This should speed up the common case
as the compiler never operates on the
unescaped string.
The new escape function also fixes a bug
where ']' was not escaped even though it
is the delimiting character for FileInfo.
In order to maintain backwards
compatibility for the ProtoBuf format,
this patch adds escape/unescape calls
when going from/to protobuf format.
For better performance we should consider
changing the protobuf format.

For multi-line registers, the parsed source locator is located in a
different place in the concrete syntax tree than it is for other
Statements.

Test for #468
|
|
Workaround for #470. This allows parsing DoubleLits in subfield
expressions.
|
|
|
|
Also remove parsing support for ids with characters not supported in
Verilog nor in the Firrtl spec
|
|
Replace with more sensible comment to see LICENSE rather than including the
whole license in every file
|
|
Need many more, but this at least checks some DefMemory, DefRegister,
and keyword cases.
