| | * | | verilog_backend: dump attributes on CaseRule, as comments. | whitequark | 2019-07-08 | 1 | -6/+10 | |
| | | | | | | | | | | | | | Attributes are not permitted in that position by Verilog grammar. | |||||
| | * | | Allow attributes on individual switch cases in RTLIL. | whitequark | 2019-07-08 | 1 | -0/+5 | |
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The parser changes are slightly awkward. Consider the following IL: process $0 <point 1> switch \foo <point 2> case 1'1 assign \bar \baz <point 3> ... case end end Before this commit, attributes are valid in <point 1>, and <point 3> iff it is immediately followed by a `switch`. (They are essentially attached to the switch.) But, after this commit, and because switch cases do not have an ending delimiter, <point 3> becomes ambiguous: the attribute could attach to either the following `case`, or to the following `switch`. This isn't expressible in LALR(1) and results in a reduce/reduce conflict. To address this, attributes inside processes are now valid anywhere inside the process: in <point 1> and <point 3> a part of case body, and in <point 2> as a separate rule. As a consequence, attributes can now precede `assign`s, which is made illegal in the same way it is illegal to attach attributes to `connect`. Attributes are tracked separately from the parser state, so this does not affect collection of attributes at all, other than allowing them on `case`s. The grammar change serves purely to allow attributes in more syntactic places. | |||||
