token whitespace.
