whitequark efa278e232 Fix typographical and grammatical errors and inconsistencies. 
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.

Udi Finkelstein 042b3074f8 Added -no_dump_ptr flag for AST dump options in 'read_verilog' 
This option disables the memory pointer display.
This is useful when diff'ing different dumps because otherwise the node pointers
makes every diff line different when the AST content is the same.

Some the of parser fixes may look strange but they were needed to avoid shift/reduce conflicts,

Clifford Wolf e275692e84 Verific: Produce errors for instantiating unknown module

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
 2018-07-20 23:51:06 -07:00
Henner Zeller 3101b9b8c9 Fix remaining log_file_error(); emit dependent file references in new line. 
There are some places that reference dependent file locations ("this function was
called from ..."). These are now in a separate line for ease of jumping to
it with the editor (behaves similarly to compilers that emit dependent
messages).
 2018-07-20 18:52:52 -07:00

 2018-07-20 08:19:06 -07:00
Henner Zeller 1a60126a34 Provide source-location logging. 
o Provide log_file_warning() and log_file_error() that prefix the log
  message with <filename>:<lineno>: to be easily picked up by IDEs that
  need to step through errors.
o Simplify some duplicate logging code in kernel/log.cc
o Use the new log functions in genrtlil.

Udi Finkelstein 6378e2cd46 First draft of Verilog parser support for specify blocks and parameters. 
The only functionality of this code at the moment is to accept correct specify syntax and ignore it.
No part of the specify block is added to the AST

Udi Finkelstein 2b9c75f8e3 This PR should be the base for discussion, do not merge it yet! 
It correctly detects reg/wire mix and incorrect use on blocking,nonblocking assignments within blocks and assign statements.

What it DOES'T do:
Detect registers connected to output ports of instances.

Where it FAILS:
memorty nonblocking assignments causes spurious (I assume??) errors on yosys-generated "_ADDR", "_DATA", "EN" signals.

You can test it with tests/simple/reg_wire_error.v (look inside for the comments to enable/disable specific lines)

Udi Finkelstein e951ac0dfb $size() now works correctly for all cases! 
It seems the issues was that AST_MULTIRANGE is converted into a multirange_dimensions[] array on the AST_MEMORY node directly.

Udi Finkelstein 6ddc6a7af4 $size() seems to work now with or without the optional parameter. 
Multidimensional arrays still don't work. I suspect the problem is that the array is flattened into a 1D array before $size() is evaluated.
