| | | | | | | | | | | | | | Calling back() on an empty string is not allowed and triggers an assert with recent gcc: $ cd manual/PRESENTATION_Intro $ ../../yosys counter.ys ... /usr/include/c++/8/bits/basic_string.h:1136: std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::back() [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>; std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference = char&]: Assertion '!empty()' failed. 802 if (label.back() == ':' && GetSize(label) > 1) (gdb) p label $1 = ""

* Documentation improvements etc.Ruben Undheim2018-10-131-3/+1
| | | | | | | | | - Mention new feature in the SystemVerilog section in the README file - Commented changes much better - Rename a few signals to make it clearer - Prevent warning for unused signals in an easier way - Add myself as copyright holder to 2 files - Fix one potential memory leak (delete 'wire' if not in modport)

|\ | | | | Consistent use of 'override' for virtual methods in derived classes.
| * Consistent use of 'override' for virtual methods in derived classes.Henner Zeller2018-07-208-32/+31
| | | | | | | | | | | | | | | | | | 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)

* Provide source-location logging.Henner Zeller2018-07-192-44/+45
| | | | | | | | 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.
