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="${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,

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
Henner Zeller 68b5d0c3b1 Convert more log_error() to log_file_error() where possible. 
Mostly statements that span over multiple lines and haven't been

Wherever we can report a source-level location.
 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.
