| | | | | | | | | | | | | | | Some the of parser fixes may look strange but they were needed to avoid shift/reduce conflicts, due to the explicit parentheses in path_delay_value, and the mintypmax values without parentheses

| | | | | | | | | | | | | | | | | | | | | https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/master/vtr_flow/primitives.v , (specify block ignored). Must use 'read_verilog -defer' due to a parameter not assigned a default value.
| * | A few minor enhancements to specify block parsing.Udi Finkelstein2018-08-151-2/+13
| | | | | | | | | | | | Just remember specify blocks are parsed but ignored.
* | | Added -no_dump_ptr flag for AST dump options in 'read_verilog'Udi Finkelstein2018-08-233-9/+20
| | | | | | | | | | | | | | | | | | 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.
