Martin Whitaker 542fe2cf77 Enable checks for VPI const-correctness. 
Note we only want these enabled when building the compiler and runtime
binaries. If we included the ICARUS_VPI_CONST definition in the global
CPP_FLAGS, that would propagate to the flags used by iverilog-vpi, so
would affect compilation of user VPI code.

Martin Whitaker 603ff303f5 Cleanly terminate vvp on SIGHUP or SIGTERM (GitHub issue #203). 2018-09-29 23:25:04 +01:00
Martin Whitaker b066a5815e Allow %c format to output null characters (GitHub issue #209) 
Currently $display et al. output nothing when the expression
corresponding to a %c format specification has the value 0. As
Verilog provides no other way to write raw bytes to a file, we
should allow 0 values to be written. Other simulators allow this.
 2018-09-29 21:22:17 +01:00
Martin Whitaker 0d494da702 Further fixes for const-correctness. 
- allow ICARUS_VPI_CONST to be pre-defined by the user
- use it for sizetf as well as for compiletf and calltf
- fix remaining warnings when it is defined as 'const'
 2018-09-29 12:04:16 +01:00
Martin Whitaker 8df2f0cadf Fix broken links to SourceForge bug/patch trackers (GitHub issue #207).

Martin Whitaker 11c826216a Fix for GitHub issue #198 - support octal display for thread variables. 2018-06-12 22:58:07 +01:00
Martin Whitaker 7ad5b59a6f Fix for GitHub issue #199: handle signed division overflow. 
When performing a signed division or modulus operation using native
arithmetic, trap the special case that the numerator is the minimum
integer value and the denominator is -1, as this gives an undefined
result in C++.
 2018-06-12 21:59:58 +01:00
Martin Whitaker 6e49ab10ec Further fix for br1029. 
The code in vpi_callback.cc is replicated in vpi_vthr_vector.cc,
so we have to replicate the fix. This should really be factored
out.
 2018-05-14 22:14:51 +01:00
Martin Whitaker 87c01c55c0 Don't allow non-vectorable arguments to $signed/$unsigned. 
This led to an assertion failure in many cases (see br1029).
1364-2012 indicates it is illegal.

Martin Whitaker 69d80839a5 Improved check for missing task/function port direction. 2018-02-21 20:07:13 +00:00
Martin Whitaker 6b1b402a79 Fix for br1027: incorrect inference of task/function port direction. 
In traditional Verilog, each task_port_item must have an explicit port
direction.

In SystemVerilog, if the port direction is not specified, it should be
inherited from the preceding task_port_item for that task/function, and
only the first task_port_item should infer the direction to be 'input'.

Merge pull request #181 from phire/portinfo_grammar 
vvp grammar: .port_info statements should require/generate semicolons.

Scott Mansell d01e5accc0 vpp: Require semicolon after .port_info statements

Scott Mansell 7b84b29bbc tgt-vvp: Output semicolon after .port_info statements 
Backwards compatablity is perserved due to the parser interperting the
unexpected semicolon as an empty statement.
