Description

This line will cause an unterminated string error in VPreprocLex.l, although it is valid syntax:

$display("\nWarning!  This is a\
          string with a line\
          continuation\
          at time %0d PS", $time);

Here's a patch for VPreprocLex.l from Verilog-Perl-3.220:

113a114

<STRMODE>{backslash}{crnl} { linenoInc(); yymore(); }

VPreprocLex.l - This is a patched version that handles line continuations in strings (10.6 kB) Pete Nixon, 10/22/2009 05:33 pm

Indeed, thanks for the patch. A similar fix is needed for VParseLex.l

I committed the fix to git, it'll be in the next release.

Fixed in Verilog-Perl 3.221, and Verilator 3.720.
